| 摘 要： | 分别运用分离变量法和有限差分法计算和分析两半无限长圆柱形导体管内电位的解析解和数值解,并通过MAT LAB编程算出其场域中一些点的电位结果,由相对误差的比较说明数值解的有效性,以此对保角变换的解析解结果进行了验证,找到缺陷并作了修正,从而说明把数值计算与求解析解综合起来分析场域内的电位分布会使结果更加可靠和准确.

| Abstract: | Taking advantage of separation of variables and finite difference method the analytic and numerical solutions of potential distribution in infinite two-half-cylindrical conductor tube are obtained and analysed, and the results of the electric potential of some places of fields area are figured out by compiling computer program of MATLAB language. Comparing the relative errors between them, the numerical method is effective. Thereout taking advantage of the numerical, the analytic solution of conformal transformation is validated, and the flaw of the analytic solution is found and corrected. |
