用温熵图讨论理想气体直线过程

STUDY ON IDEAL GAS STRAIGHT LINE PROCESS WITH TEMPERATURE ENTROPY GRAPH

采用Ｔ—Ｓ坐标来处理理想气体直线过程，得出的结论远比使用Ｐ—Ｖ 坐标来处理更为直观、方便：从Ｔ—Ｓ图上还能直接找到温度最高点及吸放热转折点。

The T-S graph dealt with ideal gas straight line process has been adopted in this paper. Results show that the method are more audio-visual and convenient than P-V graph.The move over the top of temperature and the turning point of absorption/development of heat are directly found out from the T-S graph.
