耀斑的短期生物效应

为研究太阳耀斑的短期生物效应,统计分析了198-199年中16万婴儿出生日与光学耀斑的关系. 结果表明,婴儿出生数的变化与耀斑辐射的能量,以及能量到达地球的时间有关. 太阳活动较平稳年白天爆发的各级耀斑的当天都对应着一个平均出生数高峰,而且耀斑的亮度和面积越大,对应的出生峰值越大. 2B耀斑当天平均出生数超过前后21d总均值的13.6髎,具有p＜0.001的统计高度显著性水平. 这些出生高峰与耀斑的电磁和高能辐射有关. 2B、2N和1B三类耀斑后的第2-4d还有一个出生峰,它们与耀斑引发的地球物理变化的时间符合.

SHORT-TERM BIOLOGICAL EFFECT OF FLARES

In order to investigate the short term biological effect of solar flares, the relation between the birthdays of the 160000 babies during 1985\_1995 and solar optical flares with different classes is analyzed by statistical method. The result shows that the everyday birth number is related to flare importance and the time when the radiation arrives at the earth. The birth peaks appear at the same days as flares occur during ordinary years, and the stronger flares are, the higher peaks are. The birth numbers at the days of 2B flares are 13.6% larger than average over 21 days before and after flares. The difference is high significance level with p <0.001. The second peaks appear within 2 nd \_4 th days after the stronger flares. The birth peaks on the flare days correspond with the time when electromagnetic radiation and the high energy particles from the flares reach the earth, and the second birth peaks are related to the geomagnetic storms and other change of the geophysical environment caused by flares.
