摘要
舒曼谐振位于地球-电离层空腔，具有稳定的频率和强度特征尺度。震前的舒曼谐振异常是地震引发电离层异常的现象之一。本文概括了舒曼谐振的产生机理、特征参数的稳定性，并介绍了常用的测量仪器等。总结了震前舒曼谐振异常的研究进展，包括统计分析和震例分析的结果，归纳了舒曼谐振异常在频率、强度、极化等方面的特征表现，并对未来的研究方向和研究手段等进行了讨论。
Schumann resonance lies in the earth-ionosphere cavity with stable frequency and characteristic intensity scales. Schumann resonance anomaly before earthquakes is one of the seismo-ionospheric anomalies. In the last few years, research in Japan on this field has aroused the attention of the researchers of seismic electromagnetics in the world. This paper introduces the generation mechanism, characteristic parameters and the measurement instruments of Schumann resonance. The research progress including the results of statistical and seismic case analysis is summarized. The characteristic manifestations of Schumann resonance anomalies in frequency, intensity and polarization are concluded. And some future research directions are suggested.
