摘要：

本文基于Kirby的抛物型方程法理论,建立了波浪传播变形数学模型PEM,该模型在反射和非线性影响较小的情况下,可以快速准确地计算波浪折射、浅水变形及小角度的绕射,很适于计算自外海至近岸大范围水域的波浪传播变形。

Based on J. T. Kirby's theory on parabolic equation method, a mathematical model of wave transformation (PEM) is presented in the paper. Using this model, wave refraction, wave transformation in shallow waters and wave diffraction in minor angles may be calculated rapidly and accurately when wave reflection and non-linear effect are insignificant. Thus, the model is more suitable for calculating wave transformation in large waters from offshore to nearshore.
