摘　　要：介绍了张家口地震台的基本现状及形变数字化仪器的改造情况。从长期趋势、短期趋势和固体潮形态变化等方面,对地形变模拟观测和数字化观测资料进行了对比,对资料的连续性、稳定性、一致性和固体潮观测精度进行了分析,得出数字化资料总体评价。并针对数字化观测存在的问题提出了具体建议。We have introduced the Zhangjiakou Seismic Stationts status and the alteration of the digital instruments. The digital observational data of crustal strain are compared with analog data in permanent trend, short-term trend and the change of solid tide modality. We also analyzed the digital and analog data in the field of continuity, stabilization and the precision of the solid tide observation and gained the estimate of the digital data. We have given the material suggestion about the problem of the digital observation.
