摘要
对大气采样器计量标准的测量不确定度来源如计量标准、流量示值误差、流量重复性、温度计示值误差进行了分析和评定,计算得合成标准不确定度和扩展不确定度分别为0.65%和1.30%。对测量不确定度的合理性进行了验证。
The sources of the measurement uncertainty of the measurement standard for the air sampler such as metering standard, flow rate value error, flow rate repeatibility, temperature value error and pressure value error were analyzed and evaluated. The combined standard uncertainty and the expanded uncertainty were 0. 65% and 1. 30% respectively. The rationality of the measurement uncertainty was also validated to be reliable.
