摘要
本文介绍一种气体分子麦克斯韦速率分布教学的新方法,该方法可以使分布规律得以直观形象地展示,且能从多个角度动态地分析气体分子运动速率分布的特点.该方法主要利用Matlab软件中的图形用户界面(GUI),根据不同的问题研究角度自主设定参数,编辑相关的程序,描绘出速率分布曲线,并计算相关的特征速率,从图像和数值上进行比较分析.不同于用一般的作图软件所绘出的静态图像,借助GUI的模拟与交互,能够在课堂上基于不同的条件及研究角度动态地作出图像,实现课堂教学的高度交互性,有助于学生深刻理解麦克斯韦速率分布,提高课堂教学的效果.此外,该方法在其他分布函数的教学中也有广泛的意义.
A new method of teaching Maxwell speed distribution of gas molecules is investiga- ted in this paper. The method can make the distribution regularity visually displayed, and dy- namically analyze speed distribution characteristics of gas molecule motion from multiple view points. This method is mainly based on the application characteristics of Matlab software. U- sing the graphical user interface in Matlab software （GUI）, we can independently set parame- ters based on different problems of research angles, edit the associated program, depict the speed distribution curve, calculate the relate characteristic speed, and do comparison and anal- ysis from the image and the numerical value. Unlike with general drawing software for static image, using the simulation and interactivity of GUI, we can make dynamic image based on different conditions and research angles in the classroom to realize highly interactivity in teach- ing, which can help students to deeply understand the Maxwell speed distribution and improve the efficiency of teaching. In addition, this method also has broad implications in other distri- bution {unction teaching.
