摘要
受棘轮机制的启发,利用势阱作为无形的棘齿构建了一个能导致电子定向运动的系统模型,并从微观角度作了详细分析,分析结果表明电子的逸出是一个偏离平衡的自发过程,此过程能在产生负熵的同时不消耗有序能.对模型的动力学特征作进一步分析表明,系统具有一般自组织系统普遍的自组织行为特征,并支持"孤立体系可存在零代价的突变"的论点.从不同角度重新分析麦克斯韦妖问题并对热力学第二定律的普适性表示质疑.
With the inspiration from ratch mechanism,used potential wells as invisible ratchets to form a system model that can induce directional movement of electrons,and methodically analyzed it from a micro-perspective.The result of the analysis showed that thermal electron emission is a spontaneous process that can cause the system to deviate from equilibrium and produce negative entropy without consuming available energy.The result of further analysis on the model＇s dynamic characteristics showed that the system and common self-organizing systems share universal characteristics of self-organizing behaviors.The result also supports the argument：catastrophic changes with zero cost can exist in isolated systems.Reanalyzed the Maxwell ghost issue from different perspectives and questioned the universality of the second law of thermodynamics.
