摘　　要：对有限时间热力学时间问题进行了探讨 ,推导出了有限时间内不可逆卡诺热机的内不可逆熵产与最少循环时间成单调递减关系 ,并指出熵不仅能标示时间之矢 。An exploratory study is conducted of the issue of finite time thermodynamics ti m e. Deduced in this paper is a simple decreasing relationship between the minimu m cycle time and the irreversible entropy generation of a finite time endo irr ev ersible Carnot engine. It is noted that the entropy can not only mark the time arrow but also calculate the quantity of time.
