  1. In the last forty years the research for finding solitary wave solutions has been experienced a great growth and some sucessful methods including the inverse scattering theory, backland transform, hirota ' s bilinear methods and the homogeneous balance method have been presented in succession

    近四十年來非線性演化方程孤波解的解法研究蓬勃發展，相繼誕生了一些比較成功的求解方法，如反散射方法、 b （ ? ） ckland變換方法、 hirota方法以及齊次平衡方法等，這些方法多年來得到了廣泛的發展和應用。
  2. The results show that : 1 ) the effects of interface on waves scattering are stronger in the structure with the interface perpendicular to the direction of fracture normal than that in the structure with the interface parallel to the direction of fracture normal. 2 ) when the interface is perpendicular to the direction of fracture normal, the amplitude of reflected waves and converted s - waves are higher and there are the sub - p - and sub - s - wave. 3 ) when the elastic waves propagating in the multi - stripe model, wavesforms become complex due to multiple scattering on interfaces

    研究結果表明： 1 ）界面與裂縫排列方向平行時，界面對波的散射作用大於界面與裂縫排列方向垂直時的情況； 2 ）當界面與裂縫排列方向平行時，在界面上產生的反射波及轉換的橫波幅度較大，並且有次級縱波和橫波產生； 3 ）彈性波在多條紋結構中傳播時，在界面上產生多次散射使得波形十分復雜。
  3. The first chapter states out three crucial opinions of mst theory : action - ontology, mechanism of control, and concept and classification of mst. the second chapter talks about the evolutionary opinions of turchin by introducing general evolution theories of k. popper and d. t. cambell. it also explains five stages of life ' s evolution which turchin used mst to describe : stage of simple reflex, stage of complex reflex, stage of high animal, stage of human being, and stage of social integration

    緊接著從四個主體部分來闡釋這一理論：第一部分詳細敘述了元系統躍遷理論的三個核心要點，分別是，把世界的終極實在看作是「行動」的行動本體論、多層次的控制機制論以及元系統躍遷的概念與分類；第二部分通過介紹波普爾和坎貝爾的廣義進化論思想來闡明圖琴關于進化的基本觀點，而重點在於解釋他用元系統躍遷描述的生命進化的五個階段：簡單反射階段、復雜反射階段、高級動物階段、人的階段以及社會的整合階段；第三部分通過把復雜性看作是系統的一種不可還原的性質，從而把復雜性與系統層次突現聯系起來。
  4. 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。
  5. In this pattern a new kind of infinite boundary element is developed to reduce wave reflection on the boundary. by this method, a simple and convenient numerical way is worked out and dissipation of the pore press, damping can be taken into account. it can not only solve the problem of material nonlinearity, but also be suitable for the problem of large deformation

    考慮到反射波在計算區域內經多次反射、透射和散射對計算結果可能產生較大的影響，在上述飽和砂土有限元模型的基礎上，建立了一種新的動力無限元計算模型，該模型能滿足工程計算的要求。
