There is uprightness inspection after the primary assemby and the final assembly of the fhree axis of evry machine to ensure tfhe uprightness between evry two axis
每一臺機器皆經初組裝三軸檢測，與后組裝三軸檢測，確保每一臺機器的三軸垂直度精確。 -
Like the primary mirror, the eyepiece has an optical axis, and this axis should be aimed at the center of the main mirror for best performance ? though in practice it is the center axis of the focuser drawtube that you aim at the primary mirror
目鏡和主鏡一樣也有光軸，光軸應該對準主鏡的中心? ?盡管實際上，目鏡的光軸對準的是調焦筒（相當于調焦座）的中心。 -
Step 2 : here you adjust the tilt of the secondary mirror to aim the focuser ' s axis at the center of the primary
現在你已經調整了副鏡的傾斜程度，把調焦座的中軸已經對準了主鏡。 -
The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
本文主要分析了三偏心蝶閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。
