摘要
本文对文[1]中提出的二维长波方程给出了数值求解方法。由于此方法无需处理边界上的积分,不仅使数值计算的数据准备工作量大大减少,缩短了计算时间,降低了计算误差,而且没出现文[2]提到的短波长噪音干扰。用本文建立的方法,计算了我国渤海的M_2分潮,计算结果与实测结果吻合较好。
.This paper presents a numerical method for solving the two-dimensional long-wave equations given by [1],Since the method needn't treat the integral on the boundary, not only the amount of data preparations on the numerical computation is reduced, the computing, time is shortened, the computing error is lowered, but also the interference of the short-wave noise cited in [2] does not appear.The M2 component tide in the Bohai Sea is calculated by the method give in this paper. It is more satisfacting that the calculated result coincided with the observed data.
