摘要

考虑了实际热机的效率。根据熵产最小原理，证明了在最优功率下，这种机器的最大效率为n= 1-√T2/T1，这是由冷却器和加热器温度的根依赖关系定义的。这一令人失望的结果早在卡诺循环功率优化时就得到了。本文从更一般的条件推导出上述表达式。我们证明，它可以适用于描述生物和非生物自然界的全球变化。

Some aspects of optimizing the power of a real heat engine

The efficiency of a real heat engines is considered. Basing on the entropy production minimum principle it is shown that the maximum efficiency of such a machine with an optimum power is n= 1-√T2/T1 defined by the root dependence of cooler and heater temperatures. This disappointing result was obtained earlier for the optimizing the power of Carnot cycle. In this paper we derive aforementioned expression from more general conditions. And we show that it is could be applicable to describe global changes in living and nonliving nature.
