| 摘 要： | 对整个福建省的钻孔体应变仪器运行状况进行了综合评价,并对4个台站的观测资料质量进行了分析,用M2波潮汐因子及其相对中误差等来衡量其总体精度和稳定性,还分析了钻孔应变观测的干扰机理和特征,希望能够正确地认识以及排除观测资料中的非异常信息,提高观测精度,为地震分析预报提供可靠的前兆资料。 |

| Abstract: | In this paper,the running state of the instrument system of digital borehole body strain in Fujian province is evaluated and the observation data quality of four digital stations is also analyzed.Here we use tidal factor and relative errors to measure the total precision and stability of the observation data.The analysis of the interference mechanism and the characteristics of borehole body strain observation have also been done.We hope that it would become easier to identify and eliminate the non-abnormal information in the data,to improve the observation precision,and then to supply more reliable auspice information for earthquake analysis and prediction by means of our efforts. |
| Keywords: | Tidal factor digital borehole body strain precision and stability interference analysis |
