水平移动偏差导致传力杆不可接受水平为1.8%，而竖向偏转偏差导致传力杆不可接受水平高达15.8%。
Horizontal movement could result in the unacceptable level of 1.8%, and the vertical deflection could cause the unacceptable level as high as 15.8%.
采用有限元分析法对不同固定方式下镜面热变形进行分析，结果表明：镜体释放热应力前后的法向角度偏差可达近3个数量级；在合理采用压板固定方式后，镜面法向偏转角度在10?。
Applying finite element method to analyze shows that normal angle deviation of mirror body before and after thermal tension being released can be nearly 3 order magnitude which is 10?
