  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、四軸聯動的控片銑銑削加工方法.由於燃燒室外表面的母線輪廓復雜,手工編制控加工程序難度大.為了解決控加工程序的編制問題,研究了斜航線的學模型,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選擇、銑削方式和方向、具調整和起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考意義
  2. Field germination, nodulation status and physical growth parameters of seedlings ( shoot and root length, vigor index, collar diameter, leaf number, fresh and dry weight of shoot and root and total dry biomass increment ) were recorded after three and six months of seed sowing

    播種的3和6月後,記錄幼苗大田發芽、分枝狀況和其他物理生長(枝條或根長、活力指、莖、葉片、分枝或根鮮重和干重、總的生物量干重增長)等。
  3.

    結合密集波分復用系統的光束耦合特點,提出用菲涅爾透鏡列陣做光纖陣列準器,並設計不同結構的透鏡列陣,得出了該陣列準器的光束耦合損耗特徵,與現有的光纖準器的相比,體現出用菲涅爾透鏡列陣作陣列光纖準器的諸多優勢。
  4. It is very important to estimate the basic parameters in helicopter preliminary design. neural network ( nn ) has the advantages in estimating accuracy and generalization over traditional methods. however, there are some difficulties in using nn, e. g., how to select a proper network structure and the number of hidden layers. in this paper, structure and connection weight of a three - layer nn are optimized by genetic algorithm, and the optimized network is applied to helicopter sizing. the proposed method can not only give an optimal nn structure and connection weight, but also reduce the prediction error and has the capability of self - learning when the latest data are available. furthermore, this method can be easily applied to helicopter design systems

    升機初步設計階段估算其基本是很重要的.神經網路的通用性和精度比傳統的估算方法有更多的優勢,但是在應用神經網路時存在如何選擇合適的網路結構和隱層節點目等一些困難.應用遺傳演算法優化三層神經網路結構和連接權重,並將優化得到的網路應用於升機選擇中.該方法不但可以給出一個最優的神經網路結構和連接權重,而且降低了估算誤差,具有及時應用最新據學習的能力.此外,該方法易於在升機設計系統中得到應用
  5.
