摘　　要：经过多年的发展,统计物理对自发磁化进行了深入研究并取得丰硕成果。但是对该理论,很多学生难以建立相应物理图像。借助自发磁化的渗流模型和Java语言,我们将自发磁化过程中铁磁物质磁性有无与系统微观形貌上所定义集团连通与否这一定量关系动态直观地展示给学生,从而达到增加感性认识,提高教学效果的目的。In statistical physics,spontaneous magnetization has been extensively studied and is already well un-derstood. However,for many students,it is difficulty to establish the images of the theory. Based on the percola-tion theory of spontaneous magnetization,we can quantitatively visualize the relationship between the magnetic properties of ferromagnetic materials and the connection of special defined spin clusters,with the help of Java. This animation can help students establish the physical images,and then improves the teaching effectiveness.
