摘　　要：四支铑铁电阻温度计(RIRT)在0.6～27K范围,做了多点比对,按ITS-90示值的偏差在2mK之内。The intercomparison between four rhodium-iron resistance thermometers (RIRT) maintained in the Gryogenic Laboratory have been made. The RIRT 229843, one of the four, was compared with the standard thermometers of the National Metrology Laboratories of the Australia and Nether lands in 1991 and 1992 respectively. The results from these intercomparisons show the uncertainties of our four RIRTs against to the ITS-90 are less than 2mK in the temperature range from 0.6K to 27.1K.
