    定義了立方角錐棱鏡的有效反射區，證明了立方角錐棱鏡底面角部區域（即非有效反射區）入射光與出射光不平行，並且在入射光垂直棱鏡底面入射情況下計算得有效反射區的面積為底面的三分之二。
  3. 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。
  4. Seismic survey is a new method used to civil engineering area in recent years. it was widely applied to survey or detecting of roadbase, dam base, foundation of building, tunnel, river bed, lake bed and etc. the chief methods are reflection method, refraction method, wave velocity testing, surface ware survey and transverse wave suivey. seismic survey can divide different layer, measure the incidence of sediment stratum, detect the structure of rock, test the handle effect of surface wave survey, we can calculate the carrying capacity of foundation and other mechanical parameters. this technique can give service to some big engineering departments such as highway developing company, survey design company, water supply company, plan bureau, construct bureau etc

    應用於工程的主要方法有反射波法折射波法波速測井面波法及橫波勘探等。地震勘探能詳細劃分地層高精度地確定沉積地層的傾角能夠準確探明巖體構造褶皺斷層破碎帶裂隙帶對于回填工程路基壩基，地震勘探可以檢測其回填處理效果對于隧道工程，可以探測隧道洞體的圍巖分類及洞口地質情況利用面波勘探所得到的瑞利波速度，可以準確推算地基的承載力動彈模量等力學參數。
  5. Abstract : constant components and output opened ports in the result of high - level synthesis lead to explicit redundancy in gate - level technology mapping. explicit redundancy can not improve the performance, but increases power consumption, enlarges circuit area and decreases its testability, so it should be removed. this paper proposes a queue loop optimization algorithm to remove explicit redundancy completely which decreases the circuit area and improves the testability

    文摘:高級綜合結果中常量元件和輸出懸空埠導致門級工藝映射結果中存在顯式冗餘.顯式冗餘無助於提高電路性能，反而增加功耗，降低電路的可測試性，使電路面積增大，應予消除.文中提出了顯式冗餘的隊列循環優化演算法，完全消除了此類冗餘，從而有效地減少了生成電路的基片面積，提高了電路的可測試性
