唐山地震后发现的天文时纬残差异常现象一直得到人们的重视。我们为此已进行了十余年的不懈努力,收集了近百个残差异常震例(短期30例,中期70例左右),寻求了地学证据,设计了在地震监测工作中的应用方案,研究了它的产生机理。1985年,我们向国际天文学联合会第19届大会提交的有关报告与建议,引起第19届委员会(地球自转)与会代表的兴趣,为此形成决议并成立专门工作组(见本刊1986年,第9期,25页)。大量历史资料的详细分析与理论计算证明,光学时纬仪器的最大优势是其长期测量精
The anomaly of astronomical latitude and longitude residuals discovered after the Tangshan earthquake has been valued by people. For this reason, we have worked tirelessly for more than ten years and collected nearly one hundred residual earthquake anomalies (30 in the short term and 70 in the mid-term), sought geo-spatial evidence and designed applications for seismic monitoring. The mechanism of its production is studied. In 1985, the relevant reports and suggestions that we submitted to the 19th IAEA General Assembly have aroused the interest of the delegates of the 19th Committee (Earth Rotation), for which we formed a resolution and set up a special working group (see 1986, No. 9, p. 25). Detailed analysis of a large number of historical data and theoretical calculations show that the biggest advantage of optical latitude and longitude instruments is its long-term fine
