实验证明吸收波段上的油膜透过率随着油膜厚度增加呈指数衰减。
The experimental results demonstrate that the transmissivity of oil-film in the absorption band is exponentially decreased with the increase of the film thickness.
其次，利用TM影像的第四和第三波段计算植被指数，根据植被指数按照转换模型提取植被覆盖度；
Next, vegetation index was calculated which was based on Band 3 and Band 4 of TM image, and degree of vegetation coverage was extracted according to NDVI based on the transformation model;
综合比较所有由红绿蓝光波段各种组合构成的植被指数对LAI的估算能力，认为GNDVI和GBNDVI与LAI有比较好的关系。
The capabilities of these vegetation indices derived from all kinds of combinations of red, green and blue bands to LAI estimation were compared. GNDVI and GBNDVI have the best relation with LAI.
探测器对波段外激光的电压响应随线性工作区间内的波段内激光功率升高而增大；随着波段内激光趋于饱和，对波段外激光的响应电压近似指数级下降。
The voltage response to the out-of-band laser increases with the rise of line-working in-band laser power and decreases rapidly while the in-band laser power approaches to the saturation threshold.
