【摘要】 利用天水地震台1986～1989年的地震资料及《中国地震台站临时报告》，试算出了通道波πg、Lg1、Lg2及其速度，用最小二乘法初步求得πg、Lg1、Lg2波在本区域的走时关系式，并对πg、Lg1、Lg2波震相在该台的记录特征做了讨论。更多还原

【Abstract】 Using the earthguake data recorded by Tianshui station during 1986～1989 and "Bulletin of Seismological Observation of China",the authors have calculated the waves of Lg1 .Lg2 and their velocity in Tianshui area,and discussed their trave time characteristics in Tianshui station.更多还原
