摘　　要：热电阻是由一个或多个感温电阻元件组成的,基于电阻值随温度变化而变化这一原理进行测量。依据JJG 229-2010《工业铂、铜热电阻检定规程》,文章主要是对B级工业铂热电阻测量结果的不确定度进行了详细评定,讨论了热电阻在0℃、100℃测量不确定度的主要因素与来源。并且对标准不确定度、合成不确定度、扩展不确定度的评定都进行了阐述。The thermal resistance is made up of one or more temperature sensitive elements.The measuring principle is based on the principle that the resistance value changes with the temperature.According to the JJG229-2010《industrial platinum copper resistance thermal verification regulation》, this paper evaluated the measure uncertainty of industry platinum thermal resistance in B grade,discussed the main influence factor and source of the thermal resistance measurement uncertainty at 0 degrees centigrade and 100 degrees centigrade.And the evaluation of standard uncertainty,uncertainty of synthesis,evaluation of expanded uncertainty were described in this paper.
