| 摘 要： | 提出了利用RSI的瞬态地壳形变信号探测方法，并将其应用于北美洲卡斯卡迪亚古陆俯冲带区域的部分GPS连续跟踪站的时间序列的瞬态形变探测中。研究结果表明：RSI方法能有效探测各序列中的瞬态形变，且能获得瞬态形变发生的开始时间、结束时间、持续时间和滑移量；与未使用偏移改正的序列相比，使用瞬态偏移改正得到的残差时间序列方差显著减小。

| Abstract: | A transient deformation method based on relative strength index is proposed in this paper. In the case study, RSI is used in the transient deformation detection from the time series of GPS continuous tracking stations located in the Cascadia subduction zone of North America. The results show that the RSI method can effectively detect the transient deformation in each series, and obtain the start time, end time, duration and slippage of the transient deformation. The variance of residual time series with the transient deviation correction are significantly smaller than the ones without the transient deviation correction. |
