在此基础上，引进了微分熵。

On this basis, differential entropy has been led into.

从热力学第二定理出发，利用外微分构造了熵、焓以及吉布斯函数的表达式。

Expressions of entropy, enthalpy and Gibbs function are formulated by exterior differential derived from second law of thermodynamics.

首先列出了描述生长变形体能量平衡的微分方程以及熵不等式；

Firstly, the differential equations for describing the energy equilibrium of growing deformable body and the entropy inequality were discussed briefly.
