摘　　要：多导体电容问题由于计算参数众多,公式枯燥往往令学生感到疑惑。从孤立导体电容、双导体系统电容出发,归纳出多导体系统部分电容的概念,强调电容的意义在于将空间中带电导体的场分析问题转换为电容网络的路分析问题,以Matlab编程计算和COMSOL静电场仿真证明了这两种分析方法的一致性。The problem of multi-conductor capacitance is often confusing for students due to the multitude of calculation parameters and the tedious formulas involved.The concept of partial capacitance in multi-conductor systems is derived,starting from the capacitance of isolated conductors and capacitance of dual-conductor systems.The significance of capacitance lies in the transformation of field analysis problems of charged conductors in space into network analysis problems of capacitance networks.The consistency of these two analysis methods is demonstrated through Matlab programming calculations and static electric field simulations using COMSOL.
