摘要
研究了在渗透系数相差不大的渗流场中椭圆型偏微分方程的系数反问题 ,通过把CT技术中的Radon变换推广到渗流力学中 。
The inverse problem of elliptic partial differential equation in the permeability field is discussed,whose permeability coefficient is nearly uniform.By using Radon transform in computerized tomography technology,the solution to this problem could be found,and some numerical examples are presented.
