摘　　要：数字式气压计是测量大气压力的常用仪器。为评价各个实验室间数字式气压计计量校准结果的一致性,由湖北省气象信息与技术保障中心作为主导实验室,组织实施2023年0.1级数字式气压计比对。比对采用花瓣式的比对方式,参比实验室按照比对方案的要求,对传递标准进行比对实验和不确定度评定。主导实验室对比对数据进行汇总分析,采用归一化偏差方法和Z比分数法来评价比对结果。比对的实验数据真实可信,比对结果客观地反映各参比实验室的校准数字式气压计的水平。The digital barometer is a common instrument for measuring atmospheric pressure.In order to evaluate the consistency of the measurement and calibration results of the digital barometers among various laboratories,Hubei Meteorological Information and Technology Support Center organized the 0.1 level digital barometer comparison in 2023 as the pilot laboratory.The petal-type comparison method is adopted for this comparison.The participating laboratories carried out comparison experiment and uncertainty evaluation on the transfer standard according to the requirements of the comparison scheme.The pilot laboratory analyzed the data,and used the normalized deviation method and Z-score method to evaluate the comparison results.The comparison experimental data is true and credible.The comparison results objectively reflect the level of calibration of digital barometer in each participating laboratory.
