| 摘 要： | 震相识别已经有很多方法，但对于弱震相识别的难题尚未根本解决。本文利用台阵技术能增强地震信号，压低噪声的特点，实现FK扫描技术结合台阵响应进行地震事件扫描，根据其所得的水平视慢度、方位角及其一致性实现震相识别，特别是特殊震相的识别，这些特殊震相的识别为研究地球内部结构提供了可靠的资料和有利的保障。

| Abstract: | There are a lot of methods to identify seismic phases, but the identification of weak phases is not solved ultimately. Taking the advantage that seismic array can enhance seismic signal and reduce noise, combining site response, we realized seismic event scanning with FK technology. According to the horizontal apparent slowness, azimuth and their coherence, we can identify seismic phase, especially special phase. The identification is useful in the research of the earth's inner structure. |
