【摘要】 总结了能够引起电离层扰动的各种因素,包括太阳活动、地磁活动、大气波动、剧烈天气以及其它方面(例如地震、火山以及人类活动等);提出了地震电离层前兆研究的一般步骤流程:地震事例筛选—电离层观测参量筛选—异常识别与提取—地震电离层前兆确认;介绍了目前地震影响电离层的三种可能途径:化学、机械波和电磁途径;总结了地震电离层前兆地基和天基监测手段;最后提出了地震电离层前兆研究的几个重点需要解决的问题。更多还原

【Abstract】 The factors associated with the inonspheric disturbance are summarized,including solar activity,geomagnetic activity,atmospheric waves,severe weather and others (earthquake,volcano and human activity etc).The common step flows researching the ionospheric phenomena before strong earthquakes are expounded:filtrate the earthquake examples—choose the parameters of the ionosphere—identify and distill the singular information—validate the ionospheric response of the pre-earthquake.The possible three mechanisms are introduced:chemistry,mechanism wave and electromagnetism.The detecting means of ground-based and space-based are presented.Finally,several issues on the seismo-ionospheric precursor are advanced.更多还原
