| 摘 要： | 利用多台资料对比震相识别方法，采用台网中心对地震较精确的定位结果，对南北地震带强化观测台网中心所记录到的地方震、近震、远震分别进行分析。结果表明，随着不同构造区域介质的差异性，地震波传播路径不同，导致各地区所记录到的地震震相特征不同。通过对不同区域地震震相特征的进一步对比分析，找出各区域震相特征的差异性和规律性，为以后台网中对震相识别和精确定位都有一定意义。

| Abstract: | The different phases recorded by ground motion army in north - south seismic belt are analyzed by the identification of multi - station data and the location results. It is shown that the phases are different because of different media in different tectonic regions and different propagation paths of waves. The characteristics of phases in different structure regions are analyzed in order to find their differences and regularity and to identify the phases easily and locate accurately in the array. |
