摘要： 用斯托克斯理论和曲线积分,推导了在漫散发射和反射假设下,均匀和非均匀带锥口圆柱内锥腔的逐点有效发射率分布和积分腔发射率的计算方法和公式。其结果己用于点源黑体的腔型选择和有效发射率的计算。

Abstract: A mathematical model is presented for the local hemisphericaleffective emissivities of isothermal and non-isothermal cylindro-inner-coneswith a cone opening by application of the stokes theorem and contour inte-gration on the assumption that the emission and reflection are diffusive.Aprecise calculation is made for a blackbody.
