摘　　要：新疆阿克苏ATG-6118H痕量氢分析仪自观测以来,在距离测点300 km范围内共发生7次5级以上地震,其中4次震前存在较为显著的短期异常。震前异常特征明显,主要表现为氢气浓度值的快速上升和幅值波动变化。Since the observation of Aksu atg-6118h hydrogen analyzer,six earthquakes with magnitude above 7 have occurred within 300 kms from the measuring point,and 4 of them had significant short-term anomalies before the earthquakes.The abnormal characteristics are mainly manifested in the rapid rise and amplitude fluctuation of hydrogen concentration values,and the change of earthquake in return after the concentration values reaches a high level.
