proton atomic mass
常见例句
- The muon's larger mass gives muonic hydrogen a smaller atomic size and allows a much larger interaction with the proton.
μ介子的质量较大，使得μ 氢具有较小的原子尺寸和与质子相互作用更强烈。 - As a result, 1/12 the mass of a carbon 12 atom is called one ATOMIC MASS UNIT, which is approximately the mass of one PROTON or one NEUTRON. Also called relative atomic mass.
因此，一个碳12质量的1／12为一个原子质量单位，近似等于一个质子或中子的质量，又称相对原子质量。
