对“循环效率的一个注记”一文的不同意见

SOME DIFFERENT OPINIONS ABOUT THE ANNOTATION ON EFFICIENCY OF A CIRCLE

指出《大学物理》１９９７ 年第９ 期上“对循环效率的一个注记”一文中的效率公式是不准确的，在某些情况下会导致错误的结果．应从能量守恒和转化去把握效率公式中 Ｑ１ 和 Ｑ２

The formula η=1-Q 2Q 1=1-Q C 1B +Q BC 2 Q C 2A +Q AC 1 about efficiency in the annotation of circulating efficiency is not accurate,because it will bring about a wrong conclusion in some cases.The meaning of Q 1 and Q 2 in this formula should be understood in the aspects of the conservation and conversion of energy.
