Definition of reactivity in English:

reactivity

noun rɪˈakˈtɪvɪtiˌriˌækˈtɪvədi
mass noun
  • 1The quality of being reactive or the degree to which something is reactive.

    反应性,反应率,反应度,反应能力

    the chemical and biological reactivity of non-target organisms
    in combination cross-reactivity between the hormones of human and bovine origin
    Example sentencesExamples
    • Once a worker is sensitized to an occupational agent, bronchial reactivity usually persists.
    • Acid reflux has been associated with bronchospasm, heightened bronchial reactivity, and airway edema.
    • In another asthma model, airway reactivity and lung inflammation were enhanced in the lung.
    • The chemical reactivity of titanium to the halides is similarly exhibited by its combination with their acids.
    • Finally, the qualitative data provide additional support for the notion of cue reactivity.
    • Interpretation relies on the presence or absence of reactivity to the specific antigens.
    • Skin test reactivity was also a significant predictor of maximal lung growth in those with respiratory symptoms regardless of sex.
    • Unfortunately, no postexposure measurement of bronchial reactivity was performed.
    • For the women who scored low on extraversion, no brain reactivity to positive stimuli was found.
    • Pituitary adenomas exhibited intense diffuse cytoplasmic reactivity.
    • Our results suggest that airway wall thickening attenuates airway reactivity in patients with asthma.
    • The effect of skin test reactivity remained significant for all symptoms except exercise-induced wheeze.
    • The most significant component in array validation is the comprehensive evaluation of cross reactivity.
    • Basically, it's a lot of airway reactivity and a lot of inflammation.
    • Thus, one manifestation of the lack of differentiation of self is emotional reactivity.
    • In its simplest form, it provides qualitative explanations for the formation and reactivity of molecules.
    • We measured the tracheal smooth muscle reactivity to methacholine.
    • The good news is that the change of a single amino acid in the major peanut allergen can reduce reactivity.
    • There was no evidence that the magnitude of the effect on allergen skin test reactivity differed between the three parasites.
    • In particular, we examined whether pulmonary function and nonspecific airway reactivity differed depending on atopic status.
    Synonyms
    responsiveness, sensitiveness
    1. 1.1 The extent to which a nuclear reactor deviates from a steady state.
      (核反应堆中核裂变的)反应率
      simulations predict that high rates of reactivity addition to the core could occur
      Example sentencesExamples
      • Because of the instability, an RBMK reactor that loses its coolant can under certain circumstances increase in reactivity and run progressively faster and hotter rather than shut itself down.
      • The temperature changes in turn modify the reactivity through different nuclear physics processes, which has a well defined influence on the number of neutrons ready to induce fission.
      • The spectrum of nuclear reactivity, including intensity and extent, was graded for all categories as shown in Tables 2 and 3.
