| 摘 要： | 本文将ＢＰ神经网络用于地震中短期预报。作者把一些常用的地震学指标作为神经网络的输入，而将ＢＰ神经网络的输出作为表征地震活动平静的特征参数Ｗｑ，井将其用于华北地区进行空间扫描，结果表明中强地震前１年左右或稍长时间，未来震中周围一般都开始出现Ｗｑ值的中短期异常区，证明本方法具有限好的中短期预报效果。

| Abstract: | BP neural networks is used for the mid\|and short\|term earthquake prediction in this paper.Some prediction parameters of seismology are the input units of neural networks.And the output units of neural networks is called as the character parameter W q described quiescence of seismicity.It is used to scan in North China.The result shows that the mid\|and short\|term anomaly zone of W q \|value usually appeared obviously around the future epicenter before earthquake about one year or longer with good prediction ability. |
