| 摘 要： | 国内外有关卫星热红外异常与地震关系的文献已有许多 ,但大部分是探讨或研究震源区地表及上空产生增温异常现象。天线附近背景噪声和强震前后形成的电磁波与卫星数据传输载波产生随机共振 ,造成卫星图像中出现特殊异常现象 ,这种异常与强震具有非常明显的对应关系 ,通过进一步研究 ,可以开拓电磁波随机共振应用的新领域进行短临地震预报。

| Abstract: | There are many papers about the relationship between satellite thermal infrared anomaly and earthquake in the world, but most of them study thermal anomalies of surface and air of focus region We could predict earthquakes not only by temperature anomalies of satellite thermal infrared imageries, but also by special abnormities appearing on satellite thermal infrared imageries The special abnormities are produced by stochastic resonance near antenna between background noise,electromagnetic wave from strong earthquake and carrier wave that transmits satellite data They include black holes and diamonds by disturbance The blackholes are black areas of satellite imagery because the standard location table is disturbed The diamonds are white enclosed diamond line on satellite imagery when isolines of temperature are showed because the standard temperature table of gray rank is disturbed They are not real temperatures of cloud layers, and they can appear on the cloud layers that the temperatures are lower or higher The reason for disturbance is because electromagnetic waves are produced by geo stress action during earthquake preparation They have very wide frequencies If the frequency and strength is about carrier frequency near receiving antenna of satellite, it can produce stochastic resonance and result in disturbance of receiving data The observation data of our receiving station in more than one and half years time show that the abnormities obviously correspond to strong earthquakes It adds one new applied field of stochastic resonance of electromagnetic wave impending prediction Through further studies, we can design one kind apparatus used for catching earthquake precursors by stochastic resonance principle |
