luminosity
Significado: The intrinsic brightness of a celestial body or other light source, measured as the total amount of energy emitted per unit of time. More broadly, the quality or state of emitting light.
In astrophysics, luminosity is an absolute measure — it describes how much energy a star radiates regardless of distance, distinguishing it from apparent brightness, which depends on the observer's position. In art and literary criticism, the word is used metaphorically to describe radiance or brilliance. In particle physics, luminosity measures the rate at which collisions occur in an accelerator. The term collocates with 'stellar,' 'solar,' and 'function.'
Ejemplos
- The luminosity of the newly discovered supergiant exceeds that of our sun by a factor of several hundred thousand. 这颗新发现的超巨星的光度超过我们太阳的数十万倍。La luminosidad de la supergigante recién descubierta supera la de nuestro sol en un factor de varios cientos de miles.新たに発見された超巨星の光度は、太陽の数十万倍に達する。새로 발견된 초거성의 광도는 태양의 수십만 배에 달한다.
- Turner's later paintings are celebrated for the luminosity of their skies, which seem to glow with an inner radiance. 透纳晚期的画作因其天空的光辉感而备受赞誉,那些天空仿佛散发着内在的光芒。Los últimos cuadros de Turner son celebrados por la luminosidad de sus cielos, que parecen irradiar un resplandor interior.ターナーの後期の絵画は、内側から輝くような空の光輝で高く評価されています。터너의 후기 회화는 내면에서 빛나는 듯한 하늘의 광휘로 높이 평가받고 있습니다.
