optical mirror meaning in English

光学反射镜

This paper presents the experimental method to measure the high reflectivity of optical mirror by cavity ring - down spectroscopy
摘要根据光腔衰荡光谱技术原理，建立了测量镜片反射率的实验装置。
Supported financially by the national natural science foundation of china , employing the testing techniques such as optical metallography analysis , scanning electron microscope ( sem ) , electron microprobe scanning microscope ( emsm ) , transmission electron microscope ( tem ) , x - ray diffraction ( xrd ) and mechanical performance measurements ( including micro - yield strength mys ) etc . , this research has worked comprehensively and deeply on a very important issue ? the micro - yielding behavior and mechanism of beryllium material for inertial guidance instruments and optical mirrors ? which has been paid more attention to by designers since the 8th even the 7th five - year plan
在国家自然科学基金资助下，本研究采用光学金相显微镜，扫描电镜( sem ) 、电子探针( emsm ) 、透射电镜( tem ) 、 x射线衍射( xrd ) 、力学性能(包括微屈服强度_ ( mys ) )等测试技术，较详尽和深入地研究了“七五” 、 “八五”计划期间用户一直希望解决的惯性导航和光学镜体铍材一个十分重要的问题：微屈服行为及机理。
