【摘要】 分析太阳活动第２２周峰年期（１９８８～１９９１）内７４８个较大耀斑的时空分布规律，发现耀斑频次具有双峰性；分布具有南北不对称性；大耀斑与全球≥６级地震具有“群一震”性，并指出在峰年期，地震活动增强．更多还原

【Abstract】 The time-space distribution properties of 748 large solar flares for the 22-nd maximum of solar activity(1988￣1991)are studied in this paper.The double maximum of solar flare frequency,south-north nonsymmetry of solar flare are revealed.The “solarflare group-earthquake”relation between the lage flare and the whole world earthquake(≥6 class)are also revealed.Writer consider that earthquake activity will multiply when solar activity tend to become maximum.更多还原
