摘要
水氡观测是全国大多数地震台地震前兆观测的主要手段之一,定期用固体标准源对测氡仪器进行标定是水氡观测工作的重要组成部分。2010年汕头地震台长期使用的固体标准源出现问题无法使用,经过学科组改造后,汕头台于2012年2月开始使用改造后的固体标准源对测氡仪器进行试标定,并对标定环节进行完善改进,使标定过程更加合理,操作更简单,标定结果有较高的准确度和精密度,对今后水氡仪器的标定及水氡观测工作将起到积极作用。
Water radon observation is one of the main methods of the seismic precursor observation in most seismic stations in China. Calibrating radon instrumen the solid standard source is an important component of water radon obse t regularly by the use of rvation. In 2010, there were some problems in the long-term used solid standard source in Shantou seismic stations, and it could not be used. After the reconstruction of the solid standard source by the discipline group, the staffs began to use the reconstructed solid standard source in the tentative calibration of the radon instrument and to improve and perfect the calibration process in February, 2012. It makes the calibration process more reasonable and be easy to operate, which achieves a higher degree of accuracy and precision, and will play a positive role in the calibration of radon instrument and the observation of water radon in the future.
