| Abstract: | The radiation properties of nonisothermal cavity was calculated by Monte-Carlo method.The effective emissivity corrections affected by the temperature distribution along the cavity wall,the spectral effective emissivities and the directional emissivities have been discussed.It can be used as the theoretial calculation basis for the design calculation of blackbody radiation source. |
