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。

The inner quantum orbital momentum of electron and the relative quantum distance between atomic nucleus and electron all relate to the quantum state of the atomic system.
