| 摘 要： | 本文对澜沧─耿马大地震前后滇西实验场的重力场时空变化特征进行了初步分析，结果表明，地震之前，滇西实验场的重力变化有一个上升、下降的变化过程，地震发生在重力变化下降时段，震后迅速恢复。

| Abstract: | In this paper, the space-time variation characteristics of gravitational field in WYSES before and after the lancang-Gengma earthquakeis preliminarily analysed. The resuets show that there was a rising-falling course of the gravitational variation in WYSES and the earthquake occurred in the falling phase, and the gravitational variation after the earthquake quickly returned to normal level. It is considered that the characteristics of gravitational variation might be related to the large Lancang-Gengma earthquake. |
