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。
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。
