摘　　要：1993年10月26日托来6.0级地震发生在甘肃河西前兆台网控制范围之外。本文在研究河西中西部地区前兆台网综合监测能力及总结震例的基础上指出,前兆台项少,持续时间短,空间分散是托来地震前兆异常时空分布的显著特征,并对形成的原因进行了探讨。The Toulai earthquake occurred on Oct. 26, 1993 was beyond the controlling extent of the network of precursory stations in Hexi region. In the paper, based on the study of synthetic monitoring capability and earthquake cases summation, we've found the following fearures: the earthquake duration is short, the observational items are fewer, anomalies are distributed in a large area. Finally, we discussed the cause of those features.
