摘要
给出了含有特征参数dQ／dA的理想气体准静态过程的微分方程，阐述了它的物理意义，进而给出判断微元过程吸热正负号的判据．
Gived the differential equation of an ideal gas in an arbitrary quasi - staticprocess with characteristic parameter dQ/dA. Furthermore, discussed it's physicalsignificance and got the criterion to determine the plus minus signs of the transferredSmall amount of heat for infinitesimal processes.
