| 摘 要： | 以宁波地震台ＤＤ－１短周期仪器记录到的震中距４００ｋｍ左右的地震为例，讨论了该范围近震的震相分析问题。认为在地壳平均厚度约３０ｋｍ的地区的台站，当震中距在４００ｋｍ左右时Ｐ与Ｐｎ、与Ｌｇ差不多同时到达，使震相分析复杂化。指出可以用分析体波或面波的方法来加以确定地震的各项参数。

| Abstract: | As examples of the earthquakes recorded by the DD-1 short-periodsei smograph inNingbo Station with the epicenter distance of about 400 km,the author discussed theproblems of phase analysis of near-earthquakes with in the range mentioned above. Theresults show that when the epicenter distance is about 400 km and the station is in theregion with an average crustal thickness of about 30 km, the author also pointed out thatthe method of analyzing the body wave or the surface wave can be used to determine theearthquake para meters. |
