提出了一种基于数值计算的电场线微分方程求解的通用方法，讨论了求解过程中的奇异性问题，简化了微分方程的求解过程，利用Igor Pro对孤立点电荷、一对同号电荷、一对异号电荷、一对同号长直导线、一对异号长直导线、复杂电场的电场线方程进行了数值求解和可视化，比较了基于泰勒展开的网格法逐点求解与数值微分方程求解的求解精度.

A general method for solving the differential equations of electric field lines based on numerical computation is proposed. The singularity issues in the solving process are discussed, and the procedure for solving the differential equations is simplified. Using Igor Pro, numerical solutions and visualizations are performed for the electric field line equations of an isolated point charge, a pair of like charges, a pair of opposite charges, a pair of like long straight wires, a pair of opposite long straight wires, and complex electric fields. The accuracy of the point-by-point solution based on the Taylor expansion grid method is compared with that of the numerical differential equation solution.
