次镜 meaning in Chinese
secondary mirror
Examples
- This mirror is either the secondary mirror or another , smaller one interposed between the secondary and the detectors
这个修正镜可用次镜，或是置于次镜与侦测器之间的更小镜子。 - The optical system is optimized to achieve 0 . 1 u m resolution over a o . lmm diameter image field of view and the mirrors of the objective were coated with mo / si multilayer to provide 45 % reflectance at near - normal incidence angle for 13 . 0nm radiation
经优化设计后， 0 . 1mm像方视场内的成像分辨率优于0 . 1 m ；近正入射条件下， schwarzschild微缩物镜主、次镜mo / si多层膜的实测反射率为45 。 - The prototype is made by a concave sphere primary and a plane secondary deposited the mo / si multilayer on the fused quartz substrates . the reflectivity peak and the reflectivity uniformity of the multilayer mirrors are respectively 25 % and around + 2 . 5 % at 17 . 1nm
望远镜主镜为球面，次镜为平面，所用反射镜为在熔石英基底上镀制mo si多层膜的euv波段反射镜，在17 . 1nm的反射率25 ，反射率的均匀性2 . 5 。 - In this paper , we mainly discuss multilayer mirrors for x - ray solar telescope operating at 17 . 1nm wavelength . the diameter of primary mirror for telescope is 130 millimeters and secondary mirror is 66mm . especially , we will engage in controllation of uniformity of period thickness
本文主要针对工作波长为17 . 1nm的x射线空间望远镜中的主镜与次镜的膜厚分布均匀性进行控制，其中主镜直径为130mm ，曲率半径为7 . 5m 。 - This paper is a part of the project : research of manufacturing technology for unfocused aspherical surface system of large relative aperture , sponsored by national high technology 863 - 802 . the purpose of this paper is deeply research the testing methods of primary and second mirror for unfocused aspherical surface , and to present the testing methods of primary mirror of the large relative aperture and transmission and reflected second mirror . the beam path diagrams and the relative design results are given in this paper
本文是国家高技术项目863 - 802的子课题“大相对孔径无焦非球面系统制造技术研究”的一部分，其目的是对大相对孔径无焦非球面系统的主镜和次镜检验方法进行深入研究，提出大相对孔径主镜和透射式及反射式次镜检验方法，并给出检验方案和相关的设计结果。
