量块比较测量温度的量化及研讨

Research on third class measuring block check temperature measuring of quantization

JJG146-2003《国家量块检定规程》不仅就量块测量温度对20℃的偏差而引入的不确定度做出了不超过被测量块长度测量总不确定35%的要求,同时还在规程的附录中对量块长度测量温度进行了列表量化。本文从三等量块长度测量不确定度分析入手,对三等量块长度比较测量的温度进行分析、量化和讨论,以期对新规程的实施有所帮助。

The JJG146-2003《The check Regulations of National Measuring Block》,not only putting forward not exceeding the requirement of 35 percent of the general degree of uncertainty of length measure of measured block, which induced by degree of uncertainty of the wrap of measuring block of 20℃ measure temperature, but also list quantifies the length of measure block measure temperature in the attachment of regulations.Based on analysis of the uncertainty degree of third class measuring block, we analyze, quantify the temperature of the compared measure of the length of third class measuring.In order to improve the use of the new regulations.
