使用内蒙古地震台网记录的内蒙古中西部59个地震,使用单纯型方法和Pn/Pg联合测定深度方法,对震中和震源深度重新测定,提取定位结果的纵波走时数据.使用理论走时公式,将已知变量和未知变量分离建立方程组,使用共轭梯度法,反演得到包含5个参数的两层均匀速度模型.使用Hyposat方法,对比新模型和现有模型的定位残差,新模型残差有所降低,震源深度控制较好.

Using simplex method and Pn/Pg combined method, 59 earthquakes in western and central Inner Mongolia are relocated, and the travel time data is obtained. By variable separation, 1D crust velocity with five parameters is inverted with conjugate gradient technique. Comparing with reference models, the residual error is reduced and depth control is batter.
