  1. On the basis of research available and through seven aspects : the family structure, vocational structure, the structure of the mode of life, psychological and cultural structure, income structure, organization structure and social identity, the thesis reflects the process of urbanization in the community between rural and urban areas, especially demonstrates the unique characteristics of urbanization in the community between rural and urban areas of the east of china by taking shui village and kong village in anning district lanzhou city of gansu province as the example and using the advantage of multiple subjects such as sociology, anthropology, economics, etc. the transition of the community between rural and urban areas is their imitation and incorporation into the urbanization, and the effect of their spread and radioaction

    本研究在已有研究的基礎上，應用社會學、人類學、經濟學等學科的綜合研究的優勢，以蘭州安寧區水村和孔村為例，通過對兩村家庭結構、職業結構、生活方式結構、心理文化結構、收入結構、組織結構和身份認同等七個方面的實證研究，反映了城鄉結合部的城市化進程，特別是反映了中國西部內地城市化進程獨特的特點。城鄉結合部轉型過程是城鄉結合部自身模仿、融入城市以及城市的擴散輻射效應嵌入的過程；城鄉結合部是許多矛盾、困惑及經驗反映最集中的場所；同時是將漫長的城市化進程濃縮在一個短期內進行的相對較小的區域。
  2. But to circular plate with large surface area, the vibrate modes generated is often so high that there is reverse phases existing, which result in a decrease in radiation impedance, electric - acoustic efficiency and the electric power, as well as poor directivity

    然而對于輻射面積較大的彎曲振動圓盤，一般激勵的振動階數比較高，因此存在彎曲振動的反相區，導致換能器的輻射阻抗下降，電聲效率和聲功率降低以及指向性變差等問題。
  3. The processing results of velocity tomographic section and image section of reflection in depth domain has provided encouraging geological results in the areas of shengli caoqiao, yong an, luo jia, wen liu of zhongyuan oilfield and ba mian he of jiang han oilfield

    速度層析剖面與反射波深度域成像剖面等處理成果在勝利油田草橋、永安鎮、羅家，中原油田的文留地區，江漢油田的山東八面河地區均取得了良好的地質效果。
  4. Study method of sediment color reflectance in shelf has been established based on lots of investigative studies, obtained more than 7000 units of data of color reflectance using minolta cm - 2002 spectrophotometer from 165 cores in the yellow sea and the east china sea, illustrated the distributional rules of color reflectance in sediment of the shelf of south yellow sea, the shelf of north east china sea shelf and okinawa trough for the first time

    本論文基於大量的實驗研究，建立了陸架沉積物顏色反射率的研究方法。利用minoltacm - 2002光譜光度計測量了黃海、東海海區的165個巖心樣品，獲得了7000多個有效的顏色反射率數據，首次給出南黃海陸架、東海陸架北部、沖繩海槽等海區沉積物的顏色反射率分佈規律。
  5. 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。
