Sometimes, though, the sun sulks and this solar cycle stops.

然而，太阳有时也会生气，之后这种太阳活动周期就停止了。

So what causes the solar cycle?

那么是什么导致了太阳周期呢?

Until recently no-one knew what was driving the solar cycle.

我们到最近才得知太阳周期的原理。

No two solar cycles are the same, and often vary in activities.

没有两个太阳周期是相同的，而且太阳活动常常不同。

It was as if the engine that drives the solar cycle had stopped.

推动太阳周期的引擎仿佛熄火了。

And high-quality space-based observations go back just a decade—not even a full solar cycle.

而高质量的空间探测活动也才有十余年历史—甚至没有达到一个太阳活动周期的时间。

One group is suggesting that this next solar cycle could be the strongest in modern times.

一组认为下一个太阳周期会是现代最强的。

Right now, we're in the middle of a smaller 11-year solar cycle.

LATIF：现在，我们正处于一个较小的 11 年太阳周期的中间。

If we could better predict the timing and intensity of the solar cycle, more measures could be taken to protect from the sun.

如果我们能更好地预测太阳活动周期的时间和强度，就能采取更多的措施来保护我们免受太阳的伤害。

One of the biggest questions scientists are investigating now is how our host star's magnetic field affects its regular cycle of activity. It's called the solar cycle.

科学家们目前正在研究的最重大的问题之一是，我们的主恒星磁场如何影响其正常的活动周期。这被称为太阳周期。

" Also, sometimes the intensity is higher, sometimes lower. For example, the current solar cycle, as we call it, that we are in, is much lower than the previous one."

“有时其活动强度较大，有时较低，比如，目前我们所处的太阳活动周期其活动强度就比以前小。”

The starting point for Masdar was really working with nature, in terms of the solar cycle, making the greenery, not just a cosmetic greenery, but creating shade, burning the waste that we produce and, out of that process, creating energy.

建造马斯达的出发点是与自然协作，根据太阳活动周期种植树木，并不仅仅为了美观而是营造绿荫，而是消耗我们所产生的废物，并在这个过程中制造能源。
