Sunspots increase and decrease in intensity in an 11-year cycle.

阳黑子以11年为一个周期增强和减弱。

Sunspots are only dark in relation to the bright material around them.

黑子的暗只不过是对应着周围明亮的物质而言。

The second study which suggests something odd is happening looked at the strengths of sunspots.

表明奇怪的事情正在发生的第二项研究检查了阳黑子的活力。

The areas of the strongest fields coincide exactly with the position of sunspots.

磁场最强的部位正好就是阳黑子的位置。

The Italian scientist Galileo was among the first astronomers to study sunspots.

大利科伽利略是最早研究阳黑子的天文之一。

Solar flares and coronal mass ejections often occur near sunspots.

阳耀斑和日冕物质抛射常发生在阳黑子附近。

OK, well, sunspots appear when very intense regions of magnetism rise to the sun's surface.

好吧 阳黑子出现在非常强烈的磁场区域上升到阳表面的时候。

Galileo was one the first modern scientists to observe sunspots.

伽利略是现代第一个观察阳黑子的科。

They also worked out that the latitude of this wind is related to the sunspot cycle.

他们还算出这次阳风的纬度和阳黑子的活动周期相关。

Sunspots are caused by irruptions into its surface of the sun's deeper magnetism.

阳黑子是由入侵活动进入阳深层磁性表面造成的。

Around the edges of sunspots, the magnetic field lines are concentrated.

在阳黑子的边缘，磁力线是集中的。

This cycle can be visibly measured by an increase and decrease of sunspots on its surface.

这个周期可以通过阳表面黑子的增减来进行明确测量。

What are sunspots and why are they dark?

什么是阳黑子，为什么它们是黑色的?

Not only does the Sun rotate, but sunspots themselves can actually spin like hurricanes on the solar surface.

不仅阳在旋转，而且黑子自身也会像飓风一样在阳的表面旋转。

" A direct measure of solar activity is the number of sunspots on the surface, " Reinhold said.

" 阳活动的一个直接测量方法是阳表面的黑子数量，" 莱因霍尔德说。

And the newer one also uses a secret formula based on mathematics, astronomy, sunspots, tides and the Earth's position.

它也使用了秘密公式，基于数、天文、阳黑子、潮汐和地球位置。

But using Koyama's record, they could precisely follow specific sunspots and clusters through that journey.

但利用小山的记录，在这一过程中，研究人员可以准确跟踪特定的黑子或黑子群。

What results are relatively dark blemishes on the solar surface called " sunspots" .

结果在阳表面形成了黑斑，称为“阳黑子”。

This creates a bright rim around sunspots called faculae (Latin for “little torch”).

这就在阳黑子周围形成了一圈亮边，被称为光斑（拉丁文的思是“小火炬”）。

The least sunspots in an 11-year period is considered solar minimum, while the most sunspot signifies the solar maximum.

阳黑子数量最少的11年时期被认为是阳活动极小期，而阳黑子数量最多的时期则代表阳活动极大期。
