  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,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.針對這些特點,提出了五軸控制、四軸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難度大.為了解決數控加工程的編制問題,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.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.採用上述的一系技術,已經成功地加工了數十個格工件.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. Adopting the actual county - grade database of land use firstly founded in china, combining with the comprehensive influential factors of land use change, using the correlative statistic software and the mathematic analytical methods ( principal component analysis, gray relating analysis, multivariate time series markov chain analysis, multivariate regression analysis, gm ( 1, 1 ) gray model, gray series gm ( 1, n ) model methods etc ), this paper analyses the dynamic change of land use and driving force in jiang ' an county qualitatively and quantitatively. the results indicate : 1 the land resource per capita and the area of single - land - use type in jiang ' an county are not prior to other places in yibing city or sichuan province. however, the terrain is dominant in choosing the way of land use

    本文採用全國首批建立的「縣級土地利用現狀數據庫」的基礎數據,結影響土地利用變化的經濟、社會、環境等綜因素,採用相關分析軟體( dps 、 spss )和數學分析方法(主成分分析、灰色關度分析、多元回歸分析、多元時空馬爾柯夫鏈分析、 gm ( 1 , 1 )預測模型分析、灰色gm ( 1 , n )模型分析等方法) ,對江安縣土地利用變化及其驅動力進行定性、定量研究,研究結果表明: 1江安縣人均總的土地資源數量和單一土地利用類型的數量在宜賓或四川省區域內均無優勢;地對土地利用方的選擇起著主導作用;土地利用變化的總趨勢是:耕地、林地、交通用地和水域面積不斷減少,居民點及工礦用地和未利用地面積不斷增加;景觀多樣性指數呈現「 」趨勢。

  4. What the practical problems is often gotten is a single variable time series which has a time interval of t, reflect by a lot of interactive physics factor, containing the mark of all variates participating in movement, traditional time series analysis is to analyse going from this array to the form directly it ' s time develops, one dimension analysis loses useful information, the characteristics of phase space reconstruction method is to construct one dimension scalar quantity to high dimension vector, prop the geometry space of the state, show all dynamical information of system in phase space. the characteristic that just constructs again according to the phase space in this text, analyse the time series of responding, use the relevant knowledge of symbol dynamics and reconstruct phase space, put forward a kind of relation degree analysis method of the systematic mathematics model which has theory basis, so reach the correction of calculation mathematics model, make it accord with the actual systematic state

    實際問題中常常得到的是一個時間間隔為t的單變量的時間,它是許多物理因子相互作用的綜反映,蘊藏著參與運動的全部變量的痕跡,傳統的時分析是直接從這個地分析它的時間演變,一維分析必然喪失許多有用信息,相空間重構方法的特點是把一維標量數據構造成高維矢量,支起狀態的幾何空間,在相空間中展示系統全部動力信息。本文正是根據相空間重構的特點,對響應時間進行分析,利用符號動力學、重構相空間等方法,提出一種有理論依據的系統數學模型關度分析方法,從而達到修正計算數學模型,使其更符實際系統狀態的目的。
