| 单词 | 重子 |
| 释义 | 〔baryon〕Any of a family of subatomic particles, including the nucleon and hyperon multiplets, that participate in strong interactions, are composed of three quarks, and are generally more massive than mesons. Also called heavy particle See table at subatomic particle 激（发核）子，重子：微原子粒子家族中的一员，包括核子和超子多重谱线，由三夸克组成，一般比介子要重，会发生很强烈的内部反应 也作 heavy particle 参见 subatomic particle〔antibaryon〕The antiparticle of a baryon.反重子：重子的反粒子〔hyperon〕A semistable or unstable baryon with mass greater than the neutron. See table at subatomic particle 超子：一个不固定的重子，其质量比中子大 参见 subatomic particle〔proton〕A stable, positively charged subatomic particle in the baryon family having a mass 1,836 times that of the electron. See table at subatomic particle 质子：重子族群中一种稳定的带正电的中子核，质量为电子的1,836倍 参见 subatomic particle〔meson〕Any of a family of subatomic particles that participate in strong interactions, are composed of a quark and an antiquark, and have masses generally intermediate between leptons and baryons. See table at subatomic particle 介子：任一种具有较强相互作用力的亚原子粒子群，由一夸克与一反夸克构成，并具有通常介于轻子和重子间的质量 参见 subatomic particle〔neutron〕An electrically neutral subatomic particle in the baryon family, having a mass 1,839 times that of the electron, stable when bound in an atomic nucleus, and having a mean lifetime of approximately 1.0×103 seconds as a free particle. It and the proton form nearly the entire mass of atomic nuclei. See table at subatomic particle 中子：重子家族中电中性的亚原子粒子，是电子体积的1,839倍，作为自由粒子撞击原子核时保持稳定，平均寿命大约 1.0×103。它和质子几乎构成了整个原子核的质量 参见 subatomic particle〔hypercharge〕A quantum number equal to twice the average electric charge of a particle multiplet or, equivalently, to the sum of the strangeness and the baryon number.超荷：一个量子量，等于一个粒子多重线谱的平均电极；或者相当于量子数和重子的数量的总和〔isospin〕A quantum number related to the number of charge states of a baryon or meson.同位旋：与一个重子或介子的电荷状态数有关的一个量子数〔classon〕Either of two massless bosons, the photon and the graviton, that are quanta of the two classical fields, electromagnetic and gravitational. See table at subatomic particle 经典子：两种无质量的玻色子，即光子和重子中的任何一种，为两种经典场（电磁场和引力场）的量子 参见 subatomic particle |
