摘要
研究了华南强震与太阳黑子、月相、地球自转和宇宙线GLE事件的关系,发现华南强震在太阳黑子活动周期中分布很不均衡,主要分布在峰段和谷段,这两段占76%,其中谷段占40~50%;由月相分布表明,阴历月份的初四和初十前后,是强震易发生时段,较之其它时段高3倍;此外,文中还给出华南强震与地球自转日长变化,宇宙线GLE事件等相关分析的初步结果。
The relations between sunspots, the phases of lunar month, the rotation rate of the earth and cosmic rays GLE are studied. The strong earthquakes distribution in South China is not very balanced at sunspot active periods, and most distribute at the peak and valley, about 76 percent, and 40~50 percent at the valley. The distribution of the phases of lunar month show that strong earthquakes easily occur before and after the fourth day or tenth day of lunar calendar, three times more than other periods. In addition, it is given that the preliminary results of the correlative analyses between the strong earthquakes in South China and the rotation rate of the earth, the cosmic rays,etc.
