reflectivity and transmissivity meaning in English

反射率和透射率

Absorptivity, reflectivity and transmissivity depend upon the wave length of the radiant energy striking the surface and also upon the temperature of the surface .
吸收率，反射率和透射率取决于打在物体表面上的辐射能的波长，也和物体表面的温度有关。
Abstract : the optical admittance of a single - layer film is derived from the characteristic matrix of the film pile . based on the single - layer , recurring layer by layer , supercomposing one by one , deriving the equivalent admittance of the film pile and calculating the reflect coefficient of the amplitude , the reflectivity and transmissivity of hte whole film system is derived at last
