佘山地震台地磁模拟、数字观测资料的对比分析

Comparative analysis of the magnetic observed data for the digital and simulated records in Sheshan Seismic Station

对佘山地震台地磁数字化观测资料和模拟观测资料D、H、Z等地磁要素日变形态、日均值、月均值、年均值进行了较详细的分析比较,阐述了数字观测系统与模拟观测系统的特点。探讨了磁场剧烈扰动对数字观测系统和模拟观测系统的影响。对做好地磁数字化观测工作,提高地磁资料的观测质量有一定参考意义。

We have compa servation in detail have also discusse e data of geomagnetic digital observation with the data of analog obdescribed the feature of digital and analog observation system. We influences of disturbance of magnetic field to digital observation system and analog observation system. These works is significance for doing well digital observation and improving the observation qualitv of terrestrial magnetism.
