absorption coefficient

英 美
  • 吸收系数
  • absorption n.吸收,吸收作用;全神贯注,专心致志;合并;同化
  • coefficient n.系数
Noun:
  1. a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber;

    "absorptance equals 1 minus transmittance"

    1. The absorption coefficient is often strongly wavelength-dependent.
      吸收系数往往与波长密切相关。
    2. Therefore, at sufficiently high energies the absorption coefficient begins to increase after passing through a minimum.
      因此,在足够高的能量下,吸收系数便由最小值开始增加。
