The pictures were taken by normal case photography method, and the relevant Angle was gotten by digital theodolite.
该方式是一种近景摄影测量方式，采用正直摄影方法获取影像，用电子经纬仪获取相关角度信息。
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?
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?。
The existing algorithms include equivalent left and right curve Angle by definition, normal section line method and tangent projection etc.
有关的算法有根据定义的左右曲面角相等，法截面法和切向投影等。
This new method is a non-contact measurement and it can avoid any interference in the spray field. At the same time, it can reduce the normal errors in manual measurement of spray angle.
该方法实现了喷雾角的非接触测量，避免了常用方法对喷雾现场的干涉，减少了人工测量方法带来的误差。
