| 摘 要： | 波能平衡方程是研究风浪要素及波能传播问题的很有效的方法，计算较为简单，在海洋学及海岸动力学中得到广泛的应用。本文采用考虑波能侧向传递机制和耗损制约的波能平衡方程组作为研究波浪折射——绕射变形的控制方程。对数学模型用差分法进行了数值模拟，并用两个例题进行了验证

| Abstract: | To solve problems concerning wave elements and wave propagation, it is an effective way to employ wave energy balance equation which is widely applied in oceanography and ocean dynamics for its simple computation.The present paper advances wave energy balance equations considering lateral energy transwission and energy loss as the governing equation for the study of wave refraction and diffraction. For the mathematical model, numerical simulation is made by means of the difference method and the result is verified in two examples. |
