摘　　要：1997年5月25日张家口Ms4．2地震是1997年上半年首都圈地区发生的显著地震，虽然该地震震级不高，但地下流体的短临异常十分显著。作者主要介绍了该地震前地下流体短临异常的特征及由此得到的科学启示。Zhangjiakou earthquake occurred on May 25, 1997, is a remarkable one in the capital area during the first half of 1997. Although the magnitude is not too large, the short-term and imminent earthquake anomalies of ground fluids are quite remarkable. A prediction is successfully made before the earthquake. In this paper, some characteristics of short-term and imminent anomalies of ground fluids and some scientific enlightenment drown from the practice of prediction are presented.
