摘　　要：运用分步拟谱法,以Chebyshev多项式为基底,对偏微分项进行谱展开,建立了拟谱法数值求解二维潮波方程的计算模型,模拟计算了均匀方池水柱微扰引起的水波运动,并以大亚湾海域为背景,由静止水位算起,模拟计算了区域的潮流。By using the splitting-step pseudospectral method, the partial-differential terms of equations are expended based on Chebyshev polynomials. Then the theoretic model of pseudospectral method to solute the two dimensional tide-wave equations is obtained. Based on these, the water wave caused by a tiny water column in an even square pond, and the tide wave of the domain in Daya Bay is calculated.
