P-V图中负斜率直线过程热量和温度变化

The Heat and Temperature Variations of Line Process in the P - V Graph With Negative Slope

分析了理想气体循环过程中负斜率直线过程温度、热量变化,得到负斜率直线过程与热量转换点并不重合.本文的结论可用于计算循环过程中的效率问题.

The heat and temperature variations of straight line process in P-V graph of the ideal gas with negative slope has been discussed. It is found that the line process with negative slope does not coincide with the transition point of the heat. Our results can be applied to the problem of the efficiency in the cycle process.
