摘　　要：选用标准金属量器作为主标准器,采用容积比对的方法对燃油加油机校准结果进行不确定度分析。围绕测量重复性、标准器、被检燃油加油机等不确定度来源进行评定。The standard metal meter and electronic stopwatch are selected as the standard device,and the uncertainty of the indication error of the on-line Flowmeter is analyzed by using the comparison method. The sources of uncertainty such as measurement repeatability,standard instrument and subject table are evaluated.
