【摘要】 从微观角度对2个相同的宏观系统间传热前、后的微观状态数进行了计算和比较,利用Boltz-mann关系证明了总熵增加,并通过对系统间传热前、后微观状态数的数量级估计,证明了过程的不可逆性.更多还原

【Abstract】 The number of microcosmic states of two same macro-systems,one of which is that the two same macro-systems don’t transmit heat with each other,the other is the transmitting heat has taken place between them,has been calculated and compared in this paper.Using the relation of Boltzmann,the increase of total entropy is proved,meanwhile,the micro-substance irreversible process for transmitting heat is also proved by estimating the number of micro-state of the two same macro-systems by transmitting heat.更多还原
