But calculating it alone doesn't necessarily tell us whether or not it will just happened of its own accord.
但是计算这些物理量并不一定能够告诉我们,这些变化是否会自发的进行,而这正是我们想要做到的。
-
it's a two-and-a-half-year-long program that mixes biology, chemistry, physics and computer science together.
这门课是一个两年半的项目，涵盖了生物学、化学、物理学，还有计算机科学。
-
OK, now what we'd like to do is be able to calculate any of these quantities in terms of temperature, pressure, volume properties.
现在我们想要做的是能够利用,温度，压强和体积的性质,计算上面的物理量。
-
And that's what led us to a number of results to determine what quantities we even need to be looking at.
这就要求我们考察一系列结果,然后决定到底需要计算什么物理量,来找出。
-
That is, in terms of equations of state. For any material Then we would really be able to essentially calculate anything. Anything thermodynamic.
换句话说，利用任何一种物质的状态方程,我们就能够实质上,计算所有物理量，所有热力学量。
-
You can still calculate the heat that's released. This is what will tell you under some particular conditions what will actually happen. Where will you end up.
你仍然可以计算放热,在特定条件这些下这些物理量,能告诉我们将会发生的事情。
-
Certainly in principle we know how to calculate this and other stuff for a change in state of this sort, for lots of changes of state.
的确原则上我们可以对某个状态变化,计算这些物理量,或者其他物理量，对其他的变化也可以做相同的计算。
-
So we have this condition that's established in a quantity that we know how to calculate.
在种种条件下,我们得到了一个我们知道如何计算的物理量。
-
Here is what we calculate to tell whether it happens spontaneously.
这就是我们所需要计算的物理量,它能够告诉我们变化是否会自发发生。
-
So we know how to calculate it. Make sense?
我们知道如何计算这个物理量，对吗？
-
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。
