The analysed results show that the reasonable rotating speed np and distance e between workpiece plate center and polishing plate center are 60rpm and 100mm on ultra - precision surface polishing machine with correction rings , respectively
适合钽酸锂晶片化学机械抛光的抛光盘转速为n _ p = 60rpm ，工件盘中心到抛光盘中心的距离为e = 100mm 。
The side displacement of the glass plate center is larger or less than the glass plate thickness , for the 3d geometric size of the glass plate and the lateral load vary in a wide range . in other words , the mechanic analysis of glass plate belongs to large deflection or small deflection theory in thin plate theory
由于幕墙玻璃的三向几何尺寸和横向荷载集度可在较大的范围内变动，玻璃板中心的侧向位移，有可能小于或大于玻璃板的厚度，也就是说，幕墙玻璃的力学分析，既可能属于薄板理论中的小挠度问题，也可能属于大挠度问题。
