用付氏变换将点源二维地电断面的三维边值问题,变换成二维边值问题。再用格林公式和边界单元法解二维边值问题,并由付氏反变换,获得三维空间中的位。与有限单元法比较,本方法所需的计算机内存少,原始数据的输入简单,且有较高的计算精度,可在小型甚至微型机上运算。 Using Fu’s transformation, the three-dimensional boundary value problem of point-source two-dimensional geoelectric section is transformed into two-dimensional boundary value problem. The two-dimensional boundary value problem is solved by the Green’s formula and the boundary element method, and the bits in the three-dimensional space are obtained by inverse Fourier transform. Compared with the finite element method, this method requires less computer memory, the input of the original data is simple, and the calculation accuracy is high, so it can be operated on a small or even a micro computer.
