And the effects of small changes of thin film thickness, incident angle and wavelength on extinctionindex of this polarizer are also studied.
同时研究了薄膜厚度、入射角及波长的微小变化（或误差）对于该偏振器消光率的影响。

The light distribution within the canopy is subject to the leaf area index and the extinction coefficient.
光在冠层内的分布，受叶面积指数和叶片消光系数支配。
