| 摘 要： | 从快速识别事件性质的要求出发,分析了天然地震和人工爆破的发震时间,P波初动方向,P波、S波振幅比值,P波、S波最大振幅与尾波持续时间比值等判据,得到P波初动方向和P最大振幅与S最大振幅比值是识别爆破和地震的两个有效判据,为研制“识别天然地震和人工爆破的分类决策支持系统”提供了应用依据.

| Abstract: | For the request of rapid identification of earthquake and explosion, we analyzed the origin time of earthquake and explosion, first motion of P wave, P, S amplitude ratios,P, S maxi- mum amplitude and duration ratios, and found that the direction of first motion of P wave and P, S maximum amplitude ratio are two effective criterions for identifying earthquakes and explosions. The result provides the application basis for ＂The Decision-making System of Identifying Earthquakes and Explosions＂. |
