摘要
本文利用球面各点到球心的距离相对不变的基本原理，在一个高精度的二维旋转支架上测试球面壳窗的同心度。其测试精度小于0．03mm。完全能够满足球面壳窗同心度的测试。
In this paper, using the fundament of relative distance being unchanged from eachdot spherical surface to center, we measured for the window of spherical suthee on a spin-stand of twodimensions. Measuring accuracy is less than 0.03 mm. It satisfied the demand of measurement ofconcentricity for window of spherical surface.
