详细研究了彼得罗巴甫洛夫斯克地球动力学试验场多年的大地电流监测资料。在分析结果中发现了与堪察加地震活动性有关的一些异常效应。这些异常效应归纳为:大地电场水平分量年变相位差的变化、持续时间从3～4天到1.5个月的湾形扰动、周期为1～6天的振荡型准周期变化、12小时和24小时的日变化正相关系数从1.0减小到0.3和在12小时内的周期性规律扰动变化。对所发现的一些异常效应的可能原因做了探讨。
The earth current monitoring data of the Petropavlovsk geodynamic experimental field for many years are studied in detail. Some of the anomalous effects associated with the Kamchatka seismicity were found in the analysis. These anomalous effects are summarized as follows: the change of phase change in the horizontal component of the earth electric field, the disturbance of the bay with the duration from 3 to 4 days to 1.5 months, the oscillation-type quasi-periodic change from 1 to 6 days, 12 hours and 24 hours The positive correlation coefficient of daily variation of hour decreases from 1.0 to 0.3 and the periodic disturbance changes within 12 hours. The possible causes of some abnormal effects discovered were discussed.
