【摘要】 按照弹性理论，将平均压力作为体系的流体静力学压力，进而得出熔Ｈ和自由能Ｇ的新定义。通过对功的计算证明这是合理的．从而扩大了Ｈ和Ｇ的应用范围。更多还原

【Abstract】 according to the elastic theory,the average pressure,is takenas hydrcatatic pressure of system. Therefore,the new definitions about enthalpy H and free energy G aregiven. Those are proved to be reasonable through calculation,As a result,applications of H and G areexpanded.更多还原
