So what I'm doing is measuring from the bottom of one image to the bottom of the next image, about a fifth of a second later, like that. And they're getting faster and faster each time, and if I stack these guys up, then we see the differences; the increase in the speed is constant.
我现在就从一个照片的底部 丈量到下一张照片的底部 这是五分之一秒的间距 并且会变得越来越快 要是我们把它们堆起来 就可以发现 速度上的增长量是不变的
