摘　　要：麦克斯韦速率分布律是气体分子热运动在平衡态下的统计规律。其数学表达式抽象复杂,教学中不便精确计算和绘制速率分布曲线。利用Matlab GUI可对麦克斯韦速率分布律进行数字化处理,即同一气体在不同温度下的速率分布曲线、同一温度下不同气体的速率分布曲线和三种统计速率(最概然速率、平均速率、方均根速率)的计算。该工作对麦克斯韦速率分布律的教学有较大帮助。The Maxwell＇ s speed distribution law is statistical regularity of gasmolecular thermal motion on equilibrium state. As the equation form is rather complicated, it＇ s inconvenient to make accounting or draw a speed distribution curve in teaching. By using Matlab GUI, the speed distribution curves of different gases are draw at the same temperature, ones of the same gas are also draw under the different temperatures, the three kinds of statistical speeds are studied. This work can make a contribution to the Maxwell＇ s speed distribution law in teaching.
