This Paper analyzes and calculates fatigue of the total and the single-throw crankshaft through finite element about the diesel engine medium-height speed.
本文主要是利用有限元法对某型中高速柴油机的整体曲轴和单拐曲轴分别进行强度计算分析。
At the speed and height at which he was moving, he was never more than half a second from disaster.
以这样的速度在这么高的地方移动,他离灾难永远只有半步之遥。
Or how to define and remember the maximum height, temperature, speed?
或者是怎样界定和记录极限的高度,温度和速度?
The X-15 set height and speed records greater than those expected.

So,the point is,every object falling under gravity is given by the same formula, but there are many, many objects that can have many histories, all falling under gravity, and what's different from one object and the other object is, when was it dropped, from what height, and with what initial speed.
关键是,每一个受重力作用下落的物体,都有同样的表达式,但是各个受重力作用下落的物体,都有不同的初始条件,所以它们的区别在于,下落时刻,下落高度和初始速度
