摘　　要：在含有负斜率直线的可逆循环中,热的迁移方向不能从PV图上直接看出来,为此,用TS关系对其进行讨论,画出TS图,根据熵的变化,可以直接知道热的迁移情况。In the reversible cycle with a negative slope straight line,the transferring direction of heat is not obvious from the PV diagram.This paper aims to discuss it by means of TS relationship,then to draw out the TS diagram from which the transfer of heat can be directly seen by the entropy change.

关 键 词：负斜率直线 可逆循环 理想气体 温度 熵
