From two years seismic data continuously recorded by stations directly set up from Fuyun to Kuerle, P_arrival times were picked and image of crust and upper mantle structure was given with the technique of seismic tomography.
利用在2002~2004年新疆天山地区富蕴—库尔勒布设的流动地震台,经过连续两年的观测所采集的数据,挑选远震P波到时数据,进行了地震层析反演处理,获得此剖面地震层析图像推断地壳上地幔的速度结构。
The results show that the crust and upper mantle structures present obvious lateral and vertical inhomogeneity.
利用渤海湾及其邻区的10多条地震测深剖面段观测资料,对部分剖面进行二维射线追踪、走时拟合及合成地震图计算,获得了本区地壳上地幔速度结构。
The three dimensional S wave velocity structure of the crust and upper mantle of Chinese Mainland and its neighboring region is obtained by genetic algorithm of surface wave tomography, with smoothness constraint, based on 25 wave group velocities from 10 to 92 s, measured from long period Rayleigh waves recorded by 11 stations of CDSN and 12 digital seismometers surrounding China.
利用中国数字化地震台网 (CDSN) 1 1个台站和 IRIS在中国周边的 1 2个数字地震台站的长周期瑞利面波资料 ,根据面波群速度层析成像方法反演得到的 1 0～ 92 s周期范围内的2 5个中心周期的群速度分布资料 ,用光滑约束的遗传算法反演得到了中国大陆及其邻域的地壳上地幔横波三维速度结构 ;给出了沿北纬 30°、 38°两条东西向剖面和沿东径 90°、 1 2 0°两条南北向剖面的地壳上地幔横波速度结构 ,并在 4个不同深度的水平切片上展示了中国大陆及邻域的横波速度分布图
