  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. The influence of y _ 2o _ 2s : eu phosphors fluorescent spectra, chroma and luminescence intensity is systematically studied when different concentration of europium is adulterated into different phosphors by means of xrd, fluorescent spectra analysis, time - basing spectra analysis, long - persistent fluorescent spectra analysis and so on ; the influence on y2c > 2s : eu phosphors structure, luminescence intensity and long - persistent curve is investigated when different concentration of mg24 " > ti4 " 1 " is adulterated into different phosphors, finding the most suited concentration of mg2 " * ti4 " 1 " ; base on the suited concentration of mg2 + > ti4 +, the influence rule on phosphors luminescence intensity and long - persistent curve with changing of eu + concentration is also studies. at the same time, by using rare - earths metals adulteration and theory of chroma synthesis, the possibility of sensitized buildup of phosphors and the synthesis of different color long - persistent phosphors is also researched

    應用x射線粉末衍射( xrd ) 、熒光光譜、時間分辨光譜及磷光體長余輝壽命測試等綜合實驗手段,較系統地研究了摻雜eu對熒光體y2o2s : eu熒光體的發光光譜、色度和發光強度的影響;研究了不同mg , ti含量對磷光體基質結構性能、發光強度與余輝曲線的影響及其適宜的摻雜濃度;基此,研究了在給定mg , ti含量時,不同eu摻量對磷光體發光強度和余輝的影響規律;從稀土摻雜和色度合成原理分別探討了eu的發光敏化增強和制備不同光色長余輝磷光體的可能性。
  3. Intensity - time curve examination

    時間曲線檢查
  4. 2. on the basis of analyzing experimental data for slope land of loess plateau in different slope gradient and rain intensity and soil and water conservation tillage measures, using curve - fitting techniques, a soil infiltration rates model was woke out, the accuracy of the model is tested by a series of experiment data, the result of these indicate that the soil infiltration rates model is accurate and has good stability for slope land of loess plateau. 3. using soil infiltration rates and runoff time and wetting frontal surface depth of soil infiltration reflect effect of factor affecting soil infiltration rates

    ( 3 )採用土壤穩定入滲速率、坡面開始產流時間、土壤濕潤鋒面下滲深度三個指標來反映坡耕地土壤入滲影響(土壤性質、土壤初始含水率、地面坡度、降雨強度、積水深度、水土保持耕作措施等)因素效用大小,建立了各因素與三個指標的關系模型,詳細分析了不同水土保持耕作措施強化土壤入滲的影響,其中等高耕作作用最為顯著,其次是人工掏挖和人工鋤耕。
  5. The corresponding variation of olltput voltage due to the change of total laser intensity is measured by a photo detector. a displacement - time curve can be obtained by calibrating the re1ationship between block position and output voltage of the photo detector. through the use of simple mathematical operation, the bird - shell velocity and acceleration histories can be determined, and therefore the bird - shell instantaneous velocity at any points within the measurement range can be obtained

    該系統發射的一片狀激光受運動鳥彈的依次阻擋后,相應的光強度變化將被測出並轉換為位移時間曲線,經過簡單的數學運算,該系統能用來確定鳥彈速度和加速度的時間歷程,因而可確定鳥彈在被測區域內任一點的瞬時速度。
