Central Bangkok to Chinatown
Today (March 2), the Beijing Conference Center ran into Ding Lei, a member of the National Committee of the Chinese people's Political Consultative Conference. He was wearing Adidas casual clothes, smiling, looking very relaxed
when talking about the snow village incident in Northeast Asia, which caused great repercussions among entrepreneurs last year, Ding Lei said that he had not been to Yabuli. Ding Lei believes that a good business environment is crucial to the development of enterprises. In the Internet instry, the government generally gives strong support, but from another perspective, the situation is different. Ding Lei, for example, said that he is still raising pigs, and there are still many restrictions and restrictions in the field of agricultural high technology. A few years ago, pig raising required more than 100 chapters. Environmental impact assessment and other assessments, as well as laws and regulations, are difficult for ordinary people to enter, Now this situation still needs to be improved
Ding Lei also took the initiative to talk about the problem of recing the burden of middle school students. A few days ago, the Ministry of ecation and other four departments jointly issued a notice, deciding to carry out special governance actions for off campus training institutions to effectively rece the extracurricular burden of primary and secondary school students. Ding Lei believes that the original intention of this policy is good, but it can not be applied across the board in practice. It's good for children to develop more hobbies or watch TV as soon as they get home“ I have children myself. If I don't watch them for an hour, I will definitely go to watch TV. " Ding Lei believes that as long as children don't aim for exams, they should be encouraged to develop some hobbies after class(1) fuel system failure.
(2) excessive fit clearance between engine cylinder liner and piston, serious air leakage in valve train.
(3) abrasion of diesel pump plunger or fracture of oil outlet valve spring.
(4) road problem, The debugging motor is damaged.
(5) mismatched fuel is used. Different fuel should be selected according to different working environment for excavator operation, for example, the diesel with higher viscosity should be selected in winter, and the diesel with lower viscosity should be selected in summer.
(6) the power of excavator battery is insufficient or the battery line joint is loose.
(7) the excavator engine cylinder pressure is insufficient, The engine valve is not closed tightly.
(8) excavator solenoid valve fault.
(9) excavator fuel injection pump is insufficient. Generally, after the excavator stops, the fuel in the fuel injection pump will return to the tank, and there is no fuel in the fuel injection pump, so it is difficult to start.
(10) in addition, it is easy to start the excavator in winter, Therefore, when the excavator works in winter, it is generally necessary to preheat the excavator in advance. If the excavator still can't start after using the preheat function, the problem can be solved by spraying the starting fluid, but the starting fluid can't be used more. The generator is faulty and the starting motor is faulty.
2, In general, it is caused by the failure of the excavator oil pump or oil nozzle. The common treatment method is: pour the oil pump with cold water. If it can start smoothly, it indicates that there is a problem with the oil pump. It is necessary to calibrate the oil pump and check the oil nozzle. If it can't start smoothly, it is necessary to check the cause of the above-mentioned cold start failure step by step
On March 2, when answering the Shanghai Stock Exchange reporter's question on whether he is willing to go back to the A-share market, he said at the CPPCC press and Publication Committee station, "of course we will consider it."
Ding Lei said: "for a market in preparation, it can be listed at any time." At present, the CSRC is supporting the development of "new economy" in accordance with the spirit of the 19th CPC National Congress. It is clear that regulators are trying to promote IPO reform and keep the second batch of "batj" enterprises. In addition, the recent 360 return to a shares, Foxconn IPO special approval and other measures to open a green channel for "unicorn" enterprises all show that the regulatory authorities have made preparations in relevant aspects 
he said that blockchain technology is a decentralized account technology, and artificial intelligence has a higher level of breakthrough. China has a very broad market space in these two technologies, which can greatly improve efficiency. For example, blockchain technology contains an intelligent classification technology. If biometrics are added, it will be a very good personal credit system
in response to the recent capital speculation on blockchain technology, Ding Lei said that blockchain is only technology, but technology itself has no problem, and technology itself has no harm if it is hyped“ However, we can't use the name of technology or gimmicks to cheat. "
Ding Lei told the Shanghai stock exchange that he has prepared three proposals this year, involving children's and youth ecation, pension and medical health Among them, the youth ecation is Ding Lei's most concern“ Young people are the future of the country, "he said. At present, the best ecation resources in China are concentrated in the first and second tier cities, while the third and fourth tier cities and other rural areas are very scarce Ding Lei said that he hopes that through Internet technology, high-quality ecation can be delivered to every corner of the country. In this regard, we must consider the use of artificial intelligence technologyHello, there are the following reasons: first, the battery is aging or out of power
in order for the engine to run normally, several conditions must be met at the same time: fuel, air and starting energy
so we often encounter the fault that the car can't ignite normally. In most cases, it is caused by the lack of electricity, that is, the battery loses power
e to the low intake air temperature in the cylinder, the fuel atomization in the cylinder is not good, if there is insufficient ignition energy, it is easy to cause the phenomenon of cylinder flooding, too much fuel will accumulate in the cylinder, exceeding the ignition limit concentration and unable to land
PS: the ignition limit concentration is a range, but it is not a value. It can only be ignited within this range, even if it is too high or too low
in case of this problem, you can check whether there is oil stain between the spark plug electrodes. If it is cleaned, it can be ignited after it is installed. The thorough way is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, high voltage wire state, etc
Third, the exhaust pipe freezing is easy to occur in winter, when the weather is cold and the temperature is lowfor those car owners who are close to their home, their car use frequency is relatively low, and the water vapor generated by engine combustion freezes on some parts of the exhaust pipe, while the heat of short distance driving is not enough to melt the ice, and more ice forms after a night, which will affect the start-up and exhaust of the vehicle after a long cycle
so the car can't be saved. Don't put it in the corner all the time to eat ash, so the car condition will be worse and worse
In addition, the reasons for not starting the fire in winter may also be the addition of water or low-quality antifreeze, which may cause the waterways to be frozen or even the engine to be cracked, and the car water pump can not work and cannot start the fire I hope I can help you~many of the causes of ignition failure are caused by improper operation, such as no oil, no power, wrong gear, and these are quite common
1. No oil. I went out to rescue a car before, and the fuel gauge showed that it was below the red line, so naturally it couldn't catch fire
2. The battery is dead. It may be e to a long time without turning off the headlight and other reasons, or the battery life has expired. It is generally recommended to replace the battery in three years. In addition, the installation of xenon headlights, high-power audio, DVD, etc. is also the cause of vehicle circuit failure. It's easy to check if the car has no electricity. Just press the horn
3. Wrong gear. When the automatic stop car starts, the gear must be placed in P or n gear. If it is placed in R or D gear, it will not start. There are also some manual cars that can't catch fire if they don't step on the clutch<
Second, how to deal with the reasons why the car can't catch fire and the solutions
reasons for the use of the car: improper oil, no antifreeze, too much carbon deposit
in addition to eliminating the causes of improper manual operation, there may be motor failure, or oil pump supply, nozzle problems, sensor failure, etc. in case of these more complex situations, professionals need to deal with them. But usually pay more attention to the following, can avoid the emergence of these complex conditions
1, oil procts. When I was repairing a car, I found that there was water and mud in the oil tank. With this kind of oil, it was impossible for the car not to break down. So remind must go to regular gas station refueling, go out can take a gauze bag in the muzzle of the refueling gun, filter impurities
2, without antifreeze. Some car owners add water or low-quality antifreeze to their cars. As a result, when it is very cold in winter, the whole waterway is frozen and the engine is cracked. As a result, the water pump of the car can't work, it can't catch fire, and other parts of the engine are injured
3. Too much carbon deposit on the vehicle will also cause the vehicle not to start. The solution is to run at high speed frequently to rece carbon deposit. In addition, there's a trick for not starting a fire. Before starting a car, turn the key to the on switch, then turn it back, and then turn it on to the strat switch to start a fire. Let the computer run, calculate the water temperature and the appropriate air intake, and the ignition will be more smooth.

This is the E96 chip resistor. The mark on it is 01d, which means the resistance value is 100k Ω Kiloohm), as shown in the yellow highlight below
Ordinary set cannot be used, because dict requires that the key must be an immutable object, such as an integer or a string. Set list and other objects cannot be used because they can be modified (elements can be added or deleted). If you must use set, you must use frozenset. As the name suggests, after defining frozenset, you can't make any changes. For example, the following code can work with frozenset, but if you define it as set, it will fail
a=frozenset([1,2,3])
d={}
d[a]=100
