电绝缘用发泡泡末塑料的相对介电常数和损耗因数的试验方法
Firstly , as a forward problem is solved for each iteration of ga reconstruction , calculating the electric field for a given distribution permitivity and driving source - this aspect will be treated with more detail . the thesis uses finite element method ( fem ) to solve it , because fem can conveniently handle inhomogeneous dielectric , converge well , and spare computing time by compacting the matrix
本文首先建立了介电成像的数学模型，采用有限元方法求解正问题，有限元方法的优点在于能方便地处理非均匀介质、具有良好的收敛性、可以压缩系数矩阵而节省计算时间，这有利于应用遗传算法进行优化。
