地球──开放的热动力学系统

The Earth:An Open System of Thermodynamics and Dynamics

动力学讨论的是一个轨道世界和封闭系统，热力学讨论的是一个过程世界和开放系统。地球的热演化历史和地球内部热状态分布确定了地球演化进程的不可逆性和各种地质作用过程的不可逆性，也由此确定了地球为一开放的热动力学系统。按各种能量的来源不同，把地球内部统一的能量系统划分为６个子系统．

The object that dynamics discusses is a world of the orbit and close system,The object thatthermodynamics discusses is a world of the process and open system,The history of thermal evolutionstate in the earth's interior has detemined that the the devolopment process of earth and the processesof all geological actions are irreversible,From these it has been determined that earth is an open sys-tem of thermodynamics and dynamics.According the to the difference of the origins among variousenergys the energy system is classed into six subsystemes。
