  2. 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

  3. 3. the solution for the distribution of potential internal the dielectric ellipsoid has been obtained by means of ellipsoidal coordinates, and has obtainted the expression of the polarization field strength in the dielectric ellipsoid, calculated the included angle value of polarization vector and the external field vector, making programe to compute to get the relation shetch between the included angle value of polarization vector and the external field vector and we have discussed the result and hold that the direction of polarization field strength with that of the external field don ’ t always strict antiparallel

    二、討論了帶電粒子在均勻電磁場中的相對論運動規律。三、討論了在均勻電場中電介質橢球體的極化規律。證明了電介質橢球內的極化場強方向與外電場方向並非嚴格相反，只有當外電場與電介質橢球的某一主軸平行或者當橢球體三半軸的大小都相等時，極化場強方向與外電場方向才嚴格相反。
  4. The paper has made detailed observation by the existing apparatus and the field observation stations. based on the image and the vector database of the yutian oasis, the study has obtained the precise coordinates of investigation points by gps technique, and overlapped them with the images. after classifying the images with the maximum likelihood supervised classification method, we import the result into cis software, and analyze the yutian oasis changes about land cover " s quantity, quality and spatial position from 1976 to 2001

    本文利用現有儀器設備和野外觀測網站進行詳細觀測，在建立於田綠洲圖像庫和矢量數據庫的基礎上，運用gps技術取得野外考察樣點的精確坐標並與研究區各時期影像疊加，對影像進行了最大似然法監督分類，並將分類結果轉入gis軟體處理，全面分析了1976年至2001年該綠洲的土地覆蓋類型數量、質量與空間上的變化。
  5. By analying the requirement of traction characteristics of rectifier in ac drive reciprocal power - fed test system, in this paper, the research on high power supply quality rectifer is conducted around topology and mathematical modeling, high power supply quality rectifer ' s control methods are summarized. predicted current control based on space vector pwm in two - phase stationary coordinates is proposed and used in this paper

    本文分析了交流傳動互饋試驗系統牽引特性對整流電源的要求，對高供電品質整流電源的拓撲結構和數學模型進行了研究，總結了高品質整流電源的控制方法，闡述了本文採用的兩相靜止坐標系下基於空間矢量脈寬調制的預測電流控制方法。
