接下主要内容介绍了准一维流动，接著讨论扰动流与非稳态流。 - The next large block of lectures covers quasi - one - dimensional flow , followed by a discussion of disturbances and unsteady flows
接下的一大块内容介绍了准一维流动，其后是关于扰动流与非定常流的讨论。 - Prediction of hydrodynamic pressure . the thesis presents a practical engineering method to predict the hydrodynamic pressure on instantaneous wet ship surface
关于水动压力预报：本文提出了基于二维扰动流场频域稳态解的一种预报船体瞬时湿表面压力分布的工程实用方法。 - The major work is as follows : solution of two dimensional radiation or diffraction fluid field . this thesis extends multipole expansion method to adapt to disturbed fluid fields of 2d floating bodies with asymmetric forms , which is applied with symmetric forms originally . and given the solution of potential velocity and hydrodynamic pressure of radiation and diffraction fluid fields , which is incited by a 2d arbitrary form , actual application field of the multipole expansion method has been enlarged
关于二维扰动流场的求解：将通常仅适宜求解具有对称形状二维物体扰动流场的多极展开法(保角变换方法)扩展至非对称形状二维物体，给出了任意形状二维物体的辐射和绕射流场的速度势及水动压力的频域解，进一步扩大了多极展开法的实际应用范围。 - Second , we discuss the influence of environmental referance potential temperture and thermal wind on mesoscale symmetric instability . we find the expression of disturbance stream function and criterion of symmetric instability by analytical method and conclude that change caused by environmental referance potential temperture with height and thermal wind make critical richardson number and disturbance critical half - wave length of symmetric instability larger , that is to say , they benefit the occurance of symmetric instability . third , we study nonlinear perturbation analysis of mesoscale vertical circulation and evolution equation by means of f - plane . non - hydrostatic balance and filiter model
第二，讨论了环境位温与热成风因子对中尺度对称不稳定的影响。运用解析的方法求出了扰动流函数的表达式和对称不稳定的判据，发现环境参考位温随高度的变化与热成风因子使得对称不稳定临界理查逊数及扰动的临界半波长都变大，这有利于对称不稳定的发生。第三，采用f平面、非静力平衡、滤声波模式，讨论了中尺度垂直环流非线性摄动分析及演变方程。
