  1. The author suggests that the three lithosphere - scale faults, lancangjiang fault, jinshanjiang - ailaoshan fault and axis fault in the middle of the basin, are the main geological structures that control the formation of basin, magmatism and metallogenic congregate district. the anticline structure with an axis of triassic strata and the related fault system within the basin, and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields. junctions of two or more faults with different orientation, interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies

    認為瀾滄江斷裂、金沙江-哀牢山斷裂及盆地中軸斷裂這三條巖石圈斷裂是主要的控盆-控巖(巖漿巖)構造及礦集區尺度的控礦構造;盆地中以三疊系為軸的背斜構造及相關的斷裂系統、盆地西南緣公郎弧構造等是礦田尺度的控礦構造;多組斷裂的交叉、層間破碎帶及地層中的氧化還原界成礦體的有利部位。
  2. In the course of working, , the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly

    與單向犁相比,其優點在於:耕地無開、閉壟,地表平整,降低了耕后整地的能量消耗,減少了地頭的空行程,因而大大提高班次生產率。為了滿足犁體梭式作業的要求,我們採用了一隻小容積雙作用的液壓油缸;同時對犁壁曲狀採用了近似圓的對稱設計。但經過一段時間的田間試驗,我們發現:該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發生了斷裂,造成整個犁體無法正常工作。
  3. Parabolic - shaped collector

    拋物聚光
  4. The conformal microstrip antenna with some unique character has been applied in many fields, especialy on speedy objects. in this paper, an efficient fdtd algorithm is introduced to analyse the microstrip antenna. firstly, the fdtd formula in descartes coordinate system and in cylindrical coordinate system are obtained from the time _ dependent maxwell equations using the yee algorithm in a calculating region where the dielectric parameters are independent of time and space. the choice of the space discretization units and the time discretization interval are discussed which are decided by the accuracy and stability respectively. the shape and setup of the excitation source are discussed too. the excitation source is chosen to be gaussian pulse in shape. secondly, the mur ' s first - order and second - order boundary condition are deduced in cylindrical coordinate system. the methods of transforming radiation fields from near zone to far zone in the frequency domain and in the time domain are presented when fdtd is applied to analyse the characteristics of far zone. finally, three kinds of microstrip antennas are analysed. they are a slot antenna that lies on a plane ground of a microstrip, a slot antenna that lies on a cylindrical ground of a microstrip and a microstrip line _ fed aperture coupled stacked rectangular patch antenna in cylindrical coordinate system

    本文從麥克斯韋旋度方程出發,建立了笛卡兒坐標下無源空間中均勻無耗媒質的fdtd基本方程和圓坐標下無源空間中均勻無耗媒質的fdtd基本方程,詳細討論了fdtd法計算中時間步長和空間步長的選取原則以及激勵源的類型和設置;推導了mur一階和二階邊界條件在圓坐標下的差分格式;給出了在用fdtd法計算天線的遠場輻射特性時必需採用的頻域和時域近場遠場變換技術;最後用fdtd法計算了平微帶縫隙天線、微帶縫隙天線和微帶層疊天線的輸入阻抗和遠區輻射場,並分析了天線的一些參數的變化對天線輸入阻抗的影響,得出了一些有用的結論。
  5. Those models express the panoramic image in different ways. in our system, we adopt planar manifold as our reprojection model of panorama, and adopt cylindrical manifold as our panoramic qtvr reprojection model
