摘　　要：应用潮汐偏角法对山东泰安、马陵山、烟台 3个台的石英摆倾斜仪、自记水管倾斜仪资料进行了分析处理 ,结果显示 :泰安、马陵山分点潮汐偏角在华北各次 5.0级以上地震、特别是黄海地震前 1年 7个月至 1个月时段内出现了高值或低值异常 。By means of tidal declination,the tilt data of watertube tiltmeters and quartz pendulum tiltmeters at Taian,Malingshan and Yantai observatories in Shandong Province are analyzed.The results show that the tidal declinations of Taian and Malingshan at equinoctial point reveal a little of anomalous information before the earthquakes (Ms≥5) occured in North China,especialy before the earthquakes in South Yellow sea,it showed higher or lower value of anomaly during the period from 1 year and 7 months to 1 month before the event.The study presents the prospect of the application of tidal declination to mediumshortterm and shortterm earthquake prediction.
