| 摘 要： | 在计算点源二维地电模型的电场问题时，波数的选取非常重要。我们在文中以半无限均匀介质为例，推导出波数满足的非线性积分方程，确定了积分区间，并给出积分区间与积分精度的关系。试算了一组r对应的波数。

| Abstract: | The selection of wave number is very important in computation of problem of electric field in the layered model with 2D electric point sources. In this essay a nonlinear integral equation of wave number is derived, and the integral limits and the relation between limits and precision of integral has been acquired with respect to a half intinite uniform model. Finally a group of wave number of r was calculated. |
