摘要：
The infrared radiant characteristics of blackbody are researched and the effective emissivity of blackbody is calculated based on Monte Carlo method. The infrared radiant random model of blackbody is established based on the Monte Carlo method. A large amount of random infrared radiations are sampled and tracked. The approximate value of blackbody effective emissivity can be obtained by counting the radiant properties of blackbody. The results of simulation experiments and theory analysis demonstrate that proposed method can resolve the calculational defect of blackbody radiation by utilizing the integral algorithm, and the computational complexity is reduced effectively due to the new method, which removes the integral algorithm of current Monte Carlo method. The effective emissivity gained by simulation is basal coincident with the actual effective emissivity of blackbody. Theory analysis and simulation experiments show that the new method is reasonable and efficient.
