摘　　要：经典耗散结构对其有序的分析虽然误用了热力学第二定律和无序度的熵,但这掩盖不了耗散结构本身的价值。耗散结构的有序是耗散结构在形成过程中各因子之间形成的相互联系,它是一个宏观整体的概念,反映了系统内部的联系程度,与无序度熵有着本质的区别。对于系统内的某一粒子、要素、子系统来说是并无有序的概念可言。耗散结构中熵的实质是宏观有序和能量转换,体现的是热力学第一定律。热力学第二定律的使用前提是孤立系统,耗散结构中并不存在孤立的内部系统,无序度熵的引入,严重误导了对熵的本质理解。不能用封闭的、静态的、机械的、线性的观点看待开放的、动态的、有机的、非线性的物理过程。探讨熵的实质,对科学研究的方法和思维有重要意义。Although the classical dissipative structure theory misapplied the second law of thermodynamics and the disorder of entropy, but could not conceal the value of dissipative structure theory itself. The order of dissipative structure is the relationship of all elements during the forming,it is a macro and whole concept, reflects the relation of inner elements of the system, entirely different from the disorder entropy. For one particle, element and subsystem of the system , there is no order to say. The essential of entropy in the dissipative structure is the macroscopically order and energy transformation,and embodies the first law of thermodynamics. The precondition of using second law of thermodynamics is in an insulation system,the dissipative structure has no inner insulation system. The application of the disorder entropy seriously misleads the understanding of the essence of entropy itself. We can＇t see the opened ,dynamic ,organic and nonlinear physics process in a view of close, static, mechanical and linear. To discuss the essence of entropy is significant to the method and thinking of scientific research.
