  1. Considering the similitude law for shaking table test, we study the test results and obtain some conclusions which are a ) generally, the silty soil in test box liquefies and the liquefied time has relation with the amplitude of acceleration, b ) when the intensity is on and above eight degree, the silty soil deposit will be liquefied dramatically, c ) the relationship of the pore water pressure is relevant to the cycle loading which represents when the cycle loading ranges from little to great, the relationship is represent as a concave curve, or else as a protruding curve and tends to stability. ( 3 ) based on the triaxial compression test and the resonant column test, some studies are made such as a ) the duncan - chang parameters of constitutive model, b ) the dynamic shear modulus ratio and c ) the damping ratio of the site soil deposits. in order to deal with the test data, a computer program is compiled

    （ 2 ）利用小型振動臺進行了k _ 0固結狀態下粉土的振動液化模擬研究，通過分析正弦荷載作用下的試驗資料，驗證了粉土的孔隙水壓力增長模式的合理性；從微分方程推導了基於土體振動臺模型試驗的相似律，並從模型實體、孔壓時程曲線和相似律等方面做出了分析，得出了如下結論：在小型振動臺試驗中，模型箱中的粉土都發生了液化，液化的時刻和輸入加速度幅值有關，而對頻率的變化不太敏感；粉土在相當於8 9度地震烈度的加速度幅值作用下可能產生嚴重的液化；孔壓的增長曲線形狀與施加的荷載有關：當施加荷載為由小到大的形式時，曲線形狀為上凹的曲線；當施加荷載為等幅的正弦荷載或荷載幅值由大到小時，曲線形狀為上凸的曲線，且逐漸趨于穩定。
  2. According to the thermodynamics theory of vapor compression refrigeration cycle, hfc - r134a is chosen as refrigerant fluid and the thermodynamics calculation of refrigeration system is accomplished, which is based on the table of r134a thermodynamics characteristics and estimate of portable refrigerator ' s calorific burthen

    本文根據蒸汽壓縮式製冷循環的熱力學原理，從小冷量、小體積的便攜式冷藏箱的熱負荷計算出發，以所選用製冷劑（ r134a ）的熱力性質表為依據，進行了製冷系統的基本熱力計算。
  3. Research on routing table compression and storing in ternary content addressable memory

    基於三態內容尋址存儲器的路由表壓縮和存儲技術研究
  4. As well as, using vector operation substitute scale operation in order to improve compression rate condition on keeping on distortion. by tool of vc + + simulate the result of research. finally, compared with jpeg, we can draw on a condition : using dct table substitute dct calculate and using vector operation substitute scale operation which can attain that is high compression rate and steady distortion

    其中，在dct變換中通過使用dct查詢標的方式代替dct常規變化，達到減少計算機乘除運算次數的目的；量化過程中通過使用矢量量化代替標量量化，達到在保證最小失真度的前提下提高壓縮比，並因此省略了jpeg壓縮中的熵編碼過程，簡化了壓縮過程，同時獲得最佳壓縮效率。
