average transmittance

基本解釋

The average transmittance of thin film in visible region was above 80%.
薄膜可見(jiàn)光透過(guò)率平均可達(dá)80%以上，在紫外光區(qū)有較高的吸收性；
The diurnal variation of average PAR transmittance was greater at noon than in the morning and afternoon.
平均PAR透光率日變化表現(xiàn)為早晚較低，中午較高；
The average transmittance of the coatings in visible light spectrum is up to 75%, and 73% in infrared region, which can provide effective insulation for heat radiation.
光譜分析證實(shí)其在可見(jiàn)光區(qū)平均透過(guò)率可達(dá)75 % ，在紅外區(qū)阻隔率達(dá)到73% ，能對(duì)熱輻射起到有效的阻隔作用。
