active-galaxies

基本解釋

A small percentage of galaxies called active galaxies emit tremendous amounts of energy.
有一小部分被稱做活動(dòng)星系的星系放射出巨大的能量。
So for years no one could be certain if supermassive black holes really did exist at the heart of these strange active galaxies.
因此這么多年仍無人能確定這些異常活躍的星系中心是否有超級(jí)黑洞.
The satisfactory performance for classification and knowledge discovery has been obtained by the proposed novel classifier over active galactic nucleus（AGNs） and active galaxies（AGs） data.
通過對(duì)活動(dòng)星系與活動(dòng)星系核實(shí)驗(yàn)表明，該方法無論對(duì)分類還是對(duì)知識(shí)發(fā)現(xiàn)都是非常有效的。
Galaxies can be divided into two classes: normal galaxy (NG) and active galaxy (AG).
星系通常分為正常星系(NG)與活動(dòng)星系(AG)兩類。
As a result, while the small, bright nucleus is typical of the Seyfert class of active galaxies, M94 is also known as a starburst galaxy.
在中心的小亮核心是典型的西佛星系(Seyfert)，而M94亦稱為星暴增星系。
