摘要
文章以表层水温表为研究对象,根据JJG 289—2005表层水温表检定规程的要求,以计量标准器二等标准铂电阻温度计及配套设备制冷恒温槽为基础,详细分析了表层水温表温度测量值的不确定度来源,从而得到表层水温表温度示值误差的扩展不确定度,并给出了减小合成标准不确定度的方法。
According to the requirements of JJG 289—2005 "Surface water thermometer",this study took the surface temperature as the subject investigated.By using the measuring standard device which including the second class standard platinum resistance thermometer and the refrigeration thermostat,the source of uncertainty of surface temperature measurement was analyzed in detail.Thus the expanded uncertainty of surface temperature indication error was obtained,and the method of reducing the combined standard uncertainty was given.
