【摘要】 为测试P2000测氡仪工作性能,利用宁波地震台ZK03井原气氡观测系统,将SD-3A型测氡仪排气管接入P2000型测氡仪进气口,2套仪器作串联并行观测。通过对1年观测数据整点值做相关系数分析,发现存在显著相关性。P2000型测氡仪具有自动扣除本底污染的功能,观测值平均仅为SD-3A仪约60%,但能记录到气氡潮汐现象,能真实反映地下流体中气氡的动态变化过程,认为可以在地震流体气氡连续观测中应用,只是收数软件需进一步改进。更多还原

【Abstract】 In order to test the performance of P2000 emanometer, using ZK03 wells gas radon observation system at Ningbo Seismic Station, connected exhaust pipe of the SD-3A radon detector of type exhaust pipe to type P2000 emanometer inlet, the series parallel observation of 2 sets of instruments experiment has carried out. Through the analysis of correlation coefficient on the whole point data of 1 year, it is found that there is significant correlation between data from the two instruments. The P2000 emanometer has the function of automatically deducting ambient pollution. Its observations on average are only about 60% of SD-3A, but can record the gas radon tide phenomenon and can reflect the dynamic change process of underground fluid gas radon. The experiment shows that P2000 emanometer can be used in gas radon continuous observation of earthquake fluid, while the data acquisition software need to be further improved.更多还原
