摘要
研究自组织现象,指明开放系统出现自组织现象符合最小作用量原理。对开放系统引入雷诺数,用雷诺数衡量开放系统远离平衡态的程度。当系统的雷诺数达到一临界值Re1时,开放系统出现自组织现象,再达到更大的临界值Re2时,自组织现象破坏,出现混沌现象。Re2与Re1的比值L越大,说明开放系统的自组织现象越稳定。研究了输运过程及沙粒移动中发生的自组织现象。
The phenomena of self organization is researced, the open system to appear the phenomena of self organization chime in with the principle of least action be indicated. To the open systems the Reynolds number be introducted. The degree that far away from the equilibrium state of the open system is measured by the Reynolds number. When system's Reynolds number achieves marginal value Re1, the open system appears the phenomena of self organization, when again achieves greater marginal value Re2, the phenomena of self organization is destroid and the chaos phenomenon are presented. The ratio L of Re2 and Re1 are bigger, The phenomena of self organization of the open system is stabler. The phenomena of self organization is researced that occurs in the transport process and the sand migration.
