中文摘要	本文研究赤道异常逐日起伏程度的年变化规律,发现它与太阳活动及地磁活动呈微弱的负相关,但却受到QBO的明显调制,QBO东风相起伏加大,QBO西风相起伏减小.这一事实似乎表明,太阳爆发或磁暴不是产生赤道异常逐日起伏的主要原因;而上行行星波的扰动有可能是引起赤道异常逐日起伏的主要原因.
英文摘要	The yearly variation of the day-to-day variability of the equatorial anomaly have been investigated. It is revealed that this yearly variation is modulated by the QBO, (in east phase of the QBO the day-to-day variability of the equatorial anomaly increases, in west phase of the QBO it decreases), but negatively correlated with the solar activity. It implies that the day-to-day variability of the equatorial anomaly is not caused by the solar bursts and/or geomagnetic storms, but the disturbances of the upward propagating p1anetary waves．In contrast，the yearly intensity variation of the fluctuation(or day—tO—day variability)of the 10F2 in middle latitude is not modulated by the QnO ’but correlated tO the geomagnetic activity with solar cycle．
