| 摘 要： | 本文选取湟源台５７３型地震仪在１９９０—１９９１年间记录的４９个共和地震和记录到ＰＮ震相的２５个地震资料，通过计算，得到共和——湟源之间直达波的平均传播速度为；Ｖ（ｐｇ）＝６．７６ｋｍ／ｓ、Ｖ（ｓｇ）＝３．８４ｋｍ／ｓ，湟源地区的地壳厚度为６１ｋｍ。

| Abstract: | The paper chooses 49 of earthquakes Gonghe seismic sequence recorded by 573 seismograph from 1990 to 1991 and 25 seismic data which were recorded PN seismic phase. By calculated,average velocity of direct wave between Gonghe and Huangyuan is;V(pg)= 6. 76km/s,V(sg)= 3.84km/s,the crustal thickness in Huangyuan area is 61km. |
