计算机模拟电偶极子电场中的电势及场强分布

Simulation for Electric Potential and Electric Field Intensity of Electric Dipole Field

在医学物理课程中,电磁场内容理论性强,比较抽象,学生难以深刻理解各物理量的意义。利用有限元软件FlexPDE对电偶极子电场中的电势及场强分布进行了计算机模拟,以图形化的方式显示其分布,图形显示结果与理论推导得出的结论是一致的,而且计算机模拟能够帮助学生更加清晰、形象地认识电偶极子电场的分布形态,对学生理解和掌握电磁场中的一些抽象概念和理论有所帮助,提高学生的学习兴趣。

In medical physics,the theory of electromagnetic field is difficult to understand for students.In this paper,we simulate the electric potential and electric field intensity of electric dipole field by FlexPDE,and show their distribution by graph.These graphs are consistent with the theoretical conclusions.This simulation can help students understand the electric dipole field more vividly,and enhance their learning interest.
