摘　　要：选取广义CORS方法求解非Hermite线性方程组,确定预处理条件子,利用所获取预处理条件子运行预处理CORS算法实现广义CORS方法的预处理;利用完成预处理的广义CORS方法求解非Hermite线性方程组,使非Hermite线性方程组具有较高的收敛速度,从而实现非Hermite线性方程组的迭代终止。算例分析结果表明,采用该方法求解非Hermite线性方程组具有较高的收敛速度,迭代次数明显降低,具有较好的收敛行为及稳定性。The generalized CORS method was selected to solve the non-Hermite linear equations,and the preconditioner was determined.The preprocessing CORS algorithm was used to realize the preprocessing of the generalized CORS method.The generalized CORS method was used to solve the non-Hermite linear equations,so that the non-Hermite linear equations have a high convergence speed,so as to realize the iterative termination of the non-Hermite linear equations.The analysis results of the example show that the method for solving the non-Hermite linear equations has high convergence rate,significantly reduces the number of iterations,and has good convergence behavior and stability.
