Agglomerates of delusterant particles located near the surface of synthetic fibers cause asperities . 消光剂颗粒集结在合成纤维表面附近，导致表面粗糙。
For example, based on the weight of the fiber, the inclusion of 2% delustesant would produce a dull fiber . 例如，如按纤维重量加入2消光剂，可以生产无光纤维。
The molecular extinction coefficient is equal to the ratio of the log of the intensity of the incident and emergent light . 分子的消光系数等于入射光和透射光强度对数的比。
Data on the molecular extinction coefficients of a number of compounds of this type are now available in the literature . 文献中已发表了一些这类化合物的分子消光系数的数据。
The presence of stray light is indicated by the absence of complete extinction when the phase difference is such that this should be achieved . 若位差达到应当消光的程度，却未能完全消光即表示有杂散光存在。
Test method for extinction ratio of nd : yag laser rods 掺钕钇铝石榴石激光棒消光比的测量方法
Below an extinction coefficient of 0 . 005 m 消光系数每米0 . 005以下
