| 摘 要： | 根据天水地震台ＳＫ地震仪近年来记录的３３８个震例的资料，用最小二乘法求出最大振幅面波与初至波至时差同震中距的关系式，并与Ｊ－Ｂ表进行了对比，结果表明，用Ｊ－Ｂ表计算出的震中距与实际震中距的偏差较大，用本给出的关系式和走时表估算震中距可以缩小误差，提高定位精度。

| Abstract: | According to records of 338 earthquakes in recent years by SK seismograph of Tianshui seismic station,a formula of relationship between travel time difference of maximum surface wave from primary wave and epicentral distance is given by least squares method.It is discovered there is much difference between epicentral distance calculated by using the J B travel time table and that of practical observation, the difference is small by using the formula and travel time table of this paper by comparison. |
