由此可以清晰地看出，在古生代早期全球各大陸的主要部分都位於赤道附近及南半球，大致表現為沿緯度、呈東西向排列的特徵，中國及鄰區的小陸塊群在古生代始終都處在勞倫大陸、西伯利亞與岡瓦納大陸之間；隨著西伯利亞大陸的快速北移，在勞倫大陸與岡瓦納大陸的西部地區發生南北向拼合，亞皮特斯洋和里克洋的消亡，到古生代晚期形成統一的泛大陸；而岡瓦納大陸的東部（澳大利亞和印度等）則逐漸向南移動、離散，地殼張開，構成古特提斯洋；中國及鄰區的小陸塊群則一直處在古特提斯洋中，保持離散狀態，總體上緩慢地向北運移，並逐漸轉為近南北向的排列方式，石炭紀到三疊紀才在天山興安嶺、昆侖山、秦嶺大別、金沙江和紹興十萬大山等地段發生一系列局部性的陸陸碰撞，使中國大陸地塊的大部分逐漸併入歐亞大陸。The study results display : the particle shape trends to needle more, the effective permittivity is bigger when the volume of particle is the same. the particle shape trends to penny more, the effective permittivity is bigger when the volume of particle is the same. the dimension of particle does n ' t affect the effective permittivity when the shape of particle is equal
本文的研究結果表明，對于無殼顆粒復合材料在相同的體積情況下，粒子的形狀越是趨于針形，等效介電常數越大；粒子形狀越是趨于便士形，等效介電常數越大；比較而言，便士形的等效介電常數大於針形的介電常數，而以球形的介電常數最小。It is the result of self - assembly of molecules and embodiment of dissipative structure under the imbalance state. for chondroitin sulfate ( cs ), the self - assembly behavior of cs in the presence of ca2 + is studied by afm. the result shows that cs can be formed integrated self - assembly films when its concentration exceeds 1. 0mg / ml

研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時，軸向和環向載荷的比率不同，母層和子層可能發生拉伸屈曲，也可能發生收縮屈曲，或者同時發生拉伸和壓縮屈曲;母層與子層各向異性存在差異，即泊松比與剪切模量不匹配時，將使子層板的邊界上承受壓縮和剪切作用，當分層達到臨界狀態則發生屈曲，當母層與子層的各向異性差異越大，則發生分層屈曲的可能性越大;分層損傷的屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。Different hosts " response suggested that tumv - sd1 could infect plants of 10 species in 3 families. tumv - sd1 formed pine - wheel inclusion bodies in plant cells. the coat protein of the tumv - sd1 contains 3 components whose estimated molecular weight are 45kd, 38kd and 14kd respectively
