Absolute measurement and foundation of standard optical surface.
标准光学面形的建立与绝对检验。
The problems existed in the standard are that the accuracy of capacity table is low, the optical measurement system is directly listed in the standard without any site comparison trial.
存在问题主要表现在容积表精度低、导轨光学径向测量仪没有经过现场对比试验就直接列入规程等。
