我們已經把協調方程寫成了極坐標的形式。The paper abstracts out the palmprint mainline characteristic owing to palmprint image gradation by the gray value characteristic property method, defining the online palmprint characteristic space with the form of the polar coordinate and compressing the dimension, at last we use the neural network to accomplish the design of identification authentication system with the on - line palmprint as the mating algorithm. based on this, a fast and reliable system of identification authentication can be built
採用基於掌紋圖像灰度特性的方法提取出掌紋的主線特徵，以極坐標的形式定義在線掌紋的特徵空間並降維處理，最後用神經網路作為匹配演算法完成在線掌紋身份驗證系統的設計，以此為基礎建立了快速、可靠的新型身份認證系統。The properties of the key optical and electrical devices and the controlling mode in the system are put forwards. using the polar coordinate lines with different directions and the circulars with the same axis can be written together. by using he - cd laser ( 442nm ) as writing light source, the system can directly write line with width 05 # m on a sample
本文的主要目的是建立了一種極坐標和直角坐標相結合的激光直寫系統的原理樣機，探討系統的各部分器件的基本性能要求，為今後研製高精度激光直寫系統做好工作基礎，分析了激光直寫系統中關鍵器件的性能要求，基本控制方式，實現了極坐標方式下，任意旋轉角度直線圖形與共心圓環的光刻。This paper provides the general equations of the theoretical contour line and the actual contour line of roller translation follower and roller oscillating follower disc cam in the polar coordinates system and the rectangular coordinates system, respectively. the equations are not only fit for the different layouts of the relative position of follower and cam, but also fit for the different types of cam contour
