Collectively, by the way, these particles are known as nucleons.

顺便说一下， 这些粒子统称为核子。

Because of this, we’ll often refer the two particles collectively as nucleons.

因此，通常把这些两个粒子统称为核子。

Because of this, we'll often refer the two particles collectively as nucleons.

因此，常常两种粒子的合体当作子核。

Topics that people use muons for range from fundamental constants of nature, basic symmetries, weak nucleon and nuclear interactions.

人使用 μ 子的主题范围从自然的基本常数、基本对称性、弱核子和核相互作用。

The mass number is just the total number of nucleons in the nucleus, which is different from atomic mass.

质量数只是子核中核子的总数， 它不子质量。

But even though those numbers of nucleons add up, remember: Mass and energy are equivalent.

但即便核中的数字被加总了，还是要记得：质能守恒。

Now, a unique part of beta decay is that no nucleons are emitted during the decay process.

现在，一个beta衰变的特别部分是当衰变产生时没有一个核子。

But while the total binding energy still increases for nuclei larger than iron, the binding energy per nucleon, in fact, decreases.

但是，虽然比铁更大的子核的总结合能仍在增加，每核子的结合能实际上是在减少。

While the strong force acts on nucleons, the weak force alters quarks, the fundamental particles that make up both protons and neutrons.

虽然强力作用核子，弱力则改变夸克，而夸克是构成质子和中子的基本粒子。

This decay occurs because the parent nucleus is too large, and the strong force is no longer sufficient to hold all the nucleons together.

这种衰变发生是因为母核太大，强力已经不足以所有核子紧密结合在一起。

That energy is what we mean when we talk about nuclear energy, the binding energy that's released when a nucleon is removed from its nucleus.

那种能量就是所说的核能，当一个核子从其子核中移除时释放的结合能。

The amount of energy required to break up a nucleus into its component particles gets larger as the atomic number increases, with iron having one of the highest binding energies per nucleon.

子核分解为其组成部分所需的能量随着子序数的增加而增大，铁的每核子结合能之一是最高的。
