朋友，你注意到了吗？汽车的后窗往往打不开。那么，为什么各种车辆的后窗都打不开是死窗户呢？ 原来，这与空气的流动有关。 每一物体总要占据一定的空间，人也不例外。每个人占的地方，空气总要被人体所排开，但是人的体积比较小，行动又不像汽车那样快，所以人在行动 Friends, did you notice it? The rear window of the car is often not open. Why, then, why is it that dead windows do not open in the rear windows of various vehicles? It turned out that this is related to the flow of air. Every object always occupies a certain space, and people are no exception. Where everyone occupies, the air is always to be excluded by the body, but the size of the person is small and the action is not as fast as the car, so people are in action.
