摘　　要：叙述了利用固体潮包络法和差分、日均值等方法识别大同—阳高6.1级地震前山东倾斜台网的前兆异常.认为泰安、马陵山自记水管仪和烟台石英摆倾斜仪3台仪器在时间、量级(10^(-7)弧度)和方向上具有一致性并分析了引起该情况的原因.Short-impending anomalies of Shandong tiltal observation network before Datong-Yanggao Ms 6.1 earthquake have been identified using the tidal envelope method, the differential method and the diurnal mean value method. The paper suggests that the anomalies of the water- tubetilt-meters at Taian and Malingshan stations and the quartz pendulum tiltmeter at Yantai station show uniformness on time, magnitude (radian10-7) and direction. The cause of the uniformness has been analyzed.
