And so that led us to the definitions of other energy quantities, the Helmholtz and Gibbs free energy.

这就要求我们定义,其他的和能量相似的物理量，亥姆赫兹和吉布斯自由能。

And knowing now how to calculate these free energies especially the Helmholtz and the Gibbs free energies,that's what's going to guide us in really calculating quantitatively, OK, where will equilibrium lie.

知道如何计算,这些自由能,尤其是亥姆赫兹和吉布斯自由能之后,这些数值计算就能告诉我们，平衡态到底是什么样子。

We discovered that the quantity dA, under conditions of constant volume and temperature, dA TS And A is u minus TS.

我们发现在恒定的体积和温度下，亥姆赫兹自由能的变化，小于零，is，less，than，zero。,亥姆赫兹自由能A等于内能u减去。
