When you don't have to worry about criteria like that ordinary, mechanical energy rules supreme, and that's dictating where equilibrium lies.

如果你不担心像这样的要求，通常的机械能就占据主要地位，并且决定平衡位于何处。

In some sense, that's one reason to associate this as a kind of energy, H just like mechanical energy u or enthalpy H, it's the minimum free energy state that is the equilibrium state under the relevant conditions.

在某种意义下，这是我们把这些物理量称为能量的原因，就像机械能U和自由焓，具有最小自由能的状态在特定的条件下,就是平衡态。
