From considering the interaction between wave and current , we can get a reasonable result by solving the governing equations with properly boundary conditions
考虑群柱间波?的交互作用，藉由求解在适当边界条件下的控制方程式可推导出? ?解析结果。
The interaction of wave with multiple porous circular cylinders is analyzed also . the approximate value of the hydrodynamic force act on each porous cylinder can be calculated
在此基础上进而分析了波浪对可渗透圆柱群的相互作用，推导出了作用于直线排列的群柱中单一柱体上的波浪力的近似解。
The main purpose of this paper is to treat a gravity wave field with an array of two or more cylinders and to demonstrate the wave height distribution with different flow speed or different flow incident angle in a wave - current flow field with constant depth
摘要本文的主要目的，在研究重?水波通过有限水深之群柱间时周围?场的波高现象，以及探讨波?共存时在?同?速及?同入射角?经圆柱群时所造成之波高变化。
