摘要：

A method is proposed for determing the total emissivity of a nonblack object in the form of a right circular cylinder. The temperature of the front surfaces of the specimen in a cylindrical vacuum vessel is held constant and a characteristic temperature distribution found for a given emissivity. The temperature depends on the ratio of total emissivity to the thermal conductivity of the material. This relation provides emissivity determinations to within about five percent.
