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介子的質量較大，使得μ 氫具有較小的原子尺寸和與質子相互作用更強烈。 - 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，一個碳12質量的1／12爲一個原子質量單位，近似等於一個質子或中子的質量，又稱相對原子質量。
