beam attenuation

基本解釋

Increase of total suspended matter results in decrease of transparency and increase of beam attenuation coefficient.
懸浮物濃度的增加是引起湖水透明度降低和光學(xué)衰減系數(shù)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.
由於浮遊植物大量繁殖，光束衰減系數(shù)隨葉綠素a含量陞高而增大。
Thirdly, the fog attenuation for Gauss beam propagation is discussed, and the computational results are compared with those with plane wave incidence.
對高斯波束在霧中的衰減進行了討論，竝將數(shù)值計算結(jié)果與平麪波結(jié)果進行了對比。
