  1. In accordance to the defects presented in using the chinese road asphalt technical standards to assess the asphalt performance as well as the facts that the shrp test equipment of usa can not be widely employed in china since its being very expensive, the shrp rheological concept is utilized in the research project to carry out the exploration of the rheological properties of modified and non - modified asphalt by using conventional tests such as penetration and ductility. the conclusions obtained by using the conventional test rheological index to assess asphalt performance are compared with those by using the shrp rheological index and their certain correlation are found

    針對目前我國道路石油瀝青技術標準評價瀝青路用性能存在的種種缺陷,以及美國shrp試驗設備因其昂貴性而暫時無法在國內大量推廣應用這一事實,本課題試圖利用shrp流變思想,採用針入度、延度等常規試驗設備進行改性及非改性瀝青流變特性的研究,並將常規試驗流變指標評價瀝青路用性能的結論與shrp流變指標評價結論作比較,找出它們之間的相關關系,從而肯定了採用常規試驗設備進行瀝青流變特性及路用性能研究的有效性。
  2. The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment. ( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma, compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index. the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation

    結果顯示: ( 1 )人精子mr能夠誘發去透明帶金黃地鼠卵母細胞中皮質顆粒的胞吐,並引起卵母細胞膜表面微絨毛形態和數量發生改變; ( 2 )皮質顆粒胞吐后,其內容物可結合到卵膜表面; ( 3 )抗mr抗血清預處理精子可抑制精子與卵子的結合與融合,使受精率、穿透指數和結合指數下降,並均有劑量依賴性。以上結果提示,人精子mr在受精過程中起重要作用,其主要作用可能是介導精-卵膜融合併促進卵母細胞的活化。

  4. The general attenuation law of ground vibration caused by heavy tamping is verified by spectrum analysis in this paper. moreover, the relationship between attenuation index and standard penetration number is created through combination analysis of vibration attenuation and surface wave propagation

    在此基礎上,通過面波分析,得出了場地介質衰減指數和表徵場地介質性質的參數?標準貫入擊數之間的關系,給出了表達式的一般形式。
  5. Correlative function method and variable function method are used to calculate the relevant range of soil layer. the limit capacity of bored pile is determined by the cone penetration tests ( cpt ) and the static loading tests and related statistics parameters are also evaluated. considering the effects of group piles, the action effect is calculated by the settlement of pile foundation and the reliability index of single pile as well as group piles is determined by monte - carlo method

    本文選擇臨近場地的四座高層建築地基的全部勘測資料,以沿深度方向的一維平穩高斯隨機場作為樁基土層土性參數的數學模型,利用相關函數法和變異函數法計算土層的相關范圍,由cpt和靜載試驗結果綜合確定鉆孔灌注樁的極限承載力,進而對相同場地各試樁的承載力進行折算后檢驗其概率分佈,並估計有關統計參數:考慮群樁效應確定樁基承載力,由樁基沉降反算其作用效應,由monte - carlo方法計算單樁及群樁的可靠指標。
