在單向激光掃描檢測技術的基礎之上，提出了一種雙向激光掃描檢測系統，其採用激光掃描檢測技術與特殊光學系統相結合，用準直半導體激光掃描光束對被測工件徑向某一截面的兩個相互垂直方向同時掃描，經掃描接收光學系統、高速光電變換、電子學系統和微機數據處理系統，對將攜帶有垂直方向被測量信息的光束進行處理，實現了回轉體工件同一截面兩個垂直方向的徑向尺寸和橢圓度等參數的非接觸自動測量，解決了同時非接觸測量回轉體零件同一截面兩個徑向尺寸的難題，它具有高速，高精度和非接觸自動測量等特點。In the paper, based on the method of low pair replacing with high pair, the problem of cam design was transferred to that of linkage design. by means of rotary unit vectors, the equations of displacement, velocity and acceleration of the replacement mechanisms were developed. and then, the virtual linkage ' s length and direction were deduced
論文基於高副低代原理，將平面凸輪機構設計與再現函數的平面連桿機構設計統一為同一種方法，運用圓向量函數建立代換機構的位移、速度、加速度矢量方程式，求取虛擬連桿桿長和方向，由此展開凸輪理論廓線、實際廓線、曲率半徑和壓力角的求解，並得出用圓形刀具加工凸輪時刀具中心的軌跡方程。The kinematics analysis of the moving system of lunar rover is presented in this paper. in this procedure, the lengthways speed of each wheel, when the lunar rover is moving in common status, are calculated. moreover, the same direction and converse difference steering for difference steering system with steering radius as the critical transfer condition is put forward
本文首先對六輪獨立驅動式月球車所採用的行走系統進行了運動學分析，推導了月球車正常行駛狀態下各車輪的縱向速度，並給出以轉向半徑為臨界值的差速轉向系統的正、反向差速的轉換條件。But the sound field generated by this kind of transducers in medium has s ome " congenital " shortcomings : there always exist zero areas in sound - axes of near - field however we change the frequencies and radii of transducers, so we need to look for better radiate transducers. in this dissertation, we design and make two kinds of radiate transducers : bunchiness control transducer with electric polarity division and gaussian transducer
然而，這種類型的換能器在媒質中產生的輻射聲場，有其「先天性」的不足之處，在近場中無論平面活塞的頻率和半徑如何變化，軸上和沿徑向上都呈現出極大和極小交替分佈的干涉現象，因此我們有必要繼續尋求更為理想的輻射形式。According to the fact that iris images cannot be compared for their different resolutions, a new method for normalizing iris region into fixed resolution by using minimum inner boundary resolution and minimum radius difference of inner boundary and outer boundary is presented
摘要針對虹膜區域圖像大小不同，難以實現虹膜的比較問題，提出了根據虹膜最小內邊界周長確定角度解析度和根據虹膜最小內、外邊界半徑差確定徑向解析度的方法，將不同分辨的虹膜圖像轉換為相同解析度的矩形區域。分享友人
