【摘要】 利用青海台网记录清晰的P波震相资料,根据单层地壳模型地震走时方程,计算了P波速度和震源深度,得到直达波速度正态分布置信区间为5.96~6.09 km/s,首波波速度置信区间为7.69~8.06 km/s,震源深度置信区间为5.6~5.8 km。更多还原

【Abstract】 Using data of clear P-wave phase recorded by Qinghai Seismic Network,based on the seismic travel time equation of the single-layer crustal model,we calculated the P-wave velocity and focal depth.The results showthat at a 95% confidence level,the confidence interval in normal distribution of the direct wave velocity is 5.96~ 6.09 km / s,that of the head wave velocity is 7.69 ~ 8.06 km / s,and that of the focal depth is 5.6 ~ 5.8 km.更多还原
