原子核的

The nuclear magneton, calculated using the mass of the nucleon .

核磁子，用原子核的质量来计算

In the event of neutron capture, the mass number of the nucleus will be raised, and it will thus become unstable and radioactive.

一旦俘获了中子，原子核的质量数便会增加，因而也就会变得不稳定并且具有放射性。

Four years later he produced the first nuclear chain reaction, leading us into the nuclear age.

四年之后，他创造了第一次原子核的链反应，带领我们进入了原子时代。

Much of what we know about nuclei comes through scattering experiments.

我们现在对原子核的许多认识来自散射实验。

C. The study of the insides of atoms, or of atomic nuclei, is called nuclear science, or nucleonics.

对原子内部或原子核的研究称作核科学，或称核子学。

The study of the insides of atoms, or of atomic nuclei, is called nuclear science, or nucleonics.

对原子内部或原子核的研究称作核，或称核子学。三、不表示"二者居一"，而表示"二者均可"这时可译为"和"。例如

Because of this, the quality of helium-4 nucleus has been reduced.

正因为这样，氦4原子核的质量减少了。
