摘要(Abstract):

在通风机性能试验中,压力是主要的测量参数。为了了解通风机测量结果的质量评价,通过不确定度的评定,对压力测量的不同方法进行了分析、比较,并找出了改进测量质量的途径和方法。
Pressure is an important parameter to be measured in fan performance test.In order to assess the quality of fan test results,the uncertainty of pressure measurements by different methods has been evaluated and compared,through which the test quality improvement is also recommended.
