【摘要】 将磁暴过程作为地球磁场对太阳风的加卸载响应，分析了平谷台１９９５年１月至１９９８年４月期间磁暴场的暴时扰日变化Ｄｓ（Ｚ）的响应比值Ｐ（Ｚ）的变化。发现Ｐ（Ｚ）高值与平谷台５５０ｋｍ，左右范围内ＭＳ≥５０的中强主震有较好的对应。更多还原

【Abstract】 Taking the magnetic storm process as the load unload response of geomagnetic field to the solar wind,the LURR (P(Z)) of the storm disturbed day variation D s(Z) in the magnetic storm field observed at Pinggu Station from Jan.1995 to Apr.1998 was analyzed.The result shows that the emergence of the high values of P(Z) have close relationship with that of moderately strong earthquakes with magnitude M S≥5 0 within 550 km of the station.更多还原
