The main problem in radiation thermometry is how to minimize the measuring error resulting from unknown or variant surface emissivity.
辐射测温的主要问题是解决未知的或变化的表面发射率所引起的误差测量。

Three-wavelength pyrometer can eliminate the effect of emissivity in the radiation temperature measurement, for example, measuring the surface temperature of a polished metal.
三波长辐射温度计能消除发射率对测温的影响，尤其是对抛光表面的测温。

A novel multi-spectral radiation pyrometer that is independent of the emissivity has been developed.
