摘　　要：为研究国产TBL型地球辐射表的各项性能 ,通过与EppleyPIR型地球辐射表的对比测试 ,发现国产仪器除灵敏度略低于EppleyPIR外 ,其它性能并不逊色 ,而且还发现了地球辐射表的一些特性。它们在以前文献中未见报道过 :如由于仪器体内存在温度梯度而引起的仪器体温测不准性和EppleyPIR性能方面的某些不足 ,以及在选用一台地球辐射表作为相对标准时 。The purpose of this paper is to study the main technical properties of homemade model TBL pyrgeometer,test compared with Eppley PIR showed that the main technical properties of TBL pyrgeometer is in good performance.Sensityiity of TBL appears slightly lower than that of PIR.There are some general characteristics of pyrgeometer,which are as follows:pulsation of longwave radiation of the earth;uncertainty of measured body temperature due to the temperature gradient inside the instrument.Some problems concerning selection of pyrgeometer as a relative standard were also discussed in the paper.
