单词	transmittance
释义	transmittance /tranzˈmɪt(ə)ns / /trɑːnzˈmɪt(ə)ns/ /transˈmɪt(ə)ns/ /trɑːnsˈmɪt(ə)ns/ noun Physics The ratio of the light energy falling on a body to that transmitted through it.Designed for spectral analysis of microscopic samples as small as 1 mm, the instrument can measure by transmittance, absorbance, reflectance, fluorescence, and polarization.... The apparatus determines the transmittance of light through the sample leaf at two wavelengths. To compute the transmittance, the direct incident radiation has to be measured in a fixed position, which can be done in a small canopy gap because of the reduced viewing angle of the sensor.
