释义 |
反粒子fǎnlìzǐ正电子、反质子、反中子、反中微子、反介子、反超子等粒子的统称。反粒子与所对应的粒子在质量、自旋、平均寿命和磁矩大小上都相同;如果带电,两者所带电量相等而符号相反,磁矩和自旋的取向关系也相反。反粒子与所对应的粒子相遇就发生湮没而转变为别的粒子。{antiparticle; any constituent particle of antimatter; general term for par-ticles as positive electron, antiproton, antineutron, antineutrino, antimesotron, antihyperon, etc. An antiparticle and its corresponding particle are the same in quality, rotation, average lifespan and magnetic torque. When charged, the two have the same electrical charge in reverse directions, and this also applies to magnetic torque and rotation. When an antiparticle and its corresponding particle meet, they will combine and become other particles.} |
