| 介绍了１种多色温度计实现的方法。目标表面发射率的未知性和多变性是影响辐射温度示值准确性的主要原因。多色温度计是减弱发射率影响获取表面真实温度的手段之一。在综合了大量文献的基础上，文中讨论了多色温度计的原理，分析了几种数据处理的方法，设计和实现了１台四色温度计。 |
| 英文摘要: |
| This paper introduced a realisable method of multiwavelength pyrorneter. The unknown and variety of surface emissivity of an object is the main cause which affects the accuracy of the radiation pyrometer indication. The multiwavelenth pyrometer is one of the effective methods to decrease the effect of the emissivity and acquire the true temperature of the object surface. On the basis of synthesizing many references, the author discussed the theory of multi - wavelength pyrometer in detail, analyzed some algorithms of data processing, and designed and reallsed the fourcolour pyrometer. |
