%X The Sealing Cavity method for determining the emissivity of the target object simplified the measuring and computing process. According to above mentioned method, in this paper, the influence on the accurately measuring result of the undulation of target object emittance and environment emittance have been analyzed. Also, we discuss the effect of wavebands between different infrared radiometers. Through lots of experiments, the optimum contrast temperature difference between hot environment and cool environment is given. Finally, three conclusions are drawn to guide the measurement of emissivity.
