The electron back bombardment phenomenon, which results in anomalous increase of gun current emission, has been observed in a series of our side coupled standing wave accelerating tubes.
The paper also has discussed the problem on earthquake prediction by telluric current method based on the anomalous phenomena of earth resistivity of the 6.1 earthquake.
文中还就6.1级地震的地电异常现象讨论了地电方法预报地震的问题。

The anomalous variations of micro-current before this two earthquakes are obvious. The anomalous amplitude is 10~20 times higher than that of ordinary background.
