Answer: The classified kitchen waste is basically treated by crushing, direct discharge, landfill, fertilizer treatment, feed treatment, energy treatment and anaerobic treatment.

　 　 　 　1. Crushing. For this type of household garbage, due to the limited kitchen space, on-site reduction treatment is the basic foothold of kitchen waste treatment. The kitchen waste treatment device is arranged in the kitchen, and the crushed kitchen waste is discharged into the sewer network, mixed with water and then put into the urban sewage treatment system for harmless treatment, so as to achieve the purpose of harmlessness.　

　 　 　 2. Landfill. Because the kitchen waste contains a large number of degradable components, the stability time is short, which is beneficial to the recovery and use of the landfill site, and the operation is simple.

　 　 　 3. Carry out fertilizer treatment. Fertilization treatment methods of kitchen waste mainly include aerobic composting and anaerobic digestion. Aerobic composting process is to decompose organic solids into soluble organic substances by extracellular enzymes secreted by aerobic microorganisms under aerobic conditions, and then infiltrate into cells, and realize the whole composting process through microbial metabolism.

　 　 　 4. Feed treatment. The principle of feed treatment of kitchen waste is to use a large amount of organic matter contained in kitchen waste, and after crushing, dehydration, fermentation and soft and hard separation, the waste will be transformed into high-calorie animal feed, turning waste into treasure.

　 　 　 5. Carry out energy treatment. The energy treatment of kitchen waste mainly includes incineration and thermal decomposition. Incineration method has a high efficiency in treating kitchen waste, and finally produces about 5% residue which is convenient for disposal. Incineration is carried out in a special incinerator, and the generated heat energy can be converted into steam or electric energy, thus realizing the recycling of energy.

　 　 　 6 kitchen waste should be provided to specialized processing units for processing. It is strictly forbidden to use waste edible oils (including gutter oil) as edible oil after processing, to directly use kitchen waste to raise livestock and poultry and fish, and to use kitchen waste without harmless treatment to produce fertilizer.

　 　 　 7. Carry out anaerobic treatment process. After pretreatment, the kitchen waste produces crude oil and organic slurry, and the organic slurry enters an anaerobic fermentor for fermentation to produce biogas, which is purified and used for power generation and boiler heating.

　　As of January 27, 2018, the economic data of 31 provinces in 2017 have all been released, and the ranking of GDP and growth rate has also been clearly presented.

　　The Paper combed the statistics and found that compared with the same period in 2016, the top ten provinces in GDP last year did not change, and Chongqing surpassed Tianjin in ranking.

　　In terms of GDP growth, Guizhou and Tibet continue to lead the country with double-digit growth rates, while Tianjin’s growth rate has dropped sharply, while Liaoning’s growth rate has turned from negative to positive.

　　In 2017, Guangdong and Jiangsu ranked in the top two in the country with a total GDP of more than 8 trillion yuan, and the provinces ranked third to tenth were Shandong, Zhejiang, Henan, Sichuan, Hubei, Hebei, Hunan and Fujian. This ranking is consistent with that in 2016.

　　After Fujian, Shanghai’s GDP last year also exceeded 3 trillion yuan, reaching a new level.

　　Liaoning did not fall as predicted before. Last year, Liaoning’s GDP totaled 2,394.2 billion yuan, still ranking 14th in the country.

　　Up to now, the total GDP data of last year has not been released in Inner Mongolia. However, according to the 4%GDP growth rate announced by Inner Mongolia, it is difficult for the total GDP of Inner Mongolia to exceed 2 trillion yuan last year, and it will not be able to keep the 16th place in the country in 2016.

　　On the other hand, in 2017, the ranking of Chongqing’s total GDP has advanced. In 2017, Chongqing achieved a regional GDP of 1,950.027 billion yuan, which was 90.489 billion yuan more than Tianjin’s total GDP of 1,859.538 billion yuan last year. It is inevitable to overtake Tianjin in ranking.

　　In fact, in 2016, the total GDP of Chongqing has approached Tianjin. After the revision, the total GDP of Chongqing in 2016 was 1,774.059 billion yuan, and that of Tianjin in 2016 was 1,788.539 billion yuan, with a gap of only 14.48 billion yuan.

　　Tianjin’s growth rate declined, and Liaoning turned from negative to positive.

　　From the perspective of GDP growth rate, among the 31 provinces, a total of 8 provinces’ GDP growth rate last year was lower than the national GDP growth rate, including Beijing-Tianjin-Hebei and Northeast China. Tianjin’s GDP growth rate has dropped sharply, from 9% in 2016 to 3.6%, and it is now tied with Gansu.

　　This number has increased compared with 2016. In 2016, only Heilongjiang, Shanxi and Liaoning provinces were lower than the national GDP growth rate.

　　However, Liaoning’s GDP growth rate achieved positive growth last year, which is the best result since "squeezing water" in 2015.

　　According to the data of the work report of Liaoning provincial government in 2018, according to preliminary accounting, the regional GDP of Liaoning province last year was 2,394.2 billion yuan, up 4.2% over the previous year. Since 2011, the situation of one-way decline in economic growth has changed.

　　Last year, the top two GDP growth rates were Guizhou and Tibet, both of which achieved double-digit growth. Last year, Chongqing’s GDP growth rate dropped below double digits for the first time in 10 years, but it still ranked fourth in the country after Guizhou, Tibet and Yunnan with a growth rate of 9.3%.

　　Guizhou, Tibet, Chongqing, Yunnan, Jiangxi, Anhui and Fujian, which were among the top ten growth rates in 2016, remained on the list this year, while Tianjin, Henan and Hubei were squeezed out of the top ten. Sichuan, Hunan and Shaanxi have entered the top ten GDP growth rates, with GDP growth rates above 8%, all of which are central and western provinces.

At present, car dealers all understand the truth that they will face failure if they don’t build a car with their heart, and all kinds of new cars and good cars are born, which makes people overwhelmed. "Xiao Gang Bao" Sekelon RZ3S is so powerful that it can’t be stopped. Honda CBR1000RR, which is "not inferior to KTM in grade", has a higher and higher status, which makes people eager for it and is extremely envied by opponents. In today’s emphasis on spiritual enjoyment, only models that truly understand the requirements of car owners can stand. For example, this Kawasaki NinjaH2SX I mentioned is a first-class travel run in Kawasaki! Four-cylinder water-cooled 998cc, 200km with full oil, 280,000 is expensive.

Kawasaki NinjaH2SX is a top-notch motorcycle touring run that Kawasaki strives to build. Relying on its scientific and technological design, it takes the knight’s appearance as the starting point to highlight his temperament, so it can occupy the market in a short time. However, with the continuous progress of the times, the requirements of knights for buying a car vary widely, such as speed increase, steering, durability, atmosphere, etc. Only relying on a single advantage project, motorcycle brands will certainly not make great progress. With rave reviews, can other aspects of its performance meet the requirements of the knights, regardless of its attached design with a sense of science and technology? Do other aspects have advantages? Let’s analyze the core motorcycle of Kawasaki-Kawasaki NinjaH2SX.

Externally, the shape design covers a variety of fashions, and several lines of the front, rear and door frames are handled in place, which meets the aesthetic needs of Chinese people. The whole front of the car highlights the domineering style, rendering the noble atmosphere, and the slender lines of Chu waist highlight the strong impact. From the tail to the front of the car, it is a dive posture, giving people a strong sense of movement. The headlights are also biased towards the traditional design, and so are the turn signals. The matching of LCD screens can display more and more comprehensive information. The reflector is novel in configuration and has certain jitter buffering effect. The rims make the whole vehicle look fuller and more powerful.

In terms of power and actual driving experience, the engine is remarkable. The four-cylinder water-cooled design achieves a displacement of 471cc, and an efficient and stable EFI fuel supply is adopted. The maximum torque can reach 137 Nm, and the output power is relatively strong, with a peak power of 147KW. The transmission system adopts 6-speed step-by-step transmission chain, which changes gears very timely and smoothly. In addition, Kawasaki has world-class training skills, and the shift transmission and power output gradually run in to reach a tacit understanding. When the throttle is deeply screwed, there will be a steady stream of power, which will undoubtedly bring the owner a top-level driving experience. On the whole, the power of Kawasaki NinjaH2SX is still very competitive.

The measurements reached 2135x775x1205mm, the seat height was 835 mm, and the affinity was still lacking. The car body was 130mm from the ground, and it was not a problem to encounter speed bumps and potholes. The wheelbase was 1480 mm, and the distance between the front and rear seats of the car was reasonably optimized. As far as comfort is concerned, Kawasaki NinjaH2SX can be said to have reached the leading level of its kind. The driver’s seat cushion is slightly sunken, the cushion is generous and comfortable, and it doesn’t hurt when driving for a long time. The first-class suspension with shock absorption is adopted, which has good road control ability. When walking on irregular roads, it can bring a smooth and shock-absorbing experience like a four-wheeled car.

With regard to fuel consumption, engines can save motorists a lot of money on gas. Starting and stopping often in urban areas, the fuel consumption is only 6.82L, and the fuel consumption on roads can be as low as 5.64L/100km. Combined with the mass of the car body itself of 256KG, and the volume of the fuel tank reaches 19L, it is admirable that Kawasaki NinjaH2SX can have such fuel consumption data.

Manipulation is a veritable advantage of Kawasaki NinjaH2SX, with moderate handle thickness, light and flexible steering and good grip. The chassis is inclined to move, firm and solid, and will not shake loosely when turning. Overall, the handling performance is not lost to similar models.

Through the above analysis, as a popular car series, Kawasaki NinjaH2SX not only relies on the well-known appearance, but also has the same ability in handling and power, which can meet the needs of riders. At the same time, there are all kinds of configurations, so the price-performance ratio of Kawasaki NinjaH2SX is obvious in its class. So what do you think about motorcycle-Kawasaki NinjaH2SX?

　　(Reporter Dai Lili) Recently, the national social insurance public service platform was put into trial operation, and the insured can calculate how much pension they can receive in the future.

　　The website of the national social insurance public service platform is http://si.12333.gov.cn. The platform can provide social security annual enrollment information inquiry, treatment qualification authentication, pension calculation, social security relationship transfer inquiry, remote medical inquiry, overseas exemption application, social security card and electronic social security card status inquiry, etc., all of which are national and cross-regional services.

　　The website platform provides two registration methods, one is according to the ID number, and the other is according to the social security card and social security bank card.

　　Many people are puzzled that they have to pay hundreds or even thousands of dollars a month to pay the old-age insurance, but how much will they get when they retire in the future? Can "capital" be recovered? People really want to make a "one-click generation" through a ready-made calculation program to know the amount of their retirement pension. However, the prediction of pension is very difficult, the calculation formula is extremely complicated, and it is closely related to variables such as social wage, personal wage and interest rate. Under the condition that these factors are still unknown, it is almost impossible to calculate pension. Therefore, many calculators that can be searched online only calculate the payment amount, and it is difficult to find one that can accurately estimate the pension benefits. The official measurement service provides convenience for people.

　　It is reported that the platform will first provide the functions of social security annual enrollment information inquiry, treatment qualification authentication, pension calculation, social security relationship transfer inquiry, medical consultation in different places, overseas exemption application, social security card and electronic social security card status inquiry, etc., to achieve nationwide cross-regional services.

　　illustrate

　　Zhang, female, 35 years old, retired at the age of 55, and has paid for 11 years. "Average contribution wage index in previous years", in layman’s terms, is the ratio between one’s own salary and the social average salary. Because Zhang’s monthly salary level is generally about twice the social average salary, this index is assumed to be "2". At the end of last year, the personal account deposit amount can be found in her social security statement. Zhang’s current deposit amount is 107,519 yuan, and the "average monthly salary of employees in Beijing last year" is 7,855 yuan.

　　Then you need to fill in two forecast information: "average wage growth rate of employees in the future" and "future personal account bookkeeping rate". Because the average wage growth rate of employees released by Beijing Municipal Bureau of Statistics in recent years varies from high to low, reaching close to 18% at high time and just over 4% at low time, the "average wage growth rate of employees in the future" here is assumed to be 8%. "Future personal account bookkeeping rate" refers to the interest generated by the accumulated storage amount of personal accounts of endowment insurance. This bookkeeping interest rate should be determined with reference to the local average wage growth rate of employees in the previous year, the bank’s resident time deposit interest rate, the actual income from the operation of the endowment insurance fund and other factors. For example, the annual bookkeeping interest rate in 2016 is 8.31%, and the annual bookkeeping interest rate in 2017 is 7.12%. Let’s assume that this figure is 8%.

　　After all this information is input, the system gives the pension budget results. Zhang will retire in 2039, and his basic pension is about 19,123 yuan, including 9,702 yuan for basic pension, 9,421 yuan for personal account pension and 0 yuan for transitional pension.

　　It must be emphasized that these calculations are only made under the simulation hypothesis of multiple variables. The actual amount shall be calculated by the local social security agency at the time of retirement.

Flexible sensor material sample diagram

　　A flexible sensor with a thickness of 200 microns (one tenth of the normal blood vessel thickness) is made of a special force-electricity conversion biomaterial and wrapped around a blood vessel or a heart, so that the subtle changes of the whole body blood pressure of the cardiovascular system in the early, middle and late stages of thrombosis can be clearly recorded on peripheral devices such as mobile phones, and at the same time, the slight differences of the cardiovascular wall pressure caused by the alienation of tissues and cells at the initial stage of the disease can be reflected more accurately and in real time.

　　The reporter of Science and Technology Daily recently learned from Nanjing University of Science and Technology that Professor Feng Zhangqi’s research group has created a new method for advanced prediction and real-time follow-up of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall. At present, the research group has made phased technological breakthroughs and completed the evaluation of animal clinical medicine. Related research was recently published in American Chemical Society-Nanomaterials and Devices, a top international journal in the field of nanotechnology and nanodevices.

　　New Nano-materials for Efficient Biomechanical-Electrical Conversion

　　Cardiovascular disease is the "number one killer" threatening human health, and whether the blood vessels are unobstructed is related to the normal operation of the whole cardiovascular system. Thrombosis is a small piece formed by blood flow on the surface of the inner surface of a blood vessel where it is peeled off or repaired. In the variable fluid-dependent type, thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells.

　　Experts say that "advanced prediction" and "real-time follow-up after operation" of cardiovascular diseases are the key points for effective clinical diagnosis of such diseases, especially for patients with severe cardiovascular diseases such as vascular tumor resection, intracardiac stent, valve, vascular replacement and intravascular stent. However, the existing molecular screening and imaging techniques lack accurate specific recognition function, which makes the advanced prediction and real-time tracking of cardiovascular diseases become a worldwide technical problem in clinical diagnosis and treatment.

　　Feng Zhangqi’s research group has long been committed to the development of bioelectronic materials and nano-devices, trying to build a new method for advanced prediction and real-time tracking of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall.

　　According to Dr. Li Tong, the first author of the paper, this time they pioneered a flexible nanofiber material with high-efficiency biomechanical-electrical conversion performance. Its thickness is only 200 microns, and it can accurately sense the pressure change and then show it in the form of voltage.

　　The material is rich in electromechanical conversion dipoles, which can generate a voltage of 1154 volts per cubic centimeter under the action of only 1000 Pascal, and has excellent stability, sensitivity and biocompatibility.

　　After being implanted in the body, the cardiovascular system can be monitored in real time through the mobile phone.

　　Based on this, the research group designed and manufactured a flexible implantable pressure sensor. They implanted the sensor into the peripheral blood vessels and heart parts of experimental animals (adult pigs), which not only clearly recorded the subtle changes of systemic blood pressure in the cardiovascular system at the early, middle and late stages of thrombosis, but also output a more accurate pressure signal, reflecting the slight difference of cardiovascular wall pressure caused by tissue and cell alienation at the initial stage of the disease in real time.

　　"Normal people’s blood pressure is beating with frequency, but when some tissues or cells are alienated in blood vessels, a fluctuating signal will be generated on the detector, no matter whether it is getting bigger or smaller, it is disordered. Once we detect this disordered signal and it doesn’t match the signal stored internally, we will issue some warnings, indicating that blood vessels may have problems." Feng Zhangqi said.

　　In the future, the flexible sensor can be implanted in the body together with cardiovascular surgery. Through the introduction of wireless signal transmitter, medical staff can track and diagnose the pathological changes of patients’ cardiovascular system in real time at clients such as mobile phones.

　　Feng Zhangqi explained: "We can convert it into an electrical signal that can be output by remote sensing. In the future technology, we can transform it into a signal received by a mobile phone. After receiving the signal, the mobile phone can share this signal with the hospital, so that it can be monitored remotely in real time."

　　At the same time, the successful development of this ultra-sensitive flexible implantable pressure sensor also provides a new method for accurate detection of micro-stress in vivo, which has great technical promotion for clinical real-time and accurate measurement of craniocerebral pressure, renal pressure and intraocular pressure.

　　[car home New Car Launches] On August 16th, the pagani Roadster was officially released at the Pebble Beach Auto Show, with the same power configuration as the hardtop version, with a global limited edition of 130 V12 engines and an overseas price of 3.4 million US dollars, about 24.654 million yuan.

　　Although the new car is a convertible version, the net weight of the car body is the same as that of the hardtop version, both of which are 1280 kg. The design of the convertible structure part is ingenious, and it can be completely disassembled with a skylight. Not surprisingly, the new car adopts carbon fiber single shell body, and continues the traditional design of butterfly door with upward folding, which is highly recognizable. The front engine room cover is smooth without too many curves. The headlight group continues to adopt the traditional double-willow shape, and the interior decoration part of the headlight also uses carbon fiber. In addition, the air inlet of the front face is designed to be large, which makes the new car have strong heat dissipation ability.

　　The rear half of the car body uses an integrated rear cabin cover, and there is an observation window at the engine, so you can enjoy the V12 engine from AMG at any time. In the rear part, the classic central four-outlet exhaust pipe divides the color matching spoiler into two parts, and the taillights on both sides are arranged vertically. The overall hollow shape of the rear part is obvious and very layered.

　　The interior continues the style and layout of the pagani supercar interior. There is no central control electronic screen, all physical buttons are decorated with a circle of blue lights, and almost all parts of the car are covered with leather or carbon fiber panels.
