太阳极大期

甚至于以往的太阳活动极大期相比逊色不少。“与之前的五六次太阳活动周期相比，这一次势头太弱了”，这是耶鲁大学的天文学家塞巴尼·巴苏在于本月3日波斯顿举行的第24届美国天文学会上作出的评论。

In fact , this latest solar max has been a bit of a dud . " Compared to say the five or six previous cycles , this is really weak . " That 's astronomer Sarbani Basu of Yale University , at the 224th meeting of the American Astronomical Society in Boston on June 3rd .

我们不妨谈谈有关太阳黑子极小和极大期的推导。

We might add a remark about the derivation of the epochs of the sunspot minima and maxima .

太阳活动由太阳大气中的电磁过程引起，时强时弱，平均以11年为周期，活动剧烈期的太阳活动有太阳黑子和耀斑。而现在我们本应该处于一个太阳活动极大期。

Every 11 years , the sun 's magnetic activity ramps up , sometimes to a frenzy , causing large Right now we should be in the middle of such a solar maximum .
