摘要/Abstract

摘要：

主要根据2007年美国地球物理联合会(AGU)秋季会议的资料,简述了地球深部科学研究最近几年来的新进展。主要涉及以下几方面领域:复杂的地球动力学模拟到状态方程理论和实验研究;地幔相变和地震的不连续性到深源地震机制;地核的结构和动力学到地球内部的挥发性物质和熔体等地球深部科学研究。从会议的内容看出有三个亮点是值得我们注意的: (1)学科间的融合是地球深部科学研究的主流方向; (2)国际间的合作是当前地球深部科学研究的一大亮点; (3)高精度的技术(超级计算机(supercomputers)和集群 (clusters) 纵观计算机)是地球深部科学研究的新手段。中国科学家应该关注固体地球科学中这个前缘研究同时共享世界先进科学研究的新成果。

Abstract:

Recent progress in several aspects in the study on the Earths deep interior are discussed, with reference to the international conference on the American Geophysical Union (AGU) Fall Meeting in 2007.The scientific problems involved vary from the comprehensive testable predictions of geodynamic models to the equation of state theories and experiments, from mantle phase transitions and seismic discontinuities to mechanisms of deep earthquakes, from structure and dynamics of Earths core to volatiles and melts in the Earths interiorAll major fields in the study of Earths deep interior are under discussion.The conference suggests that: (1)The merge interdisciplinary is a major trend in the development of the Earths deep interior study; (2)International cooperation becomes a new highlight in the research of the Earths deep interior sciences; (3)Highly precise technique (modern supercomputers and clusters) is a new way of understanding the Earths deep interior sciences; Chinese geoscientists should pay more attention to the frontiers of Earths deep interior sciences, join the noted international conference and share the advanced knowledge.
