【摘要】 本文导出了波段光子出射度N_0,λ、波段辐射出射度M_0,λ的解析表达式。并证明了光子相对微分出射度K_⊿N（λ,T）和相对辐射微分出射度K_⊿N（λ,T）的严格关系式。这些表达式对于黑体辐射测量自动化、数值表的精密计算、误差的可靠估计、减少独立黑体辐射函数数目、包含辐射函数的方程的求解、编制精密的有关程序等都是有利的。更多还原

【Abstract】 The analytic expressions of the photon radiant exitance and the radiant e(?)itance are derived. Two exact relations of the photon relative differential radiant exitance are given. All these expressions are useful for the automation of measurement, accurate caloulation of datum table, reliable estimation of the errors, reduction of the number of independent special functions and for solution of some equations containing radiation functions and some relevant programmings in the blackbody radiation.更多还原
