Study of the Gravitational Energy in Neutron Stars 中子星内引力能的研究
The gravitational force is in the direction potential energy. 的方向，和势能增加的方向，注意，当我在这里。
Let me first give you the formal definition of gravitational potential energy. 我先给你一个对于, 重力势能的形式定义。
When I'm here, the gravitational potential energy increases in this direction. 重力势能，朝这个方向增长，重力。
Gravitational Field in the Ideal Gas Thermal Cycling and the Potential Energy into Heat. 重力场中理想气体的位能热循环及热功转化
So you're using, then, the conversion of gravitational potential energy to kinetic energy. 所以你在利用, 重力势能, 转换成, 动能。
Experimental study on metallurgical characteristics of swirling reactor driven by gravitational potential energy 重力势能驱动旋流反应器及其冶金特性的实验研究
A SOF has application in particular to a positive energy proof and energy localization for a gravitational system. 这种特定的标架在重力系统的正能量定理证明上特别有用。
You can install a disk in your car, which I would call, then, a flywheel, And you can convert the gravitational potential energy. 可以在车内装个圆盘, 可以称之为飞轮, 可以转化, 重力势能。
Now, what we would like to do is we would like to convert all this gravitational potential energy into kinetic energy of that disk. 现在要做的，就是要转化，所有这些重力势能，变成圆盘的动能。
