| 释义 | 〔luminescence〕The emission of light that does not derive energy from the temperature of the emitting body, as in phosphorescence, fluorescence, and bioluminescence. Luminescence is caused by chemical, biochemical, or crystallographic changes, the motions of subatomic particles, or radiation-induced excitation of an atomic system.发冷光：不是由于发光体的热量而来的光的发射，比如在磷光，荧光和生物性发光中。发冷光是由化学，生化或结晶变化，亚原子颗粒的运动，或原子系统的辐射产生的〔pyrimidine〕A crystalline organic base, C4H 4N 2, that is the parent substance of various biologically important derivatives. 嘧啶：一种晶状生物碱，C4H 4N 2，是多种生物性地重要衍生物的亲本物质 〔pyrrole〕A five-membered heterocyclic ring compound, C4H 5N, having an odor similar to chloroform.
