摘　　要：针对历史震例中原始前兆数据缺失的情况,本文介绍了一种基于Matlab的时间序列曲线快速矢量化程序。经检验,该程序能够快速将历史震例中的前兆曲线矢量化并提取数据。所提取的数据与原始数据在曲线形态和细节方面均高度相似,可以在震例再研究中替代原始数据。Aiming at the original data missing problem in earthquake case study, a new program based on MATLAB is present in this paper which can pick up the original observation data from the related picture rapidly. The test result showed that the program can pick up the original data from the related picture of earthquake precursor in historical earthquake case rapidly. The picked data are highly similar to the original data in curve shape and many details that can be used to replace the original data in earthquake case study, especially in the absence of original data.
