  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. Reduction crack in the pumping transfer concrete during the megathermal climateit is a diffcult problem. the unit undertaking project of no : 4 pump station for diverting water from the south to the north make a beneficial explore form the design of mix proportionging, control and the concret placing temperature to control the crack extension those experience can be referenced by the unit in charge of large scale pumping station project

    摘要高溫季節泵送混凝土裂縫控制的當前工程界一個難題，南水北調淮安四站工程建設中，建設單位科學安排、精心施工，從控制混凝土配合比、入倉溫度等多方面著手，對混凝土裂縫控制技術進行了有益的探索，並取得了預期的效果，為混凝土抗裂技術積累了經驗，對同類型泵站的施工具有重要的參考意義。
  3. Case is an instance of something in law, an example of some decisions that proved to be successful or failure. it concludes from the experiences and knowledge that have happened and is the record of useful knowledge which can help to gain our ends. with a lot of characteristics, for example, authentic contents, referenced decisions, elicitations while solving problems, it has been widely implemented in the fields of law, scientific decision, problem diagnosis

    案例是某類案件的例子、某種決策成功與否的例子，是對以往經驗知識的歸納整理，為達到某種目標所需要借鑒知識的記錄，其具有內容的真實性、決策的可鑒性及處理問題的啟發性等特點，廣泛應用於法律、科學決策、問題診斷等方面。
