A sets of transforms are introduced in this dissertation, by using of which some kinds of topographies, such as continental slope and ridge, can be converted into flat bottom. the processing simplifies the generation of internal tides and reflection of internal waves over those kinds of topographies
針對海洋中的一些地形，如陸架陸坡地形、海山地形、海溝地形，提出了一組坐標變換，該變換可以將這些海底地形變換成平底，從而使得在這些特徵地形上內波的傳播和內潮的產生問題得到很大的簡化。The thesis shows its originality in the following aspects : first, it attempts to take a positive mean to explore the cultivation functions of chinese mass media and gives a systematic test of the relation between the perceived reality, media reality and the objective reality ; investigates media effects on the audience and their outlooks, and comes to the conclusion that the length of watching tv is not the leading factor affecting the cultivation effects and it doubts the applicability of the cultivation assumption in china. second, it scans all the tv series shown in different provinces in china, does a sample analysis and outlines the violence on screen in china
本論文在如下方面具有創新意義：首次嘗試以實證方式探討我國大眾傳媒的涵化（培養）功能，比較系統地檢驗了觀念現實、媒介現實及客觀現實三者之間的關系，考察了媒介現實對受眾觀念的作用，發現收視時長並非影響涵化效果的決定性因素，從而對涵化基本假設在中國的適用性提出質疑；首次對全國省級以上衛視臺黃金時段播出的電視劇進行全面掃描和抽樣分析，勾勒出中國大陸熒屏暴力的基本素描。It is found that : ( 1 ) for linear slope, redistribution of incoming energy flux in modenumber space depends on both the modenumber of incident waves and the ratio of the slope of incident wave ray to slope of topography ; both the transmitted and reflected energy flux ( only for supercritical linear slope ) focus near one or two modenumbers ; for supercritical linear slope, the energy flux scattering to higher modenumbers becomes larger and the energy flux to lower modenumbers becomes smaller as the slope of incident wave ray comes near to slope of topography ; ( 2 ) for convex slope, energy flux is redistributed in wide - range modenumbers and also show peaks on lower - modenubers and higher - modenumbers ; ( 3 ) for concave slope, energy flux is also redistributed in wide - range modenumbers, but does not show peaks on higher - modenumbers as supercritical linear slope and convex slope do ; ( 4 ) the total energy flux scattering to higher modenumbers is approximately equal to the total energy flux to lower modenumbers for internal waves propagating over both convex slope and concave slope, which means the concave slope is the same efficient to convex slope in scattering energy flux to higher modenumbers ; ( 5 ) for convex slope, the wave ray reflected from near - critical topography can extend to deep ocean and shallow shelf, while for concave slope, the wave ray reflected from near - critical topography can only extend to limited distance, then meet the topography and be reflected again ; generally the shear of the internal waves reflected twice from concave slope is not enhanced while the enhanced shear does also appear before second reflection takes place, the enhanced shear can bring about intense mixing, so internal waves reflected from concave slope can also produce marked mixing near critical slope
3 、內波在凹地形上傳播時，能通量在模態上的分佈范圍也比較寬，但與凸地形和超臨界線性斜坡地形相比，能通量在高模態上的分佈沒有明顯的峰值。 4 、從總的能通量來講，內波在凸地形和凹地形上傳播時，向高模態散射的能通量與向低模態散射的能通若十地形下內波傳播及內潮生成問題的理論解量近似相等，這意味著二者在向高模態散射能通量方面具有同等效率。 5 、凸地形上臨界點附近的反射，反射波的波射線能夠延伸到深海和陸架，凹地形上臨界點附近的反射，反射波的波射線很快遇到地形發生二次反射，一般來講二次反射后回到深海的波動其速度剪切並不很強，但是在進行二次反射之前的區域，速度剪切仍然很強，因而內波在凹地形上的反射依然能夠在地形附近區域，產生強的速度剪切區，誘發混合。
