With constant limited force and energy, and let in the electromagnetic wave of than light material volume, quality of material more small, the speed is faster than the speed.

以恒定有限的力与能量，任凭于比光的电磁波物质体积、质量更小的物质，则其速度就是超光速的。

We could just collect a bunch of data. For a material .What's the volume it occupies at some pressure and temperature?

对一种物质我们可以得到一系列测量数据,在给定的温度和气压下,它的体积是什么？

But because in many cases we can reasonably either model or measure equations of state, collect data for a material for its temperature, pressure, volume relations, then in fact if we can relate all these quantities to those then in fact we really can calculate essentially all of the thermodynamics. For the material.

但是因为在很多情况下,我们能够合理的给出状态方程的模型,或者通过收集一个物质的，温度，压强和体积之间的关系,来测量其状态方程，所以实际上我们可以给出压强等物理量,和热力学势之间的关系,并计算出所有的热力学势，对于给定的物质。
