solar activity cycle

常见例句

During the 21st solar activity cycle the HXEBS aboard SMM satellite and the HXM on HINOTORI spacecraft detected several thousand hard X-ray solar flares.
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。
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。
