The molecular extinctioncoefficient 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。

The intensity of forward-scattered light is measured by the forward-scattering visibility sensor, which determines the extinctioncoefficient of the air, then the visibility can be obtained.
前向散射能见度仪测量前向散射光强度，确定大气的消光系数，进而获得大气的能见度值。

The light distribution within the canopy is subject to the leaf area index and the extinctioncoefficient.
