  1. Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly. because the width dimension of loxodrome groove is narrow and the depth is deep, some machining methods are incapable, such as end - milling or electrochemistry. according to the peculiarities, a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched. because most firebox generatrix is composed of complex curves, it is very difficult to get cnc cutting program with manual means. in order to deal with the problem, the loxodrome mathematics model is studied, and an auto - programming software system is developed. the software system can generate cnc cutting program of loxodrome on many kinds of turned surface. the constriction - distension segment of firebox is the most representative workpiece. the sharp changing of its generatrix slope makes loxodrome milling difficult. with the theory analyzing and practice cutting experiment, some applied techniques, which include milling mode and direction, choosing cutter diameter and cutting start point setting, are developed. adopting the technology above, tens regular workpiece have been manufacturing. the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method. the developed technology is also worth to be referenced to other similar workpiece

    將液體火箭發動機燃燒室的冷卻通道設計為斜航線（等傾角螺旋線）槽形，可以大幅度改善燃燒室的冷卻性能.斜航線冷卻槽的槽寬尺寸較小而槽深尺寸較大，所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點，提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母線輪廓復雜，手工編制數控加工程序難度大.為了解決數控加工程序的編制問題，研究了斜航線的數學模型，開發了自動編程軟體系統.使用該系統，可以生成多種母線輪廓回轉體外表面上的斜航線數控加工程序.燃燒室收斂-擴張段的母線斜率變化大，加工難度大，是斜航線冷卻通道加工的最典型工件.經過理論分析和實際切削實驗，研究了針對該類型工件的片銑刀直徑選擇、銑削方式和方向、刀具調整和起刀點的設置等多項實際的加工方案.採用上述的一系列技術，已經成功地加工了數十個合格工件.經過兩年多的實際生產過程應用，驗證了所開發的斜航線冷卻通道加工方法的正確性和可行性.這些加工技術的研製成功，對其他相似類型零件的加工亦具有參考意義
  2. Vanadium is important and valuable in steel - making, electronic production and national defence industry etc. now, the operation pattern of refining vanadium in our nation is based on human experiences, and the automation degree is still at a low level. operation mode based on human experiences is one of the main reasons make the quality of semi - steel and vanadium product unstable. in developed contury such as russian, static model was used to control the process of vanadium refining

    我國目前的轉爐提釩為人工操作模式，由操作人員根據經驗和感覺進行操作，自動化水平低，存在著釩渣質量和半鋼質量不穩定的問題；在國外，俄羅斯等一些國家已經在使用靜態模型對提釩過程進行控制，取得了較好的效果，但是這些模型大都是根據復雜的物理化學規律研製的機理模型，要求有非常穩定的生產流程和工藝條件，對于鐵水成分、生產設備等變化的適應性差，不但移植困難，而且模型價格異常昂貴。
  3. Basing on the thorough research and analysis of several essential technologies, we have implemented identity authentication, illegal link, network security aduit and anti - virus detection etc. we used digital certificate to accomplish identity authentication which was based on the study and analyzing of all kinds of authentication. in regard to network security audit, we mainly researched on the distributed model of network security audit and the audit strategy of the rule library. in view of the traditional rule library ’ s flaws, with the formalizing description of audit rule, we proposed a dynamic security audit strategy model which was based on the nature deduction system
