这项研究是为了继续分析全球地震数据集，以解决地球深部结构的细节。这些研究包括利用宽带不连续反射来检测过渡带速度不连续的地形细节、亮度、强度和清晰度；利用短周期数据叠加来成像PKP和PKKP前体并约束小尺度地幔非均质性和核幔边界地形；全球事件检测和定位实验；以及建立包含不连续地形的三维地幔结构统一模型。＊＊＊
英文摘要
9614350 Shearer This research is to continue analyses of global seismic data sets to resolve details of deep Earth structure. These studies include the use of broadband discontinuity reflections to examine details of the topography, brightness, strength and sharpness of the transition zone velocity discontinuities, stacking of short-period data to image PKP and PKKP precursors and constrain small-scale mantle heterogeneity and core-mantle boundary topography, experiments in global event detection and location, and development of unified models of 3D mantle structure which include discontinuity topography. ***
