radiance(n.)
大约在1600年,"brilliant light, brightness shooting in diverging rays or beams"这个词从 radiant (形容词)或者从中世纪拉丁语的 radiantia "brightness"中演变而来, radiantia 源于 radiare "to beam, shine" (参见 radiation)。在1761年,这个词开始被用于比喻美丽、快乐等。相关词汇: Radiancy。
Radiance ... is generally a light that is agreeable to the eyes; hence the word is often chosen for corresponding figurative expressions: as, the radiance of his cheerfulness; the radiance of the gospel. Brilliance represents a light that is strong, often too strong to be agreeable, and marked by variation or play and penetration : as, the brilliance of a diamond or of fireworks. [Century Dictionary]
Radiance ...通常指的是对眼睛有益的光线; 因此,这个词经常被用于相应的比喻表达:例如,他的快乐就像 radiance; 福音的光辉就像 radiance。Brilliance 代表的是强烈的光线,通常过于强烈以至于不太令人愉快,并且具有变化或游戏和穿透性:例如,钻石或烟火的 brilliance。[世纪词典]
