solar activity cycle

基本解釋

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周太陽活動(dòng)峰年期間，“太陽峰年”衛(wèi)星和“火鳥”衛(wèi)星上的硬x射線爆發(fā)探測(cè)器探測(cè)到數(shù)千個(gè)硬x射線太陽耀斑。
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.
我們發(fā)現(xiàn)頻率的變化隨著太陽內(nèi)部磁場(chǎng)強(qiáng)度增加而變大，并且和太陽活動(dòng)周期密切相關(guān)。
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.
簡(jiǎn)單來說，就是太陽的巨大磁場(chǎng)被用來進(jìn)行自我維持，所以，由其驅(qū)動(dòng)的太陽活動(dòng)周期將會(huì)在幾十億年的時(shí)間里維持整體上維持極小的變動(dòng)。
