attenuation range meaning in Chinese
衰减范围
Examples
- Put new omnis as blue skylight outside every opening and adjust the far attenuation ranges to fit in the opening area
在每一个开口外放置一个新的泛光灯来作为蓝色的天光，调节它们的远端衰减范围以适合开口的大小。 - The laboratory offers calibration service for coaxial fixed and step attenuators . the frequency range covers 300 khz to 18 ghz and attenuation range of 0 to 70 db
本所可为同轴的固定及阶调衰减器提供校正服务。频段由300khz至18ghz ；衰减幅度由0至70db 。 - Besides this , a bypass multi - mode waveguide were used to improve attenuation efficiency and reduce power consumption . based on buried channel structure , the simulation software beamprop ? produced by rsoft corp shows some better results than the original device : attenuation range over 20 higher , insertion loss merely 1db higher and the calculated power consumption is only 25mw
加入的旁路吸收波导和多模区间距为零时最大衰减对应的温度为60 ，衰减增加了20db以上，功耗也增加了1倍，插入损耗比间距为1 ， 2 m时增加约0 . 4db ，比没有旁路波导时插入损耗增加了约ldb 。 - Electro - optical curves for lc cells have been analyzed and it has been shown mat a large attenuation range and a shallow attenuation slope can be achieved simultaneously for a variable optical attenuator based on a parallel - aligned lc cell with an appropriate surface anchoring strength . as compared with the existing liquid crystal - based voa structure ( using two cascaded lc cells with a particular material ) , the present structure is simple and has no special requirement for the lc materials
提出了基于弱锚定平行排列液晶盒的可变光衰减器(衰减范围大、衰减曲线下降平缓以保证调节精度) ，与己有液晶型可变光衰减器结构(选用特定液晶材料、两个液晶盒级联结构)相比较，本论文提出的基于弱锚定平行排列液晶盒的可变光衰减器结构简单，同时对于液晶材料无特殊要求。
