| 释义 | boson (once / 53002 pages) n A boson is a nuclei with an even mass number. Bosons are subatomic particles. An atom isn’t the smallest thing in the world: there are also subatomic particles, such as bosons. Bosons get their name from Indian physicist S. N. Bose, who first described their behavior. If you want to understand bosons thoroughly, you'd better take a class in in particle physics. In a nutshell, a boson has a symmetric wave-function, therefore obeying Bose-Einstein statistics but not the Pauli exclusion principle. Physicists study bosons to understand how the universe works at the tiniest level. WORD FAMILYboson: bosons USAGE EXAMPLESMaybe this seems humble alongside other winning physics breakthroughs: radiation, quantum mechanics, semiconductors, the Higgs boson. Slate(Dec 27, 2016) Bose–Einstein condensates comprise bosons, particles that have either zero or integer values of spin, that are all in the same spin state. Nature(Oct 18, 2016) They call this elusive beast the “Higgs bison” after the Higgs boson particle that was finally discovered after 48 years of speculation. Science Magazine(Oct 18, 2016) n any particle that obeys Bose-Einstein statistics but not the Pauli exclusion principle; all nuclei with an even mass number are bosons Hypo|Hyper gauge boson a particle that mediates the interaction of two elementary particles meson, mesotronan elementary particle responsible for the forces in the atomic nucleus; a hadron with a baryon number of 0 b-mesonexceedingly short-lived meson gluona gauge boson that mediates strong interaction among quarks gravitona gauge boson that mediates the (extremely weak) gravitational interactions between particles intermediate vector bosona gauge boson that mediates weak interactions between particles J particle, psi particlea neutral meson with a large mass K particle, k-meson, kaon, kappa-mesonan unstable meson produced as the result of a high-energy particle collision photona quantum of electromagnetic radiation; an elementary particle that is its own antiparticle pi-meson, piona meson involved in holding the nucleus together; produced as the result of high-energy particle collision particle, subatomic particle a body having finite mass and internal structure but negligible dimensions |
