一、基础本文主要对辐射温度计或辐射高温计的非接触式测温作一介绍。如图1所示,辐射温度计吸收的辐射通量组成部分是: (1)外界辐射体的辐射被被测对象反射的部分,以反射率ξ表示。(2)辐射被被测对象吸收而又发射的部分,以吸收率α表示。(3)辐射透过被测对象的部分,以透射比τ表示。

First, the basic This article mainly radiometric thermometer or radiation pyrometer non-contact temperature measurement for an introduction. Shown in Figure 1, radiation thermometer radiation flux absorbed by the components are: (1) the radiation of the external radiator is reflected by the measured object, with reflectance ξ said. (2) The part of the radiation that is absorbed and emitted by the measured object is expressed by the absorption rate α. (3) Radiation transmitted through the measured part of the object, the transmission ratio τ said.
