摘要
本文提出了一个解算电磁场的新方法,这一方法基于运用数值计算寻求任意边界面上位函数与通量函数之间的关系,界面以外场的影响可以运用上述关系进行等效替换,因而称之为等效边界原理。这一方法对于复杂和大区域场的计算特别有效,因为它们的场域可以被分割为许多小的区域而容易逐一算出,基于这一原理而编制的程序对实例进行了计算,其结果非常令人满意。
a new method of solving electric and magnetic fields is presented. This method is based on the relation-ship between potential and flux for any region boundary, which may be obtained by nomerical computation.
The influence of the fields beyond the interface can be replace by the ralationshi explained above. so we call it the equivalent boundary principle. This method is very useful to complex and large-regions fields, because they can be split up into many snall regious then We Can Casing compute one by one theoty,
Based upon this we have complied a program and the consewuence of computation example is very satisfactory.
