摘　　要：介绍了易县地震台的基本现状及形变数字化仪器改造情况,并从长期趋势、短期趋势和固体潮形态变化等方面对易县地震台形变模拟观测和数字化观测资料进行了对比。对数模两种观测资料的连续性、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,并对数字化资料存在的问题提出具体建议。The actuality of Yixian Seismostation and its digitalized reconstruction for crustal deformation observation are introduced. The digital and analogue data of crustal deformation are compared in the field of long term and short term tendency, earth tide, and so on. Through comparison on the continuity, stability, consistency and tidal precision of the two kind data, a general evaluation on digital data is given, and some proposals are also presented.
