太阳自转

具有明显的与太阳自转相关的27天左右的变化和明显的与行星波有关的接近16日、10日、5日、2日等短周期变化。

A.E.L.Davis在这周告诉天文学家和历史学家说，正是太阳自转现象让开普勒得到启发，从而得出他在行星运行定律中所描述的引起行星运动的其中一个原因，尽管他的论证过程在现在看来是完全错误的。

A.E.L. Davis this week told astronomers and historians that it was the rotation of the sun that provided Kepler with what he thought was one of the causes of the planetary motion that his laws described , although his reasoning would today be considered entirely wrong .

当太阳的自转使这个波浪形间隔面扫过地球时，我们就会探测到磁场极性的突然反转。

When the sun 's rotation sweeps this warped surface across the earth , we detect sudden changes in the polarity of the magnetic field .

当他得知太阳存在自转现象时，他就自欺欺人地认为太阳的光线无论如何一定会照射到周围的行星，而某种磁力使堡这些行星沿着规则的椭圆轨道运行。

Once he learned that the sun rotated , he comforted himself with the thought that the sun 's rays must somehow sweep the planets around it while some magnetism accounted for the exact elliptical path .

实际上，太阳也会自转。

As a matter of fact , the sun turns too .
