麦克斯韦速度分布律的计算机辅助教学

CAI of Maxwell-Boltzmann Distribution Law

麦克斯韦分布律是气体分子热运动在平衡态下的统计规律,具有广泛的适用性。由于其形式较复杂,教学中不便精确计算和准确绘制分布曲线(面)。用MATLAB对麦氏分布率编程,绘制了同一温度下不同气体、同种气体在不同温度下的分布曲线(面)。编程处理方便,效果形象直观,是一个实用的CAI。

Maxwell-Bohzmann distribution law is statistical regularity of gas molecular thermal motion on equilibrium state, having general applicability. As the equation form is rather complicated, a distribution curve or surface is not inconveniencely represented accurately or precisely in teaching. Through using MATLAB, the distribution curve or surface is drawed different gases at the same temperature and the same gases under the different temperature. MATLAB programme is easy used, the experiment shows the method is practical CAI and the effect is vivid.
