《标准》为什么要对最大坡长加以限制?

答案

参考答案:

道路纵坡的大小和坡长对汽车的正常行驶影响很大,特别是长距离的陡坡对汽车的安全行驶非常不利。

主要表现在:爬坡行驶的速度明显下降,以至采用较低的档位克服坡度阻力而容易导致汽车爬坡无力,甚至熄火;下坡行驶制动次数频繁易导致制动器发热而失效。因此《标准》规定要对最坡长加以限制。

While going to the office, I found an old man lying by the side of the bus stop.He seemed very sick and poor.Instinctively.I gave him some money.After a few minutes, I realized that he was probably too sick to get up and buy something with that money.I was thinking about how to help him when my bus arrived, halting my brainstorm.I quickly got on and rode off.

However, that night I couldn't sleep.I felt very angry at my own heartless and selfish behavior.How could I just walk away from that man without a thought for his suffering? I felt restless and very upset. The next morning, while waiting at the bus stop, I hoped to run into him again.But he wasn't there.I thought he may have gone to the sidewalk to sleep for the night.I looked around for him, but he had disappeared.Disappointed, I decided to check for him again on my way back.

While returning from work that day, I came back to the bus stop and resumed my search for him. Thankfully, he was there.I quickly went to a nearby store and got him a blanket, some bread, and biscuits. When I handed them to him, he seemed very grateful."Now I will be safe from the cold," he smiled. I also gave him some more money and told him to keep it safely.After being able to help him, I felt very at peace.
