| 摘 要： | 本文利用中国大陆区共8个台站所观测到地震事件的S波数据，采用相关分析的手段以 观测数据重建的技术，进行了S波分裂参数－快慢波延迟时间与快波偏振方向的计算，并分析了S波分裂参数与中国陆区上地幔物质运动的相互关系，研究了结果表明，兰州台下的S波分裂时差最小，北京台下的最大，中国东部地区上地幔运动方向以西北向为主，西部地区以北偏西为优势。

| Abstract: | We applied the methods of correlation and reconstruction to the S wave data observed at 8 stations in China mainland and calculated the delay time and fast polarization of the S wave splitting. The relationship between the splitting parameters and the substance movement in upper mantle of China mainland has been analyzed. The results show that, the smallest delay time of S wave splitting occurs at the station of LZH (Lanzhou), and the biggest occurs at the station of BJI (Beijing); The movement of upper mantle in Eastern China is mainly north westward, and westward from north in Western China. |
