This paper explored the theory and technology of the extinction tomography , and it ' s applications in the measurement of gas - particle two - phase flow 本文探索消光层析成像的原理、相关技术及其在气体-颗粒流检测中的应用。
Firstly , the current status of particle extinction study is reviewed , and the methods for computing the particle extinction characters are compared 文章首先回顾了微粒消光研究的发展历程，接着对目前微粒消光的各种计算方法进行评价和比较。
The extinction coefficient of the thinner plct ( x ) films is relative big . on the other hand , the extinction coefficient of the thicker of plct ( x ) films is relative small 很薄的plct ）薄膜的消光系数较大，较厚的plct （ ）薄膜的消光系数较小。
Because of their fine extinction ratio and high anti - light - damage threshold value , laser - polarizing prisms are popular among workers in science and technology field 激光偏光棱镜，以其优良的消光比性能和高抗光损伤阈值性能，倍受科技工作者欢迎。
The specifications of the intensity modulator at 1 . 3 m involved with extinction ratio better than 25 db , and low drive voltage , and wide operation band width and so on 该强度调制器工作于1 . 3 m ,具有大于25db的消光比、低驱动电压、宽工作带宽的特点。
