在第21周太阳活动峰年期间，“太阳峰年”卫星和“火鸟”卫星上的硬x射线爆发探测器探测到数千个硬x射线太阳耀斑。
The frequency shifts is found to increase with the strength of magnetic fields in solar interior, and its temporal behavior closely follows the phase of the synthetic solar activity cycle.
我们发现频率的变化随着太阳内部磁场强度增加而变大，并且和太阳活动周期密切相关。
The scientists concluded that the solar wind activity must follow the same cycle.
科学家们得出结论，太阳风的活动必须遵循相同的周期。
If a change in the jet stream really is a leading indicator of solar activity, then no new cycle is on the horizon.
如果高速气流的变化真地是太阳活动最重要的指示物，那么新的太阳活动周期还未露端倪。
Scientists also believe it may also be possible that during the next upturn of the cycle, when solar activity increases, there might be a cooling effect at the Earth's surface.
科学家们相信，在周期的下一个上升期，也就是在太阳活动趋于频繁时，可能会对地球表面产生冷却效应。
While solar activity is currently increasing in its standard 11-year cycle, this same cycle has occurred over millennia.
虽然，太阳活动目前在其标准的11年周期中逐渐增加，这种固定的周期持续了几千年。
Most astronomers think that the solar cycle will proceed, but at significantly depressed levels of activity similar to those last seen in the 19th century.
大多数天文学家认为太阳活动周期会持续，但强度会发生严重的下滑，相比19世纪所看到的那样。
Solar activity rises and falls on a regular cycle of about 11 years.
太阳的活跃程度按照一个11年代周期涨落。
The sun is currently approaching what's known as solar maximum, the peak of our star's roughly 11-year cycle of magnetic activity.
因为目前的太阳正逐渐接近它的“活动峰年”，也就是周期约为11年的地磁活跃高峰期。
In short, the Sun's large-scale magnetic field is taken to be self-sustaining, so that the solar-activity cycle it drives would be maintained with little overall change for perhaps billions of years.
简单来说，就是太阳的巨大磁场被用来进行自我维持，所以，由其驱动的太阳活动周期将会在几十亿年的时间里维持整体上维持极小的变动。
