| 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. |

| Keywords: | system transmitting heat the number of micro-state irreversible process |
