錐度驅動應力型緊固件.彎頭斜鍵鍵槽尺寸和應用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Yingxian wooden pagoda has favorable aseismatic capability, as it used similar modern core - in - core structure, and fixed many batter brace make it become modern rigid reinforced floors in every hidden floor, and slope of bearing post made it that the level and uprightness frame integrate tightly. under the deadweight, every structural floors form centripetal force. those earthquake resistant measures resist many the strong destroy of earthquake in history
由於木塔採用了唐代殿堂內、外分槽的結構形式，用兩層柱圈構成筒體，並逐層加設了層高較低稱為平坐的剛度加強層，再加上兩圈柱子都由下至上向內傾斜對筒體形成環箍力，這些措施幫助木塔抵抗了多次強烈地震而未倒。Based on the hydrodynamic energy transport model, the influence of variation of negative junction depth caused by concave depth on the characteristics of deep - sub - micron pmosfet has been studied. the results are explained by the interior physical mechanism and compared with that caused by the source / drain depth. research results indicate that with the increase of negative junction depth ( due to the increase of groove depth ), the threshold voltage increases, the sub - threshold characteristics and the drain current driving capability degrade, and the hot carrier immunity becomes better in deep - sub - micron pmosfet. the short - channel - effect suppression and hot - carrier - effect immunity are better, while the degradation of drain current driving ability is smaller than those with the increase of depth of negative junction caused by source / drain junction shallow. so the variation of concave depth is of great advantage to improve the characteristics of grooved - gate mosfet
基於能量輸運模型對由凹槽深度改變引起的負結深的變化對深亞微米槽柵pmosfet性能的影響進行了分析，對所得結果從器件內部物理機制上進行了討論，最後與由漏源結深變化導致的負結深的改變對器件特性的影響進行了對比.研究結果表明隨著負結深（凹槽深度）的增大，槽柵器件的閾值電壓升高，亞閾斜率退化，漏極驅動能力減弱，器件短溝道效應的抑制更為有效，抗熱載流子性能的提高較大，且器件的漏極驅動能力的退化要比改變結深小.因此，改變槽深加大負結深更有利於器件性能的提高Hot rolled steel channels - part 1 : taper flange steel channels ; dimensions, masses and sectional properties

因拍門簡單、可靠，與虹吸真空破壞截流閉鎖方式相比，可以縮短出水管道（流道）長度，並利於泵系統起動，與快速閘門相比，拍門也有諸多優點，閘門門體易關閉不到位或卡住不能活動，因為門槽和?塊較軸孔容易殘留異物，閘門門體克服滑動阻力不僅無機械增益，且阻力和動力不在一直線上，門體易傾斜而自鎖，而拍門的工作可靠性則遠高於快速閘門。Construction machinery and equipment. high strength square taper washers for slot section
