摘要
在热力学中,理想气体所组成的宏观热力学系统,由于不考虑重力场作用是遵从阿伏伽德罗实验定律。对于实验中的真实气体是受重力场作用的,其宏观热力学系统就不严格遵从阿伏伽德罗实验定律;如果把整个热力学系统按重力场方向分割成一系列的微观型的热力学系统,对这样的微观型系统却是遵从阿伏伽德罗实验定律。文章运用气体分子动理论和玻耳兹曼速度分布律,对重力场中的微观型热力学系统所遵从的阿伏伽德罗实验定律进行了统计证明。
In Thermodynamics, the macro-thermodynamical system which is formed by ideal gas obeys the Avogadro law without considering the function of gravity field. However , in the experiment, the real gas will be influenced by the gravity field , so the macro-thermodynamical system does not follow the Avogadro law. But if splitting the whole thermodynamical system into a series of micro-thermodynamical system in accordance with the direction of the gravity field , the micro-thermodynamical system follows the Avogadro law. In this paper, the theory of molecular dynamics and boltzmann velocity distribution law are applied to statistically prove the Avogadro law followed by thermodynamic system in gravity field.
