On this basis, differentialentropy has been led into.
在此基础上，引进了微分熵。

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

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