摘要
本文应用热功内势能增量比j=dQ/(dA+dE_ρ)的概念和范氏气体准静态过程微分方程,导出了热容量在准静态过程中的一般计算公式以及给出了在P—v图上准静态过程中dQ,dT与Ci正负的比较斜率判别法则.
By the use of both the concept of the ratio--j=dQ/(dA+dEp),Which is called heat power internal energy change ratio--between heat and the combination of power and internal potential energy change.and the differential equation of quasistatic process of van der waals'gas ,the general formula is derived to compute heat capacities in arbitrary quasistatic processes ,and the rule is given for comparing the slope of arbitrary quasistatic process curve on p-v graph to determin the sign (positive or negative)of dQ、dT and Ci.
