It studies the verticaluniformity of single mode fiber attenuation through measurement and gives its evaluation on the uniformity of present single mode fibers.
通过测试研究了单模光纤衰减的纵向均匀性,并对目前单模光纤衰减的纵向均匀性作出了评价。
2
Air flow Horizontal or vertical air flow, depending on the application and uniformity requirements.
空气流动水平或垂直空气流动,这取决于应用和均匀度要求。
3
The results of measurement show that the cooling rate in vertical ventilation is quicker than lateral ventilation and the cooling uniformity is better too.
