Abstract : a numerical model for wave propagation in water of varying topography and current is proposed, and time - dependent wave mild - slope equation with a dissipation term and corresponding equivalent governing equations are presented. two different expressions of parabolic approximations for the case of the absence of current are also given and analyzed. examples of numerical simulation for wave transformation in large estuarine water areas are provided
文摘:提出了水深與流場緩變水域波浪傳播數學模型水流中依賴時間變量並考慮能耗的波浪「緩坡方程」及其等價的控制方程組，分析比較了無水流情況此理論模型與其相應的兩種拋物型近似的差別，提供了長江口波浪變形數值模擬計算工程實例.實例表明，該模型能適應河口三角洲大范圍水域波浪傳播數值計算 -
In this paper, the current states of research about the basic theory of stationary state perturbation method are firstly reviewed, on base of them, and studied some physics issues mainly about hydrogen atom. the stark effect of the energy level ( n = 4 ) of hydrogen atom is calculated and the stark effect of three dimensional hydrogen atom is discussed by the use of the parabolic coordinates, then the perturbative matrix elements for each energy level are given
本文首先綜述了關于定態微擾論基本理論的研究現狀，在此基礎上利用定態微擾論對某些物理問題，主要是對氫原子問題展開了研究，計算了氫原子n = 4能級的斯塔克效應，並利用拋物線坐標法求解了三維氫原子的斯塔克效應，給出了氫原子斯塔克效應中微擾矩陣元的普遍公式。
