But as the Universe cooled, for a brief time, they could fuse and form heavier elements.

但随着宇宙冷却，在短时间内，它们会发生聚变，形成更重的元素。

Their age can be found by looking at ratios of elements in them formed from radioactive decay.

它们的年龄可以通过观察由放射性衰变形成的元素的比例而发现。

These conditions last for just 15 seconds, but it's enough to form the heaviest elements like gold.

这种情况只能持续大约 15 秒，但是已经足够产生一些重质基本元素了，比如说金元素。

Helium, in turn, fused to form heavier elements, like beryllium, carbon and oxygen in a process known as nucleosynthesis.

反过来，氦在称为核合成的过程中融合形成更重的元素，如铍、碳和氧。

Using atoms and molecules, you build your body, forming basic elements into a form that you call your own.

使用原子和分子，您构建自己的身体，将基本元素形成您称之为自己的形式。

Rather, it caused the atom to split, forming lighter elements in the process, and also releasing a tremendous amount of energy.

相反，它导致原子分裂， 在此过程中形成更轻的元素，并释放出巨大的能量。

A humble yellow dwarf, emitting energy from x-ray to radio like breath exhaling form its ionized elements, From hydrogen to iron.

一颗不起眼的黄矮星，从 X 射线到无线电发射能量，就像从氢到铁的电离元素呼出的气息。

That new element can grab neutron after neutron, some occasionally decaying into protons along the way, forming heavier and heavier elements.

这种新元素可以一个接一个地抓住中子，其中一些偶尔会衰变成质子，形成越来越重的元素。

The light given off by one merger 900 million light-years away confirmed that heavy elements like gold do form during these violent events.

9 亿光年外的一次合并发出的光证实了在这些剧烈事件中确实形成了像黄金这样的重元素。

Since absolute enthalpy is unknowable though, we have to be measuring from a baseline, and that baseline is that individual elements' most stable form at standard state.

由于绝对焓是不可知的， 我们必须从基线开始测量，而该基线是单个元素在标准状态下最稳定的形式。

Well, the blood that flows from your arm into that bag is whole blood, a mixture of cells and cell fragments called formed elements, along with water, and lots of dissolved molecules.

嗯，从你手臂流入袋子的血液是全血，细胞和细胞碎片的混合物，称为形成元素，还有水，和许多溶解的分子。

The universe when it first started out was pretty much entirely composed of Hydrogen, which came together into stars and that Hydrogen fused together to form Helium and the Helium fused together to form larger and larger elements.

最初的宇宙几乎完全由氢组成，氢汇聚成恒星，氢聚变形成氦，而氦聚变形成越来越大的元素。
