经典的短波高温修正模型不适用于中长波红外温度计的发射率修正和不确定度评定。采用有效亮度温度概念，得到了对于温度范围和测温波长具有广泛适用性的发射率影响模型以及具有简明物理含义的微差近似形式，包含了经典亮度温度理论中的发射率影响修正和环境辐射误差修正。定量分析了经典的短波高温修正模型的误差。针对黑体辐射源的不同溯源方法，讨论了辐射温度计校准中的发射率影响修正方法，并给出修正实例。所用方法可用于辐射测温应用、辐射温度计校准和黑体辐射源校准中的发射率和环境影响修正以及辐射源发射率不确定度对校准结果不确定度贡献的计算。

The errOr using the cIassicaI cOrrectiOn mOdeI is discussed under the middIe and IOw temperature measurements. The emissivity cOrrectiOn methOds are described under different bIackbOdy radiatOr traceabIe apprOaches in radiatiOn thermOmeter caIibratiOn,and an exampIe is given. The methOd discussed is suitabIe fOr the emissivity and refIected ambient radiatiOn cOrrectiOns and assOciated uncertainties caIcuIatiOns in the appIicatiOns and caIibratiOns Of radiatiOn thermOmeters and bIackbOdy radiatOrs.
