摘　　要：讨论了利用虚拟电导率和虚拟介电常数求解含有电位悬浮导体的电准静态场和静电场的电场分布方法 ,通过分析实例 ,找到了这两种方法的有效应用范围 ,该方法突出的优点在于对于悬浮导体的数目没有限制 ,程序编制简单 ,稍加修改即可用于三维场的计算。应用此方法对算例进行计算得到的计算结果与导电纸实测结果相吻合 ,从而验证了该方法的正确性。该方法便于工程技术人员实际操作 ,程序的可复用性较强 ,为以后解决类似工程问题提供了依据。This paper discusses the method of solving the distribution of electric field for the electric quasi static field and static field with electric potential floating electrodes. Through the analysis of instance, we find the effective application range of these two kinds of methods, which will offer basis for similar project problem. The outstanding merit of this method is that it has no restriction with the number of floating electrodes. It is easy for us to programme and farthermore revise for three dimensional calculation with a few changes. The result of the conducting paper test shows that this method is valid. It is convenient for engineers and technocians to operate actually, and the program can be applied to other occasions easily.
