beam attenuation

基本解释

Increase of total suspended matter results in decrease of transparency and increase of beam attenuation coefficient.
悬浮物浓度的增加是引起湖水透明度降低和光学衰减系数增大的主要原因。
As a result a marked increase in beam attenuation coefficient occurred, simultaneously with the increase of pigment concentration.
由于浮游植物大量繁殖，光束衰减系数随叶绿素a含量升高而增大。
Thirdly, the fog attenuation for Gauss beam propagation is discussed, and the computational results are compared with those with plane wave incidence.
对高斯波束在雾中的衰减进行了讨论，并将数值计算结果与平面波结果进行了对比。
