The equilibrium state is the one, and it's just one, in which there are no spontaneous changes that can take place to any other state.
平衡态是一个,而且仅仅是一个态,这个态不会发生自发变化,变成其他的态。
Sometimes subtle changes in the structure of a protein can convert it from an active state into an inactive state.
有时蛋白质结构上一些很小的变化,就能将其由激活态转变为非激活态
But now, what happens if, instead we look at what happens when we go to some state one to some other state two and it's the pressure. Or the volume, that changes.
但是现在,我们看看如果,我们关系从状态一变化到状态二时,体积或者压强发生变化。
Delta u, delta H, familiar state functions, q w changes in their values, q, w, heat and work.
U,△H,很熟悉的态函数,它们的值在变化;
You know how pressure changes with temperature at constant volume if you know the equation of state.
如果你知道状态方程,知道在体积恒定的时压强如何随着温度变化。
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。
