简单系内能的特性变量与特性函数

On the Characteristic Variables and Characteristic Functions of the Internal Energy of the Simple System

以简单系的热力学函数内能U为例．证明了运用Massicu定理时独立变量的选择与附加初始条件的关系．

By taking for an example the internal energy U of the function of the thermodynamics of the simple system, the present paper has proved the relationship between the choice ofindependent variables and the appendation of initial conditions when the Massicu theorem is applied.
