It's creating these little micro bubbles called nucleation sites.

它产生这些小气泡称点。

Then each peanut becomes what is called a " nucleation site."

后，每颗花生就变了所谓的“点”。

The nucleating agent can improve the degree of crystallinity .

剂可以提高结晶度。

These spots are called nucleation sites.

这些点称点。

So once that bubble of true vacuum nucleates, once it starts, that bubble expands at about the speed of light.

因此， 一旦那个实空的气泡开始，一旦它启动， 这个气泡就会以接近光速的速度扩张。

And another option where the early universe, underwent a period of rapid expansion and then different universes bubbled and nucleated off like soap bubbles in a foam.

还有另一种选择，早宇宙经历了一段快速膨胀的，后不同的宇宙像泡沫中的肥皂泡一样冒泡和。

That’s a nucleation site--it could be a fiber or dust particle on the glass, an imperfection or bump, or even a tiny trapped air bubble.

那是一个点——它可能是玻璃上的纤维或灰尘颗粒、缺陷或凸起，甚至是微小的气泡。

There is a theory – although still far from  certain – that this extra radiation could be creating nucleation sites in the atmosphere  that seed extra clouds, influencing our weather.

有一种理论（尽管还远未确定）认， 这种额外的辐射可能会在大气中产生位点， 从而产生额外的云层，从而影响我们的天气。
