首先以單脈沖相控陣天線測角原理為基本理論出發點,利用相位控制的坐標分離技術,基於線陣、圓形陣等簡單形式的相控陣天線,推導了平面陣、圓柱面陣等相控陣天線由相位量化誤差引起的波束指向誤差公式。If the objective lens is closer to the compact disk than the focal length of the object lens, then the cylindrical lens creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離短於物鏡的焦距,柱面透鏡就會使在光電探測器陣列上的成像變成橢圓影像。If the objective lens is further away from the compact disk than the focal length of the object lens, then the cylindrical lens again creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離長於物鏡的焦距,柱面透鏡也會使在光電探測器陣列上的成像變成橢圓影像。Their maximum and variance of beam pointing accuracy are much smaller than the results of round - off method. deficiently, only ordinary antennas are studied here, circular array and cylindrical array, for example. farther study about complex and anomalous conformal antennas is expected
不過,本文中只對簡單形式的共形陣天線,如圓形陣、圓柱面陣天線進行了分析,復雜的不規則的共形陣天線的情況還有待于進行進一步的研究。The research works finished in this paper are listed below : 1. solving the problem in testing of cylinder vessels that the sensors disposition is very rigorous, carrying out study of freewill triangle network orientation and linear orientation, bringing forward the discriminance which distinguish the validity of orientation array using character string method the first time, at the same time, solving the problems that judgement of orientation array, elimination of camouflage location, avoidance of repeat location, etc. 1 '. carry ing out the study of the orientation of defects in stand lank floor with the method of freewill planar triangle orientation, advancing bran - new discriminance on the validity of orientation arrays, orientation points, and the disposing means of the acoustic sources near sensors and those near common border

本文對板帶寬度變化的板柱結構推導了變截面直桿單元的單元剛度矩陣和等效結點荷載列陣,避免了在結構分析時所作的近似,也擴大了等代框架法的計算范圍,使工程技術人員免於使用佔用機時、難于掌握的有限元分析法。This system can not only support the algorithm based on homography matrix, but also support automated panoramic mosaicing method based on cylindrical coordinates
該系統支持基於單應矩陣的演算法和基於柱面坐標的全自動全景拼圖演算法。In this thesis, the basic operation in the optical computation was studied by analyzing the course of laser beams transmitting through a vmm, which is composed of an array of vertical cavity surface - emitting lasers, spherical and cylindrical lens, an array of multiple quantum well spatial light modulators and an array of the detectors
本文研究的光學矢量-矩陣乘法器主要是由垂直腔面發射激光器( vcsel )陣列、球面透鏡和柱面透鏡組、多量子阱空間光調制器( mqwslm )及ccd陣列構成。作為小尺寸的集成光學器件,必須要考慮衍射的作用。This silence was broken by one of the brothers who, leading pierre to the rug, began reading out of a manuscript book the interpretation of all the figures delineated upon it : the sun, the moon, the hammer, the balance, the spade, the rough stone and the shaped stone, the past, the three windows, etc. then pierre was shown his appointed place, he was shown the signs of the lodge, told the password, and at last permitted to sit down
有個師兄打破了這一陣沉默,他把皮埃爾領到地毯前面,開始從筆記本中給他念出地毯上繪制的圖形日月槌子鉛錘鏟子立方形奇石柱子三扇窗子等的說明文字。之後他們給他指定一個座位,把分會證章拿給他看,告訴他入門的暗語,最後允許他坐下。分會會長開始宣讀分會章程。The directivity coefficient of the phased array antenna has been generalized and discussed. according to the formulations of microstrip antenna design theory, planar and cylindrical microstrip patch cell has been analyzed. we can conclude that the cylindrical microstrip patch cell has the performance of high gain, low thickness, high resonant frequency, uniform directivity diagram, and easy fabrication on missile body, so it is a good choice
