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Second, proposing a hybrid recommendation strategy which used multi - agent system, collaborative filtering, and top - n together to generate right recommendations for customers in different profitability tiers. in the first part, we have defined customer value from two categories : intrinsic value and network value. based on customer ' s historical behavior, segment them with considering their recency, frequency, and monetary
明確指出高價值客戶可體現在兩個方面：一是具有高自身價值的客戶，二是具有高網路價值（客戶的網路影響力）的客戶；其次，由顧客的歷史和當前行為，特別是從recency （最近訪問時間） 、 frequency （訪問頻度） 、 mon6t8ry （購買投人）因素出發，進行顧客內部價值挖掘：並通過形式化顧客的網路價值，給出完整的分層演算法和相應實驗。Due to the moving base existence of the minehunting and the frame structure characteristic of the sonar array, a new modeling thought in which the boat body coordinates is regarded as moving coordinates and the whirligig equation of sonar array compared with the self coordinates is founded on the basis of the euler ' s theorem and the coordinate transform is introduced. the dynamic equations of minehunting sonar array with the state matrix form are founded by settling the dynamic models with the vector form. so it offers theory foundation for analyzing the dynamic characteristic and designing robust control
由於獵雷艇作為動基座的存在和聲納基陣的框架結構特點，提出了以艇體坐標系為運動坐標系，運用變形的歐拉定理和坐標變換建立聲納基陣相對自身坐標系的旋轉運動方程的建模思想；將所建立的矢量形式的動力學模型展開整理，獲得了狀態矩陣形式的獵雷聲納基陣動力學方程，為系統動力學模型的實用化奠定了基礎。21st century today, it is one that appreciate way read and write era to interpretting blueprints brand - new era who era strides forward, press photographer body shoulder important task, continue and take on news gathering and editing the subjects of team, but not the supporting role, make them catch down the transient scene the camera, thus the change of noting history, make us able to experience life intactly through the vision image, this needs press photographer to jump out the convention, involve " digitalization ", humane care, the ideas of common people ' s visual angle, theory, etc. of planning are changed, keep the sober head constantly, occupy and endanger and think of fitting, rouse oneself and study, have the courage to bring forth new ideas, may just surmount others, surmount oneself, it weeds out the old and bring forth the new in barges strive media competition that flow take more good worthying of the newses photography fine piece of writing of eras
二十一世紀的今天，是個欣賞方式由讀寫時代向讀圖時代邁進的嶄新時代，攝影記者身肩重任，能否繼續擔當新聞采編隊伍的主體，而不是配角，使他們用相機捕捉下了稍縱即逝的場面，從而記錄下歷史的變革，通過視覺形象使我們能夠完整地感受生活，這就需要攝影記者跳出舊框框，涉及到「數字化」 ，人文關懷、平民視角、策劃理念等方面的觀念轉變，時刻保持清醒的頭腦，居危思安，奮發學習，勇於創新，才可能超越別人，超越自己，推陳出新，在百舸爭流的傳媒競爭中拍出更多更好的無愧於時代的新聞攝影佳作。Furthermore, it is a departmental law attached to the constitution, just like the civil law, the criminal law, the labor law, etc. the properties of the social security law should include : it is regarded as the public law, not the fusion or combination of the public law and private law. it is the human being law showing the spirit of humanitarian. it protects the existing rights, guarantees people ' s basic existing and life
其理由如下：第一，從調整對象看，社會保障法有其獨立的、特殊的調整對象；第二，從法規數量看，已頒布的法律文件已足夠構成一個法律部門；第三，從法規內容看，涉及社會保障方面的法律、法規也可形成一個法律部門體系；第四，從調整方法及對違法行為的制裁形式看，社會保障法有它自己的特色。The review suggested a progressive approach to improving the regulatory framework. it favoured a self - regulatory approach, under which the market would draw up codes of practices and monitor their compliance, with the hkma facilitating and overseeing the overall process
檢討建議以循序漸進形式加強本港的監管工作，並贊同採取自我監管模式，由市場自行制定經營守則及監察參與者遵守守則，並由金管局負責監察整體模式的執行。Traditional inertial mechanized - platform uses velocities to damp the system attitude to improve the precision of attitude, when the system acceleration is small. referring to the idea, this paper designeda damp kalman filter in strap - down attitude heading reference system ( ahrs ). the new method makes use of 3 - d accelerometer ' s measurements to estimate the system attitude, which is measured to compensate attitude errors. because the acceleration affected the precision of fiher directly, the fuzzy adaptive system was presented. the fuzzy logic inputs are three accelerations and the output is to control the measurement noise covariance matrix. simulations and experimental results prove that the damp algorithm can damp most of schuler oscillation and foucauh oscillation, so that to assure the filter convergence and efficiently improve the precision of strap - down ahrs
在系統機動性不強的情況下，傳統的平臺內阻尼演算法將系統本身的速度信息通過阻尼網路加到系統中，達到提高姿態角精度的目的.將這種平臺內阻尼的思想引入到捷聯慣性航姿系統中，在系統加速度較小的情況下，利用加速度計的輸出估計系統姿態角，通過卡爾曼濾波的形式補償系統姿態誤差.由於加速度的大小直接影響濾波器精度，本文設計了模糊自適應卡爾曼濾波演算法，根據三軸加速度計的輸出調整內阻尼量測誤差方差陣，從而避免了濾波器的發散.模擬和實驗驗證，內阻尼演算法可明顯抑制舒勒周期振蕩和傅科周期振蕩，避免了系統姿態漂移，有效提高了捷聯慣性航姿系統的精度Funds are allocated in one - line to give budget - holders flexibility in the use of resources, in much the same way as the allocation of block grants by governments to universities in some countries
