一、引言必须知道辐射表面发射率的工作的两个最重要领域涉及辐射传热和温度测量。但本文仅与后者有关,并着重讨论使用高温计测温的方法,这种方法能防止用辐射法测温过程中存在的一些问题。在接近黑体状态的表面上,很少进行高温测量,因此在大多数情况下,必须知道辐射表面的发射率,才能通过辐亮度的测量计算表面温 I. INTRODUCTION The two most important areas of work that must know the emissivity of radiated surfaces involve radiative heat transfer and temperature measurements. However, this article only relates to the latter, and focuses on the use of pyrometer temperature measurement method, this method can prevent some of the problems with the radiation method temperature measurement process. On surfaces close to the blackbody, high temperature measurements are seldom performed, so in most cases it is necessary to know the emissivity of the radiation surface in order to calculate the surface temperature by radiance measurement
