Since Mercedes-Benz launched EQS, which is known as the high-end luxury flagship, it recently launched its first joint-venture domestic pure electric vehicle based on EVA platform, EQE, with a price range of 528-585,000 yuan. The price range of 500,000 is the mainstream market of pure electric luxury cars in China, so what is the driving impression of this medium and large luxury pure electric car produced according to the standard of "Made in China, Global Quality"? A few days ago, we experienced a real car in a 4S shop. Let’s find out!

The new EQE is the first pure electric vehicle of Mercedes -EQ brand developed in China based on EVA platform, and it is a milestone on the road of "all-electric" transformation of Mercedes-Benz. The new EQE has been further upgraded on the basis of inheriting many EQS pioneer luxury designs and excellent configurations, and has perfectly integrated the practicality of cars with the elegance of four-door coupe, creating a brand-new luxury market segment.

The coupe is both practical and luxurious, both inside and outside.

Mercedes-Benz EQE follows EQS’s pioneering and luxurious design style in appearance design, creating a harmonious and smooth coupe posture with a length of 4,969 mm and a wheelbase of 3,120 mm. The bow design created by pure electric platform brings ultra-low drag coefficient as low as 0.22, revealing elegance and luxury from the bones.

Appearance: elegant pioneer exquisite texture

Mercedes-Benz EQE comes standard with adaptive far and near light, and the high-profile models are also equipped with 1.3 million pixel intelligent digital headlights, which can realize accurate beam distribution according to road conditions, which is also rare in this class of models. Mercedes-Benz EQE’s front face "Night Star Array" closed grille complements the intelligent digital headlights with a lighting effect of 2.6 million pixels. The 3D penetrating spiral taillights continue the amazing lighting effect, and the 20-inch AMG aerodynamic wheel not only helps the battery life, but also highlights the dynamic temperament. It is equipped with EQ-specific projection themes of "electro-optical Shi Huo" and "meteor shower", and "electricity" illuminates every trip of the owner. The first special edition of 350 is decorated with the "EDITION ONE" logo and comes standard with night components, which is even more extraordinary.

Interior: luxury quality and texture are very good.

Mercedes-Benz EQE highlights the sense of technology and luxury in the interior design layout, which echoes the exterior design. The luxury cockpit of the new EQE fully mobilizes the multi-dimensional sensory experience-the 12.3-inch instrument screen from the S-class car and the 12.8-inch central control screen with the highest resolution of 210ppi, combined with the use of large-area walnut decorative panels, are particularly exquisite in visual effect. In addition, Mercedes-Benz EQE is also equipped with 64-color active ambient light, and the color of the light strip can change with the vehicle speed, creating a dynamic flow effect. Mercedes-Benz EQE is equipped with a full LCD instrument with a size of 12.3 inches. In addition to displaying rich driving data, it is also equipped with a variety of mode switching to present better visual effects and create more digital atmosphere for the interior.

Details: at your fingertips, advanced texture

Panoramic skylight with electric sunshade protects the cool inside of the car for drivers and passengers; No.6 sweet and bitter fragrance (equipped in the future) further demonstrates the luxurious atmosphere created by EQ family models; Listen to the ear, and the Burmester? Sound Surround Stereo System with 15 speakers makes two kinds of personalized analog sounds "sound" enter people’s hearts; In terms of the comfort of drivers and passengers, the seat of Mercedes-Benz EQE continues the comfort and luxury of Mercedes-Benz. The seat is covered with Nappa leather and matched with Paris nail-patterned solid buttons, which shows advanced texture; The ride feels spacious and soft, and the double-sided sound insulation glass in the front row makes the ride atmosphere more quiet and comfortable. Mercedes-Benz EQE has a number of practical storage spaces in the front and rear rows of the car, so people in the car can put things neatly at will to ensure the cleanliness of the car space as new.

The new EQE not only has surging power, but also creates outstanding driving quality in all directions with steady braking, flexible control and intelligent travel, making every journey full of pleasure.

Power: abundant power and long battery life: For electric vehicles, braking performance is closely related to kinetic energy recovery. On the basis of excellent braking performance, the new EQE provides four-speed kinetic energy recovery systems of D+, D, D- and D Auto. Among them, in the D Auto mode, the new EQE can intelligently adjust the kinetic energy recovery according to the driving state and driving mode of the vehicle, and even decelerate to a stop without using the brake pedal to ensure excellent braking effect of the vehicle at all times. In addition, Mercedes-Benz’s self-developed battery management system can reach a maximum of 128 kilowatts of DC charging (which can replenish the power from 10% to 80% within 48 minutes), greatly alleviating the "mileage anxiety" of pure trams.

Travel: rear wheel steering quality chassis The new EQE is equipped with four-link front suspension and multi-link rear suspension, and four-wheel independent suspension is supplemented by outstanding adjustment, which creates the chassis texture of Mercedes-Benz quality. The 350 prototype special edition comes standard with a rear wheel active steering system up to 10 degrees, and the turning diameter is as low as 10.7 meters, which gives the new EQE the flexibility comparable to that of a compact car. When the speed is less than 60 km/h, the rear wheel and the front wheel rotate in the opposite direction, and they can freely shuttle through the narrow roadway; When the speed exceeds 60 km/h, the rear wheel and the front wheel rotate in the same direction, and high-speed cornering or emergency lane change can be handled with equanimity; When the automatic parking function is turned on to drive out of the parking space, the front and rear wheels can also rotate at the same angle, so that the vehicle can walk out of the street in a "dressage".

People-oriented exclusive configuration of digital technology has been fully upgraded.

The new EQE inherits many people-oriented technology configurations of EQS, and at the same time, it also upgrades many exclusive configurations for the China market, in order to better meet the digital technology and localization functions of China customers’ usage habits and empower them for a better trip.

Zero-level operation scene push: The new EQE is equipped with a "zero-level interface", which always puts the core functions at the top of the desktop. Car owners can also log in individual user settings with fingerprints, open an efficient digital experience at the touch of their fingertips, and enjoy the convenience brought by many localized applications. In addition, the upgraded "mind-reading assistant" can intelligently push according to customers’ usage habits, and at the same time, it can realize domestic leading full-scene function recommendation, such as accepting Tencent video push at any time while waiting for parking and charging. The new EQE also supports wireless CarPlay screen projection function, which seamlessly projects the mobile phone interface in full screen, making the interaction more diverse and convenient.

Deep integration of customized navigation: The new EQE is equipped with high-tech customized navigation, and the functions of EQ optimized navigation, AR real-life crossing navigation and other aircraft are deeply integrated with the navigation system. AR real-life navigation can accurately distinguish the correct navigation entrance, and the navigation system can also accurately distinguish the parking floor, showing the brand temperature on the basis of technology. After the upgrade of "Mind-reading Voice Assistant", not only the intonation is more lifelike, but also the vehicle can recognize the combined instructions and listen to them in 15 seconds, and provide encyclopedia material interaction, so that voice control can open the world at any time.

Quiet, fresh and exclusive upgrade: The new EQE provides rear seats optimized for China customers, as well as front-row bilateral sound insulation glass and vehicle acoustic package as standard in China. It is also equipped with HEPA high-efficiency filtration system with a filtration effect of 99.75% in the "Changxin Air Shield", providing a cabin space that is always quiet and fresh. According to the localization needs of customers in China, the new EQE provides up to 10 local exclusive upgrade configurations, including rear gentleman function, rear central armrest, rear sunroof sunshade button, comfortable rear headrest, etc., so that every driver and passenger can enjoy exclusive luxury travel experience.

The new EQE is an important milestone on the road of Mercedes-Benz’s "all-electric" transformation, announcing the acceleration of the electrification process. As the 4 millionth car rolled off the production line in Beijing Benz factory, the new EQE was made in Shunyi factory. Beijing Benz Shunyi Factory strictly implements "Made in China, Global Quality" and has four characteristics: digitalization, flexibility, high efficiency and sustainability, and implements the enterprise’s sustainable development commitment and carbon-neutral production target. Beijing Benz Shunyi Factory reduces energy consumption through advanced production technologies and measures such as dry painting and ground source heat pump. Vigorously develop photovoltaic power generation and increase the proportion of self-made green energy; Beijing Benz also bought green electricity last year, becoming one of the first enterprises in Beijing to buy green electricity. The whole vehicle adopts a steel-aluminum hybrid body, and some structural parts of the body are made of 100% recyclable steel, effectively reducing the energy consumption output by 60%. Using more than 20% aluminum material can reduce the weight by 51.29 kg on the basis of ensuring structural strength, and NVH components can reduce the weight by about 14 kg on the basis of ensuring outstanding effect, further improving energy efficiency.

Although the test drive experience lasted only one day, Mercedes-Benz EQE left a deep impression on us in the actual driving. First of all, in terms of power output, Mercedes-Benz EQE feels linear output in economy and comfort mode, relaxed but not impatient, and can experience the smoothness of driving while driving. When switching to sports mode, with the personalized sound system, you can’t feel that this is a pure tram, with abundant power and sensitive acceleration. As a medium and large car with a length of nearly 5 meters and a wheelbase of more than 3 meters, the power steering and shock absorption adjustment of Mercedes-Benz EQE are very delicate, and the sense of stable control during steering is particularly practical, which can be seen as the heritage of an old luxury brand. After finely bumpy road sections, the chassis adjustment of Mercedes-Benz EQE makes us basically feel no vibration, but when passing through a large pothole road surface, the road feel will be clearer, but the front seats can absorb most of the vibration.

In addition, Mercedes-Benz EQE has added many practical functions in science and technology. For example, by integrating the real road with navigation tips through AR technology, we can clearly see the turn signs and street signs on the real road through the central control screen. This feeling is quite novel and interesting, and the guiding effect is very intuitive.

Mercedes-Benz EQE, which follows most designs and configurations of EQS, has done a remarkable job in appearance design, atmosphere creation, spatial layout, intelligent assistance and power adjustment. From this model, we can see the intention and determination of Mercedes-Benz, a luxury brand, in electric transformation.

The transformation of old urban residential areas is an important measure to enhance the sense of acquisition of ordinary people, and it is also an important content of implementing urban renewal actions. In the first half of this year, the renovation of old urban communities progressed smoothly. Recently, seven departments, including the Ministry of Housing and Urban-Rural Development, jointly issued the Notice on Solidly Promoting the Renovation of Old Urban Residential Areas in 2023 (hereinafter referred to as the Notice), demanding that the renovation plan of old urban residential areas in 2024 be reasonably arranged, indicating that China will continue to promote the renovation of old urban residential areas, which will benefit more urban residents.

Positive progress has been made in the transformation.

Ni Hong, Minister of Housing and Urban-Rural Development, said in an interview at the "Ministerial Channel" of the National People’s Congress this year that in the past five years, 167,000 old residential areas have been renovated nationwide, benefiting more than 29 million households and more than 80 million residents. In 2023, it is hoped that more than 50,000 old communities will be rebuilt, so as to benefit 20 million residents.

The data shows that from 2019 to 2022, in the process of renovation of old residential areas, all localities have renovated over 200,000 kilometers of aging pipelines such as water, electricity and heat letters, installed 70,000 elevators, added and upgraded 2.4 million parking spaces, added 63,000 charging piles for electric vehicles, and added 45,000 community service facilities such as old-age care.

Since the beginning of this year, the renovation of old residential areas has progressed smoothly. According to statistics from the Ministry of Housing and Urban-Rural Development, in 2023, the country plans to start the renovation of 53,000 old urban communities, involving 8.65 million residents. According to the data reported by local statistics, from January to June, 42,600 old urban communities were newly renovated nationwide, benefiting 7.42 million households, and the operating rate was 80.4% according to the number of communities. In terms of provinces, the operating rate of 11 provinces including Guizhou, Hubei, Jiangsu and Inner Mongolia exceeded 95%.

Up to now, 24,000 kilometers of aging pipelines such as water, electricity and heat have been newly renovated, 12,000 elevators have been installed, nearly 300,000 parking spaces have been added, 10,000 charging piles for electric vehicles have been added, 3,200 community service facilities have been added, and nearly 2 million square meters of leisure and fitness venues have been added.

According to the relevant person in charge of the Ministry of Housing and Urban-Rural Development, the transformation of old residential quarters focuses on the urgent problems of the masses. Through the transformation, the living environment, facilities and service functions of old urban residential quarters and old communities have been improved, meeting the needs of the people for a better life, and also playing a positive role in strengthening and improving grassroots social governance. It is not difficult to find that after some buildings are equipped with elevators, the "suspended old people" who used to go downstairs for a year or so can often go downstairs to bask in the sun and chat with the old neighborhoods. Some old communities have implemented barrier-free renovation to create a "barrier-free and loving" travel environment.

The travel experience of the disabled, the elderly and pregnant women is smoother. After the renovation of some old communities, convenience service facilities such as breakfast shops, repair shops and side dishes stations have been added, and the fireworks in the old communities have returned.

The "Notice" makes it clear that we should vigorously transform and upgrade residential quarters (including single-family residential buildings) that were built earlier, were out of care and disrepair, had obvious shortcomings in facilities and had strong residents’ willingness to transform, and focus on transforming old urban quarters that needed to be transformed before the end of 2000. Encourage qualified places to study and establish the mechanism of "finding problems through physical examination and solving problems through renovation" in residential quarters, explore the establishment of housing pension and insurance system, solve the problem of "where does the money come from", and form a long-term mechanism for renovation and construction of residential quarters.

Effectively solve difficult problems

How will the transformation of old urban communities be further promoted? On the "ministerial corridor", Ni Hong proposed that the renovation of old residential areas should focus on "corridor revolution", "environmental revolution" and "management revolution". The "Notice" also proposes to carry out a comprehensive physical examination of the old urban communities to be rebuilt, and identify potential safety hazards and shortcomings in facilities and services. According to the physical examination results and residents’ wishes, according to the sensible, quantifiable and evaluable working standards, the content, scheme and construction standards of the renovation are reasonably determined by "one community, one countermeasure", and the problems of difficulties, blocking points and pain points strongly reflected by the masses are effectively solved.

According to the relevant person in charge of the Ministry of Housing and Urban-Rural Development, to promote the "corridor revolution" in a down-to-earth manner is to speed up the renovation of aging and hidden dangers pipelines such as gas, water supply, heat supply, drainage, power supply and communication, and to rectify pedestrian walkways, exhaust flues, ventilation shafts, up and down paths, etc. in the building, and to carry out the safety rectification of residential external walls. Vigorously promote the installation of elevators in conditional buildings. Focus on promoting energy-saving renovation of existing buildings.

To further promote the "environmental revolution", it is necessary to add parking and charging facilities, as well as supporting facilities such as health, sports and fitness according to demand. Focus on the transformation of old urban residential areas, promote the aging and child-friendly transformation of public space and supporting facilities in old residential areas according to local conditions, strengthen the construction of barrier-free environment in old residential areas, make overall plans for the construction of community service facilities such as old-age care, nursery and meal assistance, and improve the service function of "one old and one small" in old residential areas.

To effectively implement the "management revolution" means to establish and improve a joint meeting mechanism with the leadership of grass-roots party organizations, the cooperation of community residents’ committees, the participation of owners’ committees and property service enterprises, and guide residents to negotiate and determine the management mode, management regulations and owners’ rules of procedure of the reformed community to jointly safeguard the transformation results. Actively guide qualified old residential areas to introduce specialized property service enterprises, improve the mechanism of using special funds for housing, and promote the maintenance and renewal of old residential areas to enter a benign track after renovation.

In the process of renovation of old residential areas, the renovation of installing elevators has attracted much attention. In recent years, the number of elevators installed in existing houses has continued to increase, and it has also become the focus to solve the problem that it is difficult for residents of high and low floors to reach a consensus when installing elevators. On June 28th, the National People’s Congress Standing Committee (NPCSC) passed the Law on Barrier-free Environment Construction in People’s Republic of China (PRC), which clarified the principle that barrier-free environment construction should be combined with aging renovation, and supported the installation of elevators in existing houses.

According to the relevant person in charge of the Ministry of Housing and Urban-Rural Development, the Ministry of Housing and Urban-Rural Development will "actively promote the installation of elevators in existing houses with conditions" and solve the problem of "difficulty in installing elevators" in old communities. Residents will be guided to jointly agree on the design, construction, fund sharing and follow-up management and maintenance plan for installing elevators to protect the people’s right to know, participate and supervise. It will guide all localities to actively solve the problem of "one-vote veto" in the process of residents’ consultation through grassroots consultation, dispute mediation and civil litigation. Efforts should be made to install elevators in the form of flat floors to achieve barrier-free access, encourage elevator enterprises to develop elevator products and technologies that meet the needs of installing existing houses, and encourage organizations to purchase elevator equipment in a centralized manner, so as to strive for preferential prices, high-quality after-sales service and quality assurance for residents.

Focus on eliminating potential safety hazards

In the process of rebuilding old urban communities, security issues are also highly concerned. Due to its long history, all kinds of pipelines and facilities are relatively old, and it is easy to have more security risks. Safety accidents caused by obsolete pipelines and facilities have occurred frequently in recent years.

In this regard, the "Notice" requires that pipeline units and professional technicians should be organized to conduct a physical examination and evaluation of the safety status of old residential areas by subcontracting to the film and taking responsibility to the people, focusing on fire-fighting facilities and public parts such as building roofs, external walls and stairs, as well as various pipelines and pipelines, so as to comprehensively identify possible safety hazards in old residential areas. For the discovered safety hazards, it is necessary to determine the safety management and control and hidden danger remediation plans in different categories, and speed up the implementation of rectification as a priority transformation content, ensure that the aging and facilities and components with safety hazards should be completely changed, guide relevant technical institutions to do a good job in inspection technical support, and speed up the elimination of safety hazards around the masses.

At the same time, residents should further improve their safety awareness and strive to form a consensus on transformation. For example, the replacement of rubber hoses for gas users, installation of gas safety devices at the user’s end, maintenance and replacement of aging pipelines such as indoor gas and water supply and drainage of residents will be included in the renovation plan of old urban communities, so as to guide residents to do a good job in cooperating with the construction and jointly maintaining the renovation effect.

In addition, in the process of renovation of old urban residential areas, the main responsibility of project quality and safety of all parties involved in the construction should be compacted and the construction site management should be strengthened. Take targeted measures to accurately eliminate all kinds of construction safety hazards, and effectively prevent and contain production safety accidents such as falling from a height, hitting objects, and lifting machinery injuries. Optimize the site layout, reasonably arrange the construction sequence, strictly control the construction vehicles, and minimize the impact on residents’ lives. Resolutely crack down on behaviors that harm the interests of the people, such as cutting corners and substandard construction quality.

The Ministry of Housing and Urban-Rural Development said that it will work with relevant departments to strengthen coordination and cooperation, compact local main responsibilities, urge and guide all localities to focus on serving the people, facilitating the people and ensuring the people’s safety, implement targeted transformation, speed up the elimination of potential safety hazards, and comprehensively improve the living environment, facilities and service functions, so that old communities can also have modern functions, and constantly enhance people’s sense of acquisition, happiness and security.

After Guo Gangtang, the prototype of the movie "Lost Orphan", successfully recognized his relatives in July this year, Sun Haiyang, the prototype of the movie "Dear", also achieved a reunion on December 6, and met Sun Zhuo, his son who had been abducted for 14 years. The unexpected reunion in the movie has come true in reality, and such a touching story is also happening in Ningxia …

Since January this year, the Ministry of Public Security has deployed a nationwide "reunion" campaign. Ningxia Public Security Department, in combination with the study and education of Party history and the education and rectification of the political and legal team, clearly requires that the work of helping parents find their children’s "reunion" be a political task, so as to make the road of recognizing relatives shorter. As of December 13th, 46 separated families have been reunited, and 17 abducted or lost children in Ningxia have been recovered.

After 61 years of reunion.

"I’m so happy. I’ve been listening to my parents for a lifetime since I was a child, and I finally found it. Thanks to the comrades of the public security police, the parents’ wishes have finally been realized. " In June this year, 61-year-old Ge Jianchun, accompanied by the police of the Criminal Investigation Detachment of Yinchuan Public Security Bureau in Ningxia, and his family drove more than 640 kilometers from Yinchuan to Taibai County, Baoji City, Shaanxi Province, to reunite with his second brother Ge Minsheng who had been separated for 61 years.

This time, the road for brothers to meet each other has gone for 61 years.

Ge Jianchun recalled that in 1960, due to the work of his father Ge Yangqing, his parents separated the two places. The pregnant mother Tang Lanying took the eldest son Ge Ansheng and the second son Ge Minsheng and took the train from Lanzhou, Gansu Province to Xi’ an, Shaanxi Province. At that time, the environment on the train was noisy and there was a large flow of people. Tang Lanying had to be distracted to take care of two children. At that time, he accidentally lost Ge Minsheng. For 61 years, the family has never given up looking. This year, finally found it.

"Take off your socks and let me see." Ge Jianchun said this when the two brothers just met at the scene. Seeing that Ge Minsheng’s little toe exposed after taking off his socks has two petals of nails, he immediately choked and hugged him and said, "Yes, you are my brother, and our family’s nails are like this."

Ge Minsheng came to Yinchuan with his family during the "Eleventh" holiday this year. "Before my parents died, I was obsessed with my second brother, and my greatest wish was to find him. Now that our family is reunited, I believe they must be very pleased. " Ge Jianchun said. "After the holidays, our big family has become more lively."

Recognizing the "gold standard" is the final word.

Ge Minsheng, an old man who has been lost for 61 years, recognizes relatives with his family, which is the longest successful case of finding relatives in Ningxia since the reunion operation. DNA test, known as the "gold standard" for identifying kinship, is the decisive factor for the success of this search.

In the centralized comparison battle of criminal technology in the "Reunion" operation, through the sharing of national data resources, Zhou Dong, the second-level director of police technology in the Criminal Technology Department of Ningxia Public Security Department, found an important clue: Zhang Moumou (44 years old), a man in Taibai County, Baoji City, Shaanxi Province, was highly suspicious compared with Ge Shengyang, who was looking for relatives, and needed further verification. After learning this important clue, the police of Yinchuan Public Security Bureau immediately contacted Baoji Public Security Bureau of Shaanxi Province. With the help of local police, after some work, they successfully compared Zhang Cheng (66 years old), the father of Zhang Moumou, and identified him as Ge Minsheng, a child who disappeared 61 years ago.

"The comparison process is really tortuous. Although I keep failing, I always cheer myself up and try again. I am very excited at the moment of success." Zhou Dong explained that in theory, if there are DNA samples of parents and children in the abduction database, the system can automatically conduct accurate comparison. However, the reality is often complicated, which requires technicians to manually screen and compare from massive data.

After witnessing the recognition scene of the Ge brothers, Zhou Dong was deeply touched. "For a family, the loss of children and their relatives have a great influence. I am proud that my work can help make up for their regrets." Zhou Dong said.

In May this year, in order to carry out the "Reunion" operation in depth, the criminal investigation department of Ningxia Public Security Bureau set up 25 free blood sampling points for the "Reunion" operation in the whole region, and at the same time collected blood samples of unidentified persons and lost persons, tested DNA and entered them into the national abduction database.

"Thanks to the continuous expansion of the abduction database and the progress of DNA detection technology, the accuracy and efficiency of DNA comparison have improved, providing technical support for the’ Reunion’ action in Ningxia." Wang Yuru, the second-level director of police technology at the Criminal Technology Department of Ningxia Public Security Department, said.

Looking for clues in the world

In the process of finding relatives, the work of criminal investigation police is also very important. In the case of insufficient conditions for DNA identification samples, they need to look for clues in massive information; It is also necessary to organize family recognition, and cooperate with civil affairs, women’s federations and other relevant departments after family recognition to help abducted and missing persons integrate into their families and society.

In 2007, Zhang, who lives in Zhongwei, left home because of employment pressure and inner confusion, and has not heard from him since then. In the past 14 years, the Public Security Bureau of shapotou district, zhongwei attached great importance to it, and was responsible for the police to look for clues from the massive information and go to many provinces, cities and counties to check the clues.

On September 20th this year, when the "Reunion" special class of the Criminal Investigation Brigade of shapotou district Public Security Bureau combed the relevant information, it was found that the ID number of the missing person Zhang was the same as that of a man registered by the Shanghai Public Security Bureau in December 2020. After learning this information, Wu Haiyang, deputy head of the Criminal Investigation Brigade of the Bureau, actively docked with the Shanghai public security organs to find the blood card collected by the man during registration for DNA identification. After identification, the man and the Zhang couple are in line with the parent-child genetic relationship. Wu Haiyang and his colleagues immediately went to Shanghai to look for Zhang.

After arriving in Shanghai, with the support of the Criminal Investigation Bureau of Shanghai Public Security Bureau and Yangpu Branch, Zhang’s whereabouts were found. Wu Haiyang took out the photos and videos of his family life taken in advance, which were compared and confirmed by Zhang, and told him about the recent situation at home, and finally successfully persuaded Zhang to return to his family.

"As a policeman, it is commonplace to run around, but I feel that it is worthwhile to see their family reunited again." Wu Haiyang said.

It is understood that this year, the Ningxia Public Security System comprehensively sorted out the cases of local children being abducted since the reform and opening up, filed cases by case, re-examined the papers and found the families of abducted children to understand the situation, deeply searched for clues to solve the case, used new means of investigation, and used big data resources to tap the breakthrough point of solving the case. Check the incident one by one, re-study the nature, re-sort and judge the relevant information of suspicious persons suspected of trafficking crimes, and carry out the work of merging cases and digging deep into the remaining crimes. Among them, in February this year, the abduction case of Lin Mohao in zhongwei, which was supervised by the Ministry of Public Security, was successfully detected, the abducted child Lin Mohao was rescued, and three suspects were arrested, which achieved good social effects.

"We organized a number of police types to simultaneously file cases and work in the same direction, carried out joint consultation and judgment, and integrated technologies such as big data judgment and DNA testing and identification, actively explored, summarized and refined a series of effective technical warfare methods." Wang Cheng, the detachment leader of the Ningxia Criminal Investigation Corps and the head of the "Reunion" action class, said.

In the next step, the criminal investigation department of Ningxia will thoroughly practice the people-centered development thought, continue to carry out the practical activities of "I do practical things for the masses", use traditional and new media propaganda methods to deeply mobilize the support and participation of all sectors of society and the masses, and make in-depth use of data screening and comparison, criminal technology inspection and identification and other measures to let more missing abducted children, suspected abducted people and unidentified people go home for reunion.

Standardize the behavior of vehicle rescue service, and shall not force the designation of rescue agencies, and shall not hinder or prevent the third-party rescue agencies entrusted by the parties from entering the site for service.

　　(3) Strengthen passenger health services. Passenger stations, expressway service areas, and "driver’s home" business units should strengthen the reserves of medicines such as fever medicines, cold medicines, and first-aid medicines. If conditions permit, they can set up "health stations" or medical service points, and open up separate rest places to provide more warm family services for truck drivers and passengers in need.

　　(four) to ensure automobile maintenance services. Advocate the normal operation of Class I and Class II automobile maintenance enterprises and Class III engine specialized enterprises during the Spring Festival holiday.

The influent quality is an important basis for determining the process flow of sewage treatment plant, and is the main parameter for accounting the actual emission reduction, which directly affects the construction cost and operation cost. till/extremely2014A sewage plant was built in the urban area of a city in, with a designed treatment capacity ofeightten thousandm3,And equipped withfiveA lifting pumping station;The main purpose of the sewage treatment plant is to play an important role in reducing the total emission of major pollutants in the region. However, with the official operation of the sewage treatment plant, a series of problems are gradually exposed.,One of the most important problems is water inflow.CODThe concentration is generally low. In view of this situation,The author makes an investigation and analysis.,The following results are obtained.

oneMethods and contents of investigation

①Collect information.Contact relevant units to collect relevant information and understand the relevant situation.,Including the design and completion drawings of drainage pipe network in the service scope of sewage plant, urban population, meteorological climate and other information.;Drainage system adopted by the city, groundwater situation and pipe network maintenance, etc. Analyze the pipe network diagram in detail,Determine the sampling point in combination with field investigation.

②Carry out major pollutants on each drainage unit, including domestic sewage raw water, sewage interception head, branch pipes at all levels, sewage pumping station, etc.CODSampling monitoring of concentration.Select representative residential areas to investigate the treatment efficiency of septic tanks and the situation of residents’ own water.

③Investigate and analyze the regional drainage pipe network, including sewage pumping station and sewage interception engineering pipe network.According to the population and water consumption units in the service range of the pipe network, the theoretical displacement is estimated and compared with the actual displacement in the measured range to determine the pollution acceptance rate of the drainage pipe network.

④Find out the specific location where the external water source enters the pipe network, and record its flow andCODConcentration, and continuous monitoring for many days.

⑤According to the experimental results and collected data, the causes of low influent concentration in sewage plants are analyzed and summarized, and targeted suggestions and rectification measures are put forward.

2Present situation of actual inlet water quality of water supply and drainage and sewage plant in a city

According to the survey, the average water consumption of urban residents in this city is8.91ten thousandm3,The peak period of water use can reach near9.7ten thousandm3. Its drainage system is mainly intercepting combined system. The sewage treatment plant reflects the basic situation of the water quality of the sewage treatment plant on that day with the mixed samples of the early, middle and late inflow. Through the mixed inlet water of the sewage treatment plant in the morning, the middle and the eveningCODMonitoring the concentration, and obtaining the change diagram of the inlet water quality, as shown in the figure.l.

YoubiaooneAccording to the monitoring results in.,The concentration of sewage in residential areas and commercial dining areas is relatively high, while the concentration of sewage in hospitals is low, and the concentration of sewage in municipal central areas is similar to that in hotel-intensive areas. Calculate the domestic sewage according to the proportion of various domestic sewage.CODThe weighted average concentration is189.34mg/L.

fourcause analysis

4.1Problems of drainage system

The new urban area of this city adopts the complete rain and sewage diversion system.,However, the main sewage pipe has not yet been built.,Sewage can only be combined with rainwater pipes and discharged into the nearest river channel.,Polluted water environment;The drainage system in this city is mainly the combined system of rain and sewage. At present, the old city is still using the way of collecting sewage by culvert instead of pipeline. In addition, the city has a subtropical monsoon humid climate, with frequent rain and heavy rainfall in the rainy season. In recent years, the average annual rainfall in this city is about1800mm,This greatly increases the dilution effect of rainwater on sewage concentration. It can be seen that the rainwater and sewage confluence system has a great influence on the influent concentration of sewage plants.

4.2Exogenous lowCODInfluence of concentrated water source entering sewage pipeline

During the investigation, it was found that there were many foreign water sources entering the sewage pipe network in the whole sewage pipe network collection system. These foreign countries are lowCODConcentrated water sources include river water, swimming pool water, construction water and groundwater. The survey results show that the average amount of water flowing from the inner river into the pumping station reaches2.
2ten thousandm3,About the total sewage volume1/4,thatCODThe average concentration is60mg/L; There are small and medium-sized swimming pools in many communities in the city, and the water replaced by them is basically discharged into the urban sewage pipeline, just like the water used for construction.,These all feed the sewage plant.CODThe concentration has a certain impact.;Located in the south bank of the middle reaches of the Yangtze River, the city is rich in water resources and has a high groundwater level.,However, most drainage pipes are made of concrete pipes, even rigid joints in the old city. Therefore, groundwater and surface water can easily penetrate or flow into the drainage pipe network.,The concentration of sewage is dilute.

4.3Problems of septic tank setting

Septic tank is a simple decentralized facility for primary sewage treatment, which can play a certain role in sewage treatment. Therefore, when there is no sewage treatment plant in the urban area, septic tanks are built in many residential areas to treat domestic sewage.,To some extent, it can reduce the pollution of water. But after the sewage treatment plant was established,,The pipe network collected the sewage pretreated by septic tanks.,It also directly reduces the amount of sewage entering the sewage treatment plant.CODConcentration. The survey results show that the septic tank treatment efficiency of the whole residential area in this city is as follows35%about,Finally, the supernatant of septic tank is discharged into the sewage pipe network.

4.4Low pollution acceptance rate

Since the establishment of sewage treatment plant in this city,The laying of urban drainage pipe network is relatively backward.,Domestic sewage in many areas can’t be effectively collected to the main sewage pipe and discharged to the sewage treatment plant. In the urban area, some main pipes are still idle and not connected to the main pipe, and sewage collection pipes are not laid in many areas, thus reducing the effective collection area of the drainage pipe network and the low pollution acceptance rate. In some areas of the city, the main sewage is directly discharged into the nearby water body, so the amount of sewage to be treated cannot be reached.,The phenomenon of pumping river water to pretend to be treated, which not only leads to the low pollution acceptance rate of sewage plants and the low influent concentration, but also causes the pollution of environmental water bodies, which does not reflect the value of building sewage plants at all.

4.5Residents’ water use habits

With the continuous improvement of the city’s water supply system and the continuous improvement of residents’ living standards, the city’s water price is low and local residents’ awareness of saving water is not strong.,As a result, the per capita water consumption has increased year by year. According to the survey, the increase of residents’ water consumption is mainly reflected in the increase of water consumption for bathing and washing.,The organic matter concentration of these domestic sewage is low, which will inevitably lead to the low influent concentration after entering the sewage plant.

fivecounter-measure

5.1Pay attention to the preliminary investigation and planning and design of urban drainage system construction

The basic data of urban drainage system planning and design is the decisive factor to evaluate the planning and design quality and social and environmental impact. The main basic data include the overall urban planning, existing urban drainage systems and facilities, local sewage irrigation, and the status quo of sewage reuse. If the sewage plant does not adjust the sewage quality in the collection area, the current sewage pipe network in the collection area, the population and water consumption in the sewage collection area, etc.

Check and design, which will lead to the uncertainty of the quantity and quality of water entering the sewage plant after its completion.

5.2Improve the drainage system

According to the national drainage code, "different drainage systems are allowed in the same town", the intercepting combined drainage system can be used for transition in the near future, and the separated drainage system can be gradually transformed with the urban construction in the long term, and the original rainwater and sewage combined pipe can be changed into a single rainwater pipe.,No longer connected to the intercepting main pipe, at the same time, the intercepting main pipe is used as the sewage main pipe and its overflow port is closed, and the sewage branch pipe is paved again to connect to the sewage main pipe, so that in the long run,

The rain and sewage are completely separated. The building density in the old city of this city is high.,The laying of pipe network is also complicated, and it is difficult to transform. Therefore, areas that are easy to transform, such as areas with low building density and low pipe network density, can be transformed into a complete rain and sewage separation system first, and then combined with the planning department.,For the old city which is difficult to transform, the drainage system is gradually changed to the rain and sewage complete separation system.

5.3Reduce external water sources entering the pipe network

During the investigation, it is found that the external water sources entering the pipe network in this city mainly include rainwater, river water (including a large number of internal rivers entering the collection pool of pumping stations) and groundwater. Therefore, measures should be taken as far as possible to reduce the entry of foreign water sources into the sewage pipe network, and even to prevent river water from entering the pipe network. In this regard, the following measures are proposed:①The main measure to prevent rainwater from entering the sewage pipe network is to gradually change the drainage system into the rain and sewage complete separation system.; ②For several drainage outlets connecting the sewage pipe network and rivers in the urban area, as well as culverts serving as sewage main pipes to collect domestic sewage, under the condition of not affecting flood discharge,,It can be blocked to prevent rainwater and other low-concentration external water sources from entering the pipe network.;For the overflow port where river water is easy to flow backward, a suitable flap can be installed to prevent it from flowing backward. (3) do a good job of leakage prevention and impermeability. When designing urban drainage network, we should investigate the groundwater and surface water conditions in various areas of the city.,In order to do a better job of leakage prevention and impermeability, so as to achieve the purpose that the influent concentration of sewage plant is least affected by the infiltration of groundwater and surface water.

5.4Gradually transform septic tanks

If there is no septic tank, feces and other debris will directly enter the sewage pipeline, which will easily cause pipeline blockage, so it is not recommended to completely dismantle the septic tank.,Considering the influence of septic tank on the influent concentration of sewage plant, it can be reformed. Most communities or buildings in this city are equipped with three-stage septic tanks, which have many stages and long sewage retention time.,To reduce the ability of septic tank to treat organic matter, the number of stages can be reduced, and the retention time of sewage and anaerobic digestion time can be shortened.,A simple precipitation effect can be achieved. Corresponding measures can be taken to reduce the number of septic tanks and reduce the volume of septic tanks.

5.5Improve the construction of sewage pipe network and improve the pollution acceptance rate

The problem that often exists in urban sewage plants is that although the sewage plants are completed and put into operation as planned, only part of the sewage main pipes and branch pipes are built in the sewage pipe network.,Not all the sewage in the planned area is collected, resulting in insufficient actual treatment capacity of the sewage plant and the phenomenon that the uncollected sewage is directly discharged into the river to pollute the environment. The sewage treatment plant in this city also has similar problems, so it is necessary to re-plan the drainage pipe network to fully connect with the old drainage system.,Try to ensure that all sewage in the planned area will eventually be discharged into the sewage plant.

5.6Strengthen residents’ awareness of water saving,Improve water use efficiency

The city is rich in water resources, the water price is not high, the residents’ water consumption is increasing year by year, and the habit of wasting water is also formed, so it is particularly important to strengthen the residents’ awareness of water saving. It is suggested to start from the following two aspects.:①Do a good job in publicity, encourage residents to save water, and encourage residents to use more water, such as collecting water for washing vegetables and bathing as toilet water. (2) adjust the water fee or the planned water consumption is the same as the fixed water supply, and control the water consumption of residents, so that residents can gradually form the habit of saving water.

Link: Cao Yu’s witty remarks

　　The famous playwright Cao Yu said affectionately when talking about radio dramas:　

　　"The life of radio drama lies in its unique personality. The artists of radio dramas left the audience with a vast world, which enabled the audience to participate in the creation. The audience is the creator of the radio drama. Close your eyes and listen, all the characters, the endless changes of life, with magical language and sound, you don’t feel like spreading the wings of imagination and soaring in the mysterious world. "　

　　"I like to enjoy this art alone in a quiet night. It does have a special charm, which can touch people’s emotional depths, make people fly, and make our world turn into a myriad of vivid faces with closed eyes and listening. "　

　　Radio drama is a goddess of charm, like poetry and dreams, which makes people enjoy all the wonderful things in the sound world.

Researchers have designed a novel graft polymer shell for iron oxide nanoparticles, which can deliver anticancer drugs and realize real-time monitoring of drug release.

　　Recently, chemists at the University of New South Wales (UNSW) in Australia have synthesized a new type of iron oxide nanoparticles, which can not only deliver anticancer drugs to cells, but also monitor the release of drugs in real time. Researchers say this is an important progress in the field of nano-diagnosis and treatment. Related papers were published in ACS Nano, a journal of American Chemical Society recently.

　　"This kind of iron oxide nanoparticles can track and monitor drug delivery, which makes it possible to adapt to the individual differences of different patients." Cyril Boya, an associate professor at UNSW School of Chemical Engineering, said. Knowing how the anticancer drug delivered by nanoparticles is released and its influence on cells and surrounding tissues, doctors can adjust the dosage to achieve the best curative effect of the drug.

　　For a long time, magnetic iron oxide nanoparticles (IONPs) have been widely studied, but most of them are used as contrast agents in magnetic resonance imaging (MRI). Only recently have they been explored for drug delivery. At present, only a few studies have described how to load chemotherapy drugs on the surface of magnetic iron oxide nanoparticles, which can not effectively prove that they can really deliver drugs into cells, just some speculations. In this study, a new method was designed to load drugs on the surface of IONPs, and it was proved for the first time that these particles could deliver drugs into cells.

　　UNSW researchers fitted IONPs with a well-designed graft polymer shell, which made it show excellent colloidal stability in water and serum. Polymer shell can realize the reversible adhesion of doxorubicin (an anti-tumor drug) through imine bond, which provides a controllable release mechanism for doxorubicin in acidic environment.

　　Using a technique called Fluorescence Lifetime Imaging Microscopy (FLIM), researchers proved for the first time that IONPs can be easily accepted by two cell lines (MCF-7 breast cancer cells and H1299 lung cancer cells), and at the same time, the release of DOX in cells can be monitored.

　　"Usually, drug release experiments are only simulated in the laboratory, not in cells. This is very important. With cells, we can determine the dynamic movement of drug release in a real biological environment. " Boya said, "We have proved that workbench chemistry (referring to traditional chemical experiments without high-end equipment and computer models) can also be carried out in cells, and the next step is to enter the living application."

The heart is one of the most important organs for us, and its existence and health affect our body and life.
There may be many problems in the heart, among which heart failure often makes people talk about it. Heart failure is the abbreviation of heart failure, which refers to serious cardiac insufficiency, that is, the systolic and/or diastolic function of the heart is impaired. It is not a disease, but an abnormal state that affects the whole body, which is caused by the gradual progress and aggravation of other primary heart diseases, resulting in the loss of compensatory ability of cardiac function, which leads to the inability of the heart to bear the normal physiological blood pumping demand. Heart failure is a state, belonging to a kind of organ failure, which is formed based on the gradual aggravation of some heart diseases themselves, and is often the end-stage manifestation of heart disease. Can be acute onset, chronic development, but also divided into left heart failure, right heart failure and heart failure.

There are many causes of heart failure. Infection: viral myocarditis, infective endocarditis, etc. Myocardial ischemia or pathological changes: severe coronary heart disease, dilated cardiomyopathy, etc. The structure of the heart is abnormal: complex congenital heart disease, long-term heart valve disease and so on. Almost all cardiovascular diseases, even improper drugs and excessive mood fluctuations may lead to heart failure.

Heart failure will have different manifestations according to the priority: acute heart failure is dangerous, with typical sitting breathing and obvious symptoms; Chronic heart failure often has no characteristic manifestations at first, and it is often labor-induced dyspnea at first. When it is seen in mild physical labor, it has obvious dyspnea and palpitation discomfort, and then it will suddenly wake up and have difficulty breathing during quiet sleep at night. Left heart failure is characterized by decreased activity ability and even inability to complete daily self-care; Right heart failure often has depressed edema of the lower limbs, mostly located in the ankle. After pressing with fingers, the swollen skin will not rebound immediately, and a small depression will appear. This is because of poor blood return caused by cardiac insufficiency.

Heart failure is the process of heart disease progression and the manifestation of the end stage of the heart. Whether it is terrible depends on the primary disease and the degree of progress. Acute heart failure, like viral myocarditis, is often very dangerous, and it will be life-threatening if it is not treated in time. As long as chronic heart failure is treated as early as possible, those patients with mild or moderate heart failure can still get a better prognosis. As for the popular saying that "patients with heart failure can only live for five years, which is more terrible than cancer", there is no such saying. Early detection, early intervention and treatment of heart failure can still achieve a better prognosis. With the development of medicine, many measures to treat end-stage heart failure, such as heart transplantation, artificial heart and ventricular assist, are being applied in clinic, which will greatly improve the long-term survival rate of patients with heart failure.

So, how to reduce the risk of heart failure? Except for a few diseases that cannot be treated at present, such as dilated cardiomyopathy, in most cases, as long as they are treated in time, they will not develop into heart failure. Therefore, active treatment of primary heart disease is the primary means to improve the prognosis of patients. Patients with heart failure need to treat primary heart disease first. At this time, patients often have a serious primary disease, so standardized treatment is more needed. In addition, we should pay attention to the following aspects: avoiding colds and preventing infections; Pay attention to diet, water and sodium retention in patients with heart failure can alleviate the above symptoms by reducing sodium intake; Control the amount of drinking water and monitor the inflow and outflow. If the long-term inflow is greater than the outflow, the heart burden will be heavier and heart failure will be aggravated. Pay attention to rest and avoid overwork; Patients with heart failure can be properly treated with diuresis, but diuresis also needs to monitor electrolytes and maintain electrolyte balance, especially potassium ions; Regular follow-up, do not adjust drugs without authorization; If you have obvious symptoms such as chest tightness, breath holding, and inability to lie flat, see a doctor in time.
