grain boundary scattering 晶界散射
Since the problem is nonlinear and ill-posed,then it is turned into a minimizing problem by using the Tikhonov Regularization method;and the quasi-Newton method is used to solve the problem and give an approximation to the scattering boundary.
由于反散射问题既是非线性的，又是不适定的，本文利用Tikhonov正则化方法将反散射问题转化为一个极小化问题，然后用拟牛顿法求解这个极小化问题，从而得到了散射区域的一个逼近。
