摘　　要：物理学不宜全盘照搬工程技术学的概念.计算任意逆循环的致冷系数,仍可应用公式ε=Q_2/(Q_1—Q_2),且宜明确区分循环是否为回热式.任意可逆循环的致冷系数,不小于工作在它所经历的最高热源温度和最低热源温度之间的可逆卡诺循环的致冷系数,这并不违反卡诺定理.It is not suitable to copy indiscriminately the concepts of engineering technology inphysics.The formula ε=Q_2/(Q_2-Q_2)can be still applied to the calculation of the refrigenat-ing coefficient of the arbitrary reversed cycle and it should be definitely distinguishedwhether the cycle is regenerative.The refrigerating coefficient of the arbitrary reversible cy-cle is not less than that of the reversible Carnot cycle operating between the maximum andminimum heat source temperatures undergone by the arbitrary reversible cycle and this doesnot violate the Carnot theorem.

关 键 词：逆循环 致冷系数 回热循环 卡诺定理
