landing of beam 中文意思是什麼
landing of beam
解釋
電子束射擊點-
Part 2 analyses beam landing shifts made by thermal deformations of a shadow mask and vibration of a new type of shadow mask - aperture grille. an automatic measurement system for cpt decolorization and a vibration measurement system for aperture grille are established. part 3 analyses the difference of perception and discrimination to color between the human eyes and ccd system, and develops a new method based on ccd technology to evaluate the screen white - balance
主要內容分為三部分： （ 1 ）分析著屏電子束分佈與電子槍、偏轉系統及蔭罩之間的關系，研製自動測試裝置，為設計和改進相關結構提供依據； （ 2 ）分析蔭罩熱變形和振動對顯示屏色純度影響，建立了色純漂移自動測試裝置和張緊式蔭罩振動測試系統； （ 3 ）分析了人眼與ccd對彩色刺激的不同響應，建立了基於ccd的顯示器全屏色純均勻性測試方法。 -
Aberration of electronic lens made by electron gun and aberration of magnetic deflection system made by dy are comprehensively investigated, so is the shadow mask ' s effect on electron beam landing screen error. the conclusion can be get that, because the distribution of electron beam landing screen ( distribution of luminance ) is affected by many kinds of factors, it cannot get the correct function by calculation, and should be get by measurement instead
全面分析了cpt電子槍發射系統形成的電子透鏡像差與磁偏轉系統形成的偏轉像差；分析了蔭罩的自身厚度與位移對電子束著屏的影響，並由此得出結論，著屏電子束分佈（即亮度分佈）受著許多因素的影響，理論分析是半定量的，著屏電子束分佈需要用精確的測量儀器來測量。 -
By using auto - adjusting boundary conditions and the method of three cubed spline curve fitting, the system software can recover both of the horizontal and vertical beam profile. the measurement system can also measure the beam landing screen error of cpt. it provides a important measurement and analysis tool to improve the performance of electron gun and dy, and improve the definition of cpt
系統軟體中，提出了採用動態確定邊界條件，通過對離散采樣點的三次樣條插值曲線的擬合恢復束斑x和y方向的輪廓，本系統既能準確客觀地描述電子束輪廓，又能夠準確快速地測量電子束著屏誤差等多種參數，為cpt電子槍和偏轉系統的性能改進與解析度的提高提供了有力的測試分析和研究手段。
