CONTRASTIVE ANALYSIS TO THE DIGITAL AND ANALOGUE DATA OF CRUSTAL DEFORMATION IN ZHANGJIAKOU SEISMOSTATION

    摘要
  • 摘要: 介绍了张家口地震台的地质构造和形变观测数字化改造情况,对2002年数字化和模拟资料的一致性、观测精度进行对比,分析产生差别的原因,探讨辅助观测和观测值的相关性,得出张家口台的数字化改造是成功的,资料连续率高,质量高,数字化资料完全能替代模拟资料,同时注意数字化观测系统应从数据处理、分析方法及精度评定上逐步完善,才能提取真实的前兆异常,更好地应用于地震预报。

     

    Abstract: the geological structure of Zhangjiakou Seismostation and its digital reconstruction in crustal deformation observation are introduced. The accuracy of the digital and analogue data observed in 2002 is contrasted. The cause of difference and the dependence of observation data with auxiliary observation data are analysed. The results show that the digital data is good in continuity and quality, can replace the analogue data.
