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。 -
Based on the hypothesis that the input for earthquakes is white noise and using the principle of random optimal control, the features of vibration control and the effects of parameters such as isolation degree, damping and ground site on them were analyzed
假定地震動輸入為白噪聲，運用隨機最優控制原理，分析了組合隔震結構振動的控制性能以及隔震度、阻尼和場地等參數的影響。 -
In phase 1, the dynamical properties in the time and frequent domains of the simple, two - degree - of - freedom models of passive, " sky - hook " and " ground - hook " damping suspension systems are examined by laplace transform
從理論上分析了被動阻尼、 「天棚」阻尼、 「地棚」阻尼懸架系統的時域和頻域動力學特性。 -
In phase 2, the nonlinear dynamical properties of the simple, two - degree - of - freedom model of mr damping suspension systems are explored by the method of equivalent linearization
運用等效線性化方法，分析了懸架系統由磁流變阻尼器而引起的非線性動力學特性。 -
Our next goal is to separate two suitable domains for the parameters m and p, where the exponent m and p determine the degree of nonlinearity of the damping term and the source term. when m p, the damping term dominates over the source term and the global solution exists for any initial data. in the proof, we use the " modified energy " and the continuation principle
然後分成兩種情形： m和p分別決定阻尼項和源項的非線性度，當m p時，阻尼項控制源項，應用修正的能量和連續性原理證得整體存在性；當p m時，源項佔主導，應用能量補償的方法得到解在有限時間內爆破。
