摘　　要：为验证地市级移动校准系统中雨量项目测量量值的一致程度和计量标准的可靠程度,甘肃省气象计量检定站组织甘肃省地市级移动校准系统开展了雨量要素的量值比对工作。首先确定雨量对比方式、比对样品,选择雨量和降水强度作为校准点,分析此次比对中雨量传感器的稳定性、判别比对结果异常数据、评定测量不确定度,最后计算归一化偏差进行评定,得出评定结果。比对工作较为客观地反映了各市州移动校准系统的校准能力、校准人员水平以及标准设备的现状,有效地识别了各参比单位存在的问题,为进一步提升现场校准能力提供可靠依据。In order to verify the consistency degree of rainfall measurement values in mobile calibration system of prefecture level as well as the reliability degree of metering standard,Gansu meteorological metering and verification station organizes mobile calibration systems of prefecture level to carry out the comparison of measurement values of rainfall factors.Firstly,determine the method for rainfall comparison and the samples to be compared.Then,select rainfall and rainfall intensity as the calibration point,analyze the stability of rainfall sensor in this comparison,judge the data found in comparison results,and assess the uncertainty degree of measurement.Finally,calculate normalized deviation for evaluation and obtain evaluation results.The comparison work conducted reflects more objectively the calibration capacity of mobile calibration systems of all cities,the competence of calibration personnel and the current status of calibration equipment,effectively identifies the problems present in all units compared and provides reliable basis for further promotion of site calibration capacity.
