When the star explodes, the gas gets so hot and is compressed so violently by the blast that it undergoes fusion, what astronomers call explosive nucleosynthesis: literally, creating heavy elements explosively.

星爆炸时，气体会变得很热，并被猛烈地压缩，从而发生聚变，天文学家称之为爆炸核聚变：确切地说，就是爆炸般地产生重元素。

Here, the same r-process nucleosynthesis occurs - forming  heavier elements like gold, silver, and platinum.

在此，同样的快速中子俘获核合成过程（r过程）发生——形成金、银、铂等重元素。

Scientists used lasers to mimic stellar core processes of nucleosynthesis.

科学家们利用激光模拟了星核心的核聚变过程。

Starting from chance conversations with leading astronomers in the USA during an academic tour in 1944, he developed an idea that most chemical elements might be created step-by-step by nuclear reactions in stars, a process called nucleosynthesis.

源于1944年学术访问间与美国顶尖天文学家的偶然交谈， 他萌生了一个想法：大多数化学元素是通过星内部的核反应逐步合成的，这一过程被称为核合成。

If you think about the universe originated, atoms were made in Big Bang nucleosynthesis, and then later in stars, and then, planets formed and planets become engines of chemistry.

如果你思考宇宙的起源，原子是在大爆炸核合成过程中形成的，随后在星内部进一步生成，接着，行星得以形成， 而行星则成为了化学反应的引擎。 它们开始探索在的化学反应类型。

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

氦接着融合，形成了铍、碳和氧等较重的元素，这一过程被称为核合成。

Allowed matter to exist and then nucleosynthesis happened and made protons and neutrons and so on.

允许物质在，然后核合成发生了，产生了质子、中子等等。

It's actually this primordial nucleosynthesis soup from the beginning of the universe.

这实际上是来自宇宙开始的原始核合成汤。

According to the  big bang theory, primordial nucleosynthesis began when the universe was 3 seconds old.

根据大爆炸理论，原始核合成始于宇宙诞生后的3秒钟。

Nucleosynthesis works in one of two ways. It can start with protons and neutrons (or something even smaller) and bind them into a nucleus. Or it can start with a few lighter nuclei and fuse them into a heavier one.

核合成有两种方式进行。一种是从质子和中子（或更小的粒子）开始，将它们结合成一个原子核。另一种则是从几个较轻的原子核出发，将它们融合成一个更重的原子核。

As it gradually cooled down, fundamental particles emerged, and around 10 seconds to 16-20 minutes after the Big Bang, primordial nucleosynthesis occurred, giving rise to deuterium, helium, and lithium nuclei.

随着逐渐冷却， 基本粒子开始出现，在大爆炸后的10秒到16到20分钟内，原初核合成发生，产生了氘核、氦核和锂核。

It highlights the importance of understanding the processes that shape the relative  abundances of elements in the universe, and suggests that our current understanding  of nucleosynthesis might be incomplete.

这突显了理解塑造宇宙中元素相对丰度过程的重要性，并暗示我们对核合成的现有认识尚不全面。

You have this process called nucleosynthesis, where you're creating these heavier atoms.

你有一个叫做核合成的过程，在这个过程中你生成这些更重的原子。

Elements 2 through 26 on the periodic table  - that's helium to iron - are made this way, a process known as stellar nucleosynthesis.

周表中第2至26号元素——即从氦到铁——都是通过这种方式形成的，这一过程被称为星核合成。

Primordial nucleosynthesis produced two major chemical elements: hydrogen and helium.

原初核合成产生了两种主要化学元素：氢和氦。

This process is known as rapid neutron capture, or  r-process nucleosynthesis.

这一过程被称为快速中子俘获，即快速中子俘获核合成过程（r过程）。

Primordial nucleosynthesis produced two major chemical elements hydrogen and helium.

原初核合成产生了两种主要化学元素氢和氦。

So at this point, this sort of two-minute mark, this is when you get Big Bang nucleosynthesis.

所以在这一点上，大约两分钟的时候，就会发生大爆炸核合成。

And calculate how that big bang nucleosynthesis must have happened.

并计算那次大爆炸核合成必须是如何发生的。

There's another theory that collapsars like the BOAT could be another source  of r-process nucleosynthesis.

还有另一种理论认为，像史上最亮伽马射线暴这样的坍缩星是快速中子俘获核合成过程（r过程）的另一个来源。
