  1. Through the experimental research, we think : the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam, however, if use elasticized capacity to solve blending technological problem. adjust the breed of fiber silk, extend its diameter, its paving capacity is still worth exploring, asphalt - rubber macadam structure lager have good deformed - become capacity and crazed - resistance capacity, small gap rate. good water - resistance capacity, good hot - stability and simple construction technology. therefore. pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue. and is the good structural measure of preventing half - rigidity grass - roots unit shrink - rift reflecting. pave a thin layer of pitch rubber spall between asphalt - type pavement layer and half - rigidity basic level, although the cost of building is higher than paving togongbu in the middle, the construction technology, crazing - resistance and water - resistance are better than togongbu, not only could reduce greatly the reflex of half - rigidity grass - roots unit material, long then the use lifespan of pavement, but also it is possible to reduce suitably the thickness of asphalt mixture layer, though the cast of building in the early days becomes more, in the long - term opinion, it have fully important technological and economical significance

    通過試驗研究認為：玻璃纖維瀝青碎石的技術性能不如瀝青碎石好，但路用彈性性能較好，如能解決拌和工藝問題，調整纖維絲的品種，增大其直徑，其路用性能仍值得探討，瀝青橡膠碎石結構層具有變形性能和抗裂性能良好，空隙率小，防水性能好，熱穩定性較好，施工工藝簡單的特點，因此，瀝青橡膠碎石是二級及二級以下公路因疲勞而開裂的瀝青路面的良好罩面材料，也是防止半剛性基層收縮裂縫反射的良好結構措施，在瀝青類路面面層和半剛性基層之間夾鋪瀝青橡膠碎石薄層，雖然造價比夾鋪土工布高，但其施工工藝，抗裂性能和防水性能均優于土工布，不僅可以大大減少半剛性基層材料的反射裂縫，延長路面使用壽命，而且可能適當減薄瀝青混合料面層的厚度，雖然初期造價有所增加，從長遠來看，具有十分重要的技術和經濟意義。
  2. At first, modeling of these divvies by rate equations to obtain expressions for threshold and slope efficiency is given. on the case of this theory, the large numbers of literatures and datum are consulted, and the laser is home studied. through rationally selecting and improving the reflector surface, ensuring the beam quality, increasing farthest the absorption path, and improving effective pumping frequency ; through designing the water cooler of yag bar, the volume of laser is half the same internal and international production, and the output power is get to the extremum of the same international production

    並在此基礎上查閱了大量文獻和資料，對該種激光器進行了深入的研究，通過對yag棒直徑的合理選取併合理地改進反射鏡面，從而既保證了光束質量又最大限度的增加了吸收長度，有效的提高了泵浦效率；在不影響泵浦的前提下，通過有效縮短yag棒的長度減小輸出損耗；對yag棒的水冷系統進行優化結構設計，使激光器體積減小到國外同類產品體積的一半，而輸出功率已達到國外同類產品的極限值。
  3. With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress

    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。
