In this paper a numerical model for simulating propagation and transform ofwater waves in coastal area is set up by using parabolic mild-slope equation inorthogonal coordinates, and the particular format of this equation in conformal systemis also set up.

本文建立了一个基于普通贴体正交网格系统的抛物型缓坡方程模型，并给出了其在保角坐标系下的特殊形式，利用该模型研究了扩张防波堤和环形渠道内波浪的传播这两个典型算例。

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.

本文首先综述了关于定态微扰论基本理论的研究现状，在此基础上利用定态微扰论对某些物理问题，主要是对氢原子问题展开了研究，计算了氢原子n=4能级的斯塔克效应，并利用抛物线坐标法求解了三维氢原子的斯塔克效应，给出了氢原子斯塔克效应中微扰矩阵元的普遍公式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
