摘　　要：主要研究了采用遗传算法(GA)与模拟电荷法(CSM)相结合进行电器三维电场的数值计算，在对传统CSM方法深入研究及分析的基础上，采用GA作为优化方法对模拟电荷量及其几何位置进行优化求解，达到以较少的模拟电荷进行较高精度三维电场的数值求解，并运用此原理对球-板电极、球棒-板电极结构及冲击发生器的三维电场进行实例计算，证实其可行性及实用性。The combination of the genetic algorithms (GA) and th e charge simulation method (CSM) is investigated to calculate 3D electric fields of the electric appliance. Based on the well studied and analyzed traditional C SM, the optimized charges allocations and quantities have been realized using GA as the optimization method, higher calculation precision have been achieved. Th e feasibility and practicability of the combination method are approved by calcu lating the 3D electric fields examples, such as:globe plane electrode, bar pla ne electrode and impulse generator.
