极值原理统一的一种可能形式

本文注意到最小作用量原理，费马原理，H定理和最小熵产生原理等等最小最大原理之间的差别和联系，以变分法为工具，通过考察最小熵产生原理及H定理的另一种形式，得出与最小作用量原理，费马原理相似的结论：真实运动都是以某物理虽取极值，同时还研究了各极值原理的内在机制，找出各极值原理相似的物及根源，这样不但从数学形式上而且从内部的物理机理上将他们统一起来。

A POSSIBLE UNIFIED FORM OF EXTREMUM PRINCIPLES

The differences and relations of the maximum and minimum principle are pliedto such as Least - Action principle, Fermatis principle, H Theorem, Least Entropy - producedprinciple and so on. The conclusion comes to that the real move of system state will make certainphysical quantity getting extreme value. The paper dicusses that the internal mechanism of everyextremum principles complete each other and the physical origin of similarity between them is re-vealed to a certen extent.
