【摘要】 本文讨论了包含准静态直线过程在内的一般循环效率的计算方法，分析了常出现错误的原因所在指出直线过程中由吸热变为放热时转折点的温度与该过程中最高温度点并非一回事：一般的循环效率应与工作物质种类有关．更多还原

【Abstract】 The calculation of efficiency of general cycles which include quasi-static straight lineprocedure is discussed．The reasons which cause mistakes are also analysed． It is pointed out that theturning point from heat absorption to heat release and the point of highest temperature is not the samething. The efficiency of general cycle is related to the kind of working material更多还原
