| 摘 要： | 黄壁庄地磁台总强度Ｆ和垂直强度Ｚ的观测值，从１９９１年４月开始出现了持续１４个月以上的异常变化。同红山台相比，最大下降幅度分别为１０和１２ｎＴ。在１９９２年度会商会上，这个异常被列为强震背景异常，引起了有关地震部门的关注。现经深入细致的调查和测试，证明这个异常变化是距台站１００多米处建筑群的施工所造成的，绝非地震前兆异常。

| Abstract: | The observational values of the geomagnetic total intensity F and vertical intensity Z at the Huangbizhuang geomagnetic station showed a continuous anomoty for 14 months since April 1991. Comparing this variation to those of the Hongshan station, the maximum decending amplitude reached to 10nt and 12nt.respectively. During the Conference on Seismic Situation of 1992, this anomaly was considered as a variation with strong seismic background, and has drawn great attention. However, through deep and further survey and measurement, it has proved that this anomaly variation was due to the constructing ofbuildings about 100m away from the station, rather than an earthquake precursory anomaly. |
