摘要
本文利用固体潮调制法，计算了近十年青海省的小震调制比，并提出了一种能够反映固体潮空间调制状态的调制块比，从而研究青海发生６．０级以上地震前这一参数的变化特点，实际情况表明，６．０级以上地震发生前调制块比都有一个从高值向低值的变化，并且在低值发震。也就是说空间受调制的区域面积由大变小时可能是青海省发生较大地震的信号。
The author has calculated the small earthquake modulated ratio, and has advanced a modulated piece ratio reflecting spatial modulated of earth tide by using tidal modulated method,thus studying its change character before Qinghai earthquakes with M≥6.0. The results show that the modulated piece ratios all changed from high value to low value before M≥6.0 earthquakes and occurring at low value. That is to see it is a possible signal of rather strong earthquake in Qinghai province when the regional area modulated in space from big to small.
