摘　　要：洱源地震前两个月,滇西地震预报实验场3个汞观测点均出现短临异常,有一定的准同步性。但3个测点变化在异常形态、异常变化时间上随震中距不同呈现出各自的变化特征,这样的特征对于提高未来地震震中预报精度、实现具有防震减灾实效的短临预报具有重要意义。stations pending in the anoma these mercury Two months Western Yun lies, and the observations before the Eryuan M5.5 earthquake, mercury observations at there was a synchronous anomalies from three observations. But had their own abnormal form and duration in variation character istics with the change of epicenter distance, it would have important significance by studying these short-term and impending characteristics to improve the accuracy of future earthquake location and achieve earthquake mitigation effectiveness.
