1996年11月17日至11月29日在新疆喀什地区8次地震期间观测到的震前发生的高频地磁脉动现象．文中对每次地震前的Pcl-2脉动的形态，以及脉动的起始时刻、持续时间、H分量和D分量的平均振幅随北京地方时的分布进行了详细研究分析．对这种震前观测到的高频地磁脉动的激发机制也做了深入的讨论．事实表明，这种震前发生的高频地磁脉动在地震的短期预报上可能有广泛的应用前景．
The observed phenomenon of high frequency geomagnetic pulsation occurred before the 8 earthquakes in Kashgar region of Xinjiang from November 17 to November 29, 1996. In this paper, the shape of Pcl-2 pulsation before each earthquake and the mean amplitude of pulsating initial time, duration, H-component and D-component are studied in detail with the distribution of Beijing local time. The excitation mechanism of the high frequency geomagnetic pulsation observed before the earthquake was also discussed in depth. The fact shows that this kind of high-frequency geomagnetic pulsation occurred before the earthquake may have a wide range of application prospects in the short-term earthquake prediction.
