系统已经处于自由焓最低的状态。
这就是由定义焓得到的。
相发生变化时，焓也发生变化。
A change in enthalpy also takes place when a change of phase occurs.
在高焓值区，压力越高，传热越强。
In the high enthalpy region, heat transfer is intensified by rising pressure.
焓是系统中能够做机械工的能量的多少。
Enthalpy is the amount of energy in a system capable of doing mechanical work.
通常所说的能量，或者自由焓和熵之间存在一个平衡。
There's a balance here between ordinary energy or enthalpy and entropy.
自由能，熵，以及焓。
本文将给出水溶液中离子的绝对标准生成焓。
In this paper, the ionic absolute standard heat of formation is gotten.
这个方程把吉布斯自由能中的温度变化，和焓的变化联系起来。
And it relates the temperature change in the Gibbs free energy with the enthalpy change.
但是如果系统处于平衡态，所有其他的态都不可能具有更低的自由焓。
But if the system is in equilibrium, none of those states has lower enthalpy.
我们同样可以看到如果保持自由焓,和压强不变熵的变化dS也是大于零的。
H We also saw that dS for constant H and p was greater than zero.
