摘要
将近年发展起来的多重网格方法应用于频域波动方程的数值求解，数值算例说明多重网格方法是一种最优阶算法，适宜于处理频域波动方程。最后指出了多重网格方法与微分方程数值解的小波方法的区别。
The multigrid method was applied to the numerical solution of wave equation in the frequency domain. Numerical experiments and comparisons with other classical methods showed that the multigrid method is an a gorithm of optimal order.Finally the difference between multigrid methods and wavelet methods for the solution of partial differential equations was pointed out.
