地震氡观测仪检测平台的设计初探
A Preliminary Study of the Design of Emanometer Measurement Platform in Earthquake Monitoring
【摘要】 地震氡观测仪检测平台是"十三五"地震地下流体学科观测仪器检测平台的重要组成部分,是地震流体学科第一个检测平台。本文对其设计理念、建设内容进行介绍。平台校准单元设计符合《测氡仪检定规程JJG825-2013》技术要求,氡浓度的测量范围达到800~15 000Bq/m3,扩展不确定度达到8%(k=2),72h稳定性优于5%,检测单元设计将承担新研发仪器和复检仪器的性能检测与质量评估工作。整个平台建成后,将满足全国正在运行的地震氡观测台网300多项氡观测仪的校准需求,为每年30~50套氡观测仪提供更新或新建氡观测台站的仪器提供性能检测服务,保证地震行业氡观测质量。
【Abstract】 The design concept and construction content of a seismic emanometer measurement platform,the first testing platform for a seismological fluid subject,are introduced in the paper.The design of the platform calibration unit agrees with the technical requirements of JJG825-2013 Verification Regulation of the Radon Measuring Instruments.The measurement range of radon concentration is 800~15 000Bq/m3,and the expanded uncertainty reaches 8%(k=2).The detection unit can test the performance and evaluate the quality of the new R & D instruments and the reinspection instruments.When of the whole platform is designed,it will meet the calibration requirements of more than 300 radon observatories in the earthquake radon observation network,and will be used for performance testing in 30~50sets of radon observatories per year to ensure the quality of radon observation in the earthquake industry.
