| 摘 要： | 蒙城地震台地磁偏角日均值自1999年7月起出现了趋势性变化,台站观测人员搜集整理了周边泰安、郑州、佘山、武汉地磁台的三分量数据,应用对比、相关分析等方法,研究了此变化,认为是地磁场的长期变,非地震趋势异常。 |
| 关 键 词： | 地磁偏角 日均值 趋势性变化 地磁场 |

| Abstract: | Since July 1999, the Geomagnetism declination angle daily mean has been emerged trend variation on Mengcheng Station. The observers of the station collected and processed the data of the tri-component of the circumjacent geomagnetic stations of Tai an, Zhengzhou, Sheshan and Wuhan; applying the methods of comparable analysis, relative direction analysis, etc to analyze and study this change. It is concluded that the variation is not the earthquake trend anomaly, but a long period variation of geomagnetic field. |
| Keywords: | geomagnetism declination angle daily mean trend variation geomagnetic field |
