摘要
从计算矿物物理学角度,较好地解释了在1000～2100km深度范围内Rs/p区域地震模型展示的异常行为,揭示了下地幔内不连续界面所处的深度存在横向变化的原因,并指明该界面具有物理界面特征.
Based on the principles of Computational mineral physics,the anomalous phenomena of the seismologically observed Rs/p regional models between 1 000 and 2 100 km depths are adequately explained. The origin of the lateral variations in the depths of the discontinuous interface in lower mantle is revealed,and the interface is shown to be characterized by the features of physical interface.
