石英滤光片 meaning in English

quartz plate filter

Four - bf is designed to expand tunable region , for further application . and parameters of et with blazing - grating are theoretically ascertained quantitatively
并设计了四元石英滤光片，扩大了调谐范围，为其进一步应用奠定了基础。
On this basis , the ets with three - birefringent filter ( bf ) and two - prism device are finished successfully accompanied with ideal result : the former region is 724 - 781nm ; the latter ' s is 723 797nm , as proved the characteristics in reference that output increases continuously accompanied with enhancement of temperature .
以此理论为基础，在调谐方面，成功地完成了三元双折射石英滤光片调谐实验、双元棱镜调谐实验，取得了较好的结果(前者的调谐范围： 724 ~ - 781nm ，线宽0 . 15nm ；后者调谐范围： 723 - 797nm ) 。
