摘　　要：理想气体自由扩散运动的计算机辅助教学课件可演示理想气体分子实时的动态无规则运动,一方面弥补了实物实验条件限制的不足;另一方面也提高了理论课堂教学的效果。该课件直观形象地把熵和系统无序程度的联系展现了出来,更清晰地说明了两者之间的关系。The courseware development of computer-aided instruction of ideal gas free diffusion based on Labview can demonstrate real-time dynamic random motion of its molecules,which not only increases the effect of classroom teaching,but also makes up for the insufficiency of real experimental conditions.The courseware intuitively displays the contact of the entropy and the disorder of the ideaf gas,and more clearly illustrates the relationship between the entropy and the disorder.
