一、引言利用固相锑和液相锑之间的相平衡而实现的黑体辐射,可作为校准辐射温度计用的红外辐射标准。为此目的,试制了两种锑点黑体—精密型黑体和实用型黑体。前者用作基础标准,后者用作简单的实用标准。这两种黑体由高纯石墨和纯度超过99.999%的锑制成。 I. INTRODUCTION The blackbody radiation achieved by the phase equilibrium between solid-phase antimony and liquid antimony can be used as a standard for infrared radiation used to calibrate a radiation thermometer. For this purpose, two antimony black spots were trial-made - precision black and practical black. The former is used as the basic standard, the latter is used as a simple practical standard. Both black bodies are made of high purity graphite and antimony with a purity of over 99.999%.
