应用多台和达法测定福建仙游ML4.1地震序列的ML≥1.5地震的波速比，其计算的相关系数较高，测得的波速比值具有较高的可信度。分析ML4.1主震前后的波速比发现，波速比经历了低异常值—回升—相对稳定—下降—主震发生的过程，余震期里出现多次高异常值。

Determined Average Seismic Wave Velocity Ratios in Fujian Xianyou ML4.1 earthquake sequence of ML≥1.5 earthquakes by Using Multi-Station Methods,the high correlation coefficient was calculated, the measured wave velocity ratio value with high reliability.Analysized the before and after ML4.1 main shock wave velocity ratios,drew a conclusion that they experienced low abnormal values—rebound—relatively stable—decrease and the main shock occurred process,aftershock stage appeared multiple times high abnormal values.
