在前苏联科学院大地物理研究所攻读学位研究生期间,曾涉足了地球物理学探测中三大难题,即:地震多次波、小幅度断层的分辨和绕射波场动力学,在中、外导师的悉心指导下,对这三个难题进行了研究和探索,并取得了可喜成效.此间发表学术论文(SCI期刊检索)10篇,并通过在全苏公开答辩取得了物理—数学副博士学位.然而这三个课题至今仍然是困绕着复杂波场分析和震相识别的难题,尚必须继续深入研究和深化认识. During the postgraduate studies at the Institute of Geophysics of the former Soviet Academy of Sciences, three major problems in geophysical exploration have been covered, namely the resolution of multiple and minor faults in the earthquakes and the dynamics of the diffraction wave fields. Among the Chinese and foreign tutors Under the guidance and guidance of these three difficult problems, and achieved gratifying results, published 10 academic papers (SCI Journal Search), and obtained a Ph.D. However, these three issues are still the difficult problem of complicated wavefield analysis and phase identification, so we must continue to study and deepen our understanding.
