Whether there is the same intrinsic cause for failure and charity failure

That is, the result of a public welfare activity does not benefit the public, and the final benefit is individual departments or even private individuals.

The so-called public welfare loss is the failure of public welfare, which is specifically the loss of public welfare behavior. People's recognition of public welfare behaviors has decreased, the role of public welfare behaviors in society has decreased, or public welfare behaviors have been distorted and deformed.

How is it malfunctioning, is the central control still, the key can not be detected.

This basically doesn't happen, the brakes fail. Yes The hose bursts suddenly if it is not replaced for a long time, or the brake master cylinder is broken, and it is fine after the first foot is not braked. If the direction fails, the lever head falls off. Or the ball head of the direction machine falls off. Dysdirection is unlikely.

There are many reasons for brake failure, one is the lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, vacuum booster pump failure, excessive dirt of brake oil or air resistance after the mixed use of several brake fluids, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the gas tank or pipeline interface; The second is the failure of the parts due to improper operation, such as long-term downhill will cause the brake pads to rub and heat, the brake hub to carbonize, and the brake function to completely fail; Third, due to serious overload, under the action of gravitational acceleration, the inertia of vehicle movement is increased, which directly leads to brake failure. What should a novice do if the brakes fail while driving? 1.

Control the direction according to the road conditions and vehicle speed, disengage the high-speed gear, and at the same time quickly empty the fuel and shift the high-speed gear into the low-speed gear. In this way, the engine will have a lot of traction resistance and the speed of the vehicle will be reduced rapidly. In addition, the handbrake should be used in conjunction with the low-speed gear shift, but it should be noted that the handbrake should not be tightened or pulled too slowly.

If it is pulled too tightly, it is easy to make the brake disc "lock", and it is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will wear and ablate and lose its braking effect. 2.Use the bumper, carriage and other rigid parts of the car to rub and collide with natural obstacles (rocks, trees or soil slopes) on the side of the road to achieve the purpose of forcibly stopping and getting out of danger, and reduce the accident loss as much as possible.

3.If the brakes fail when going uphill, you should reduce to the middle and low gear in time to maintain enough power to drive up to the top of the hill and stop. If you need to park on a half-slope, you should keep the forward low gear, tighten the hand brake, and the personnel with the vehicle should use stones, skids and other objects to jam the wheels in time.

If there is a backward slippage, the rear of the car should face the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind. 4.When the downhill brake fails and the speed of the vehicle cannot be controlled by the mechanism of the vehicle itself, the driver should decisively use natural obstacles, such as rocks and trees on the side of the road, to cause resistance to the car.

If you can't find a suitable terrain or object to use for a while, in an emergency, you can move one side of the car closer to the side of the mountain, and gradually reduce the speed of the vehicle by rubbing to increase the resistance. 5.When the vehicle is descending a long slope or a steep slope, the vehicle should apply the brakes regardless of whether there is a situation or not.

It can not only test the performance of the brakes, but also buy time to control the speed of the vehicle when the brakes are found to be out of order, also known as predictive braking.

The keyboard is hardware, all have a service life, some keys are damaged is normal, if you often text input, you can choose a mechanical keyboard with better quality and feel, the key life can reach 50 million times, not the general membrane keyboard is comparable.

Keyboards are used a certain number of times, and if they exceed the number of times, they may not work.
