  1. The prepared sdse modified zirconum meinbrane was tested at the wider range of tcmperaure and pressure and differellt composihons of hydrogen mixturc gases ( i. e. different hydrgen panal pressure ) in order to examine the performance of this membrane and the sole hpermselechvity of the membrane. the results showed tha the purity of the permeated hydrgen is l00 % at the base of the detection greatest lower lanit of the qhle mass spectrometer, and there was no impurity gas passed, the permeating flux and permeability of this membrane are from several decades times to one decade times more higher than tha of a palladum membran in the range of from 593k to 773k, puv = 0. 2 ~ 0. 3mpa, pdn = 4x l04pa - - 0. lmpa, the hydrogen permeatng flux is increased with the difference of the squto root of pressure, and presents a linear relationship, the pressure seems has no influence on the permeablity, the permeabi1ity is decreased with the increasing of the temperature, and presents an exponential relationship, accondng to the fitting curve of the relationship betwen the permeability and the temperatur derived from the experimenta daa, in the range of 593k ~ 773k, pup0. 2 ~ 0. 3mpa, pha = 4 x l0 # pa ~ 0

    在更寬的溫度范圍、壓差范圍內，在不同原料氣組成（即不同的氫氣分壓）條件下，對所制備的鋯表面改性膜進行了滲氫性能實驗，考核了膜對氫的唯一選擇滲透性，結果表明：在四極質譜的檢測下限內，只有氫氣存在，而無雜質氣體通過；在593k 773k溫度范圍內，鋯表面改性選擇滲氫膜具有高於鈀膜數十倍至十幾倍的滲氫流量和滲氫系數；其滲氫流量隨著膜兩側氫分壓平方根摘要差的增大而增大，並且呈線性關系；壓力對膜的滲氫系數幾乎無影響；膜的滲氫系數隨著溫度的升高而下降，井巨呈指數關系：根據對實驗數據所作滲氫系數與溫度關系曲線的擬合，在溫度593k 773k范圍內，壓差p 、 0二0
  2. Through comparing and analyzing of bearing capacity, development of crack and strain of reinforced, the results show that the load - deflection plots f or specimens from the finite element analysis agree well with the experimental data, and choosing the rightful stress - strain relationship, utilizing ansys program, the test process can be well simulated. at the same time, making used of the program, the traditional shear wall is analyzed. it shows that comparing with the traditional shear wall, the hollow shear wall ' s cracking load drop 16 %, yield load and failure load drop 13 %, stiffness drop 13 % ~ 22 %

    其次在試驗的基礎上，將試驗手段、有限元數值模擬方法和理論分析結合起來，利用有限元程序ansys對其中的兩片墻板進行非線性有限元分析，並對前後的承載性能，裂縫發展、鋼筋應變進行了比較和分析，結果表明有限元節點模型分析的荷載-位移曲線和試驗測得數據符合良好，選用合理的材料本構模型，利用ansys可以較好的模擬試驗過程；同時利用有限元模型對比分析了普通剪力墻和空心剪力墻，空心剪力墻與普通剪力墻對比，其開裂荷載下降16 ，屈服荷載、極限荷載下降13 ，剛度下降13 22 ，開裂至屈服、屈服至極限荷載階段的剛度衰減規律與普通剪力墻基本一致，空心剪力墻的後期剛度比較穩定。
  3. When the pole ' s axial compress ratio is 0. 8, the load - bearing capability ' s discount coefficient is 0. 7, when the pole ' s axial compress ratio is 1. 1 ; the load - bearing capability ' s discount coefficient is 0. besides, gfrp can reform the poles " distribute of concrete cracks, increase the poles " ductility

    在軸壓比為0 . 8的時候，由於rc柱和gfrp之間存在的應力差，導致其極限承載能力的提高幅度下降至原來的70 ，在軸壓比為1 . 1的時候，其極限承載能力可以看作是沒有提高。
  4. Along with the integration level is higher and higher, the size of the device is reducing, so it needs new manufacture method to expand the limit size under 30nm

    隨著半導體晶元的集成度越來越高，器件的尺寸不斷降低，需要新的製造方法將尺寸極限擴展至30nm以下。
