氢气分子速度分布的仿真实验

Simulation experiment of hydrogen molecule velocity distribution

通过计算机仿真实验,可以绘制不同温度下氢气分子速度分布的二维曲线和三维曲面。根据麦克斯韦速度分布函数,借助于计算机仿真软件MATLAB的数据可视化功能,取温度为400 K、500 K、600 K、700 K和400 K、900 K、1 400 K,依次对氢气分子的二维和三维速度分布图进行仿真实验,结果表明:通过计算仿真能够准确地得到氢气分子速度分布规律。

With computer simulating experiments, we can draw the 2 d curve graphic and 3 d curve graphic of re-locity distribution of hydrogen in different temperature. According to Maxwell velocity distribution function, we make simulating experiments in computer about the 2 d curve graphic and 3 d curve graphic of velocity distribution of by-drogen in turns in 400,500,600,700 K and 400,900,1 400 K, by means of computer simulation software MAT- LAB. The results show that we get the accurate velocity distribution law of hydrogen by means of computer simula-ting technology.
