释义

Definition of quantum chromodynamics in English:

quantum chromodynamics

(also QCD)
plural nounkrəʊməʊdʌɪˈnamɪks
Physics
  • treated as singular A quantum field theory in which the strong interaction is described in terms of an interaction between quarks mediated by gluons, both quarks and gluons being assigned a quantum number called ‘colour’.

    〔物理〕量子色动力学

    Example sentencesExamples
    • Today the other three forces are described by the gauge theories of quantum chromodynamics and quantum electrodynamics, which together make up the Standard Model of particle physics.
    • Then similar wisdom was applied to the strong nuclear force to yield quantum chromodynamics, or QCD, and this theory was also renormalizable.
    • The theory of the strong interaction between quarks - quantum chromodynamics - is approximately invariant under what is called charge symmetry.
    • Everyone agrees that the fundamental theory of the strong interaction is a quantum field theory known as quantum chromodynamics, or QCD for short.
    • The theory of strong interactions, known as quantum chromodynamics, is well-developed and consistent with experiments, although it is not easy to test it very precisely.
