摘要：

The infrared emission spectra of LiF single crystals and thin slabs were measured as functions of temperature, emission angle and thickness. The relationship between the normal emissivity and the reflectivity experimentally determined has been discussed in connection with Kirchhoff's law. The frequency and width of the thermal emission due to the virtual modes in LiF slab have been given as functions of temperature and thickness of the slabs. Measurements were performed at temperatures 420°K and 605°K and at emission angles ranging from 0° to 30°. Results of measurements and those of calculations have been discussed on the basis of the virtual mode theory. © 1968, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
