How to design the best support of the mirror to ensure the highest accuracy of the mirror surface, which is very significant for the optical and image system of the astronomical telescope.
On the base of relative data of the maximal deformation, studied the factors that effect the deformation of reflector surface of small telescope with bottom support.
在取得的相互关联的最大镜面变形数据基础上，研究了影响小口径反射镜底支承镜面变形的因素。
