摘　　要：用Matlab软件对麦克斯韦速度及速率分布函数进行了编程,绘制了相应的分布曲线,讨论了不同温度和不同分子质量时麦克斯韦速率分布曲线的变化,并用Matlab的符号计算功能计算了分布在三个典型速率区间的分子数占总分子数的百分比,所有变化规律均符合热学理论中的分子运动规律,为教学提供了参考。It was simulated the Maxwell speed and velocity distribution function and drawed corresponding curves using Matlab software.It was discussed the variations of the Maxwell speed and velocity distribution curves with different temperatures and different moleculars.Molecular percentage in three typical rate was calculated by Matlab symbol calculation function.All of thses changes are consistent with the thermology in the theory of molecular motion and providing the references for thermology teaching.
