摘要
加卸载响应比理论具有雄厚的物理基础，把它引用到以磁报震中，即有利于以磁报震工作的发展，也是对加卸载响应比理论应用的延拓。我们取太阳日照为加载，地磁垂直分量之为响应，研究了利用北京台１９７Ｏ──１９８６年资料所计算出的响应比与１９７６年唐山大地震的关系。结果发现１９７６年地震前约半年时间内的响应比明显高出其他各年。通过地质前后共１７年的资料分析，确认这正是地震前兆。
The theory of load-unload response ratio is based on physics. The application of itin the prediction of earthquake by geomagnetism can not only benefit the development ofthe prediction of earthquake by geomagnetism, but also is the development of the appli-cation of this theory.The sunshine is taken as the load,the geomagnetic vertical compo-nent,Z, as the response here. Data of Beijing Observatory in the period of l970-1986are analyzed.The response ratios are calculated.The relationship between the ratio timeseries and Tangshang earthquake in l976 is investigated.The results show that there isa significant precursor in the first half year of l976.And the anomaly exists only in thatperiod.This results encourage us to develop the research.
