【摘要】 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。更多还原

【Abstract】 We have compared the data of geomagnetic digital observation with the data of analog observation in detail,and described the feature of digital and analog observation system.We have also discussed the 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 quality of terrestrial magnetism.更多还原
