The experiment results show that the cover algorithm has good robustness and high classifying accuracy over Normal Galaxies and stars datasets.
对正常星系和恒星两类光谱数据进行实验，结果表明，覆盖算法具有较好的鲁棒性、较高的分类正确率。
Near the quasars in time are other, normal galaxies that have likely just passed through a quasar phase, as seen in images released earlier this month.
本月早些时候公布的一些图片显示，在类星体周围适时出现的，是其他那些正常的，刚刚经历了类星体阶段的星系。
Centaurus a is apparently the result of a collision of two otherwise normal galaxies resulting in a fantastic jumble of star clusters and imposing dark dust lanes.
半人马a可能是另两个正常星系碰撞的结果，碰撞产生了奇特的混杂星团和雄伟的暗尘带。
The observations and study of radio continuum radiation and HI radiation of normal galaxies carried out by the main observatories in the world in recent years is described.

It was no coincidence that the announcements of the two findings — distant quasars and normal galaxies — were made together at a meeting of the American Astronomical Society (AAS) Jan. 9.
在1月9日，美国天文学会的一次会议上，两个发现——关于遥远的类星体和常规的星系——被同时公布，这并不是巧合。
Such spectacular galactic mergers are now understood to be a normal part of the evolution of galaxies, including our own Milky Way.
这样壮观的星系合并现在已知是星系包括我们银河系演化中的普通情节。
Earlier this month, Windhorst and a colleague, Haojing Yan, released a Hubble Space Telescope image showing the most distant "normal" galaxies ever observed.
本月的早些时候，文德·霍斯特和他的一个同事，严浩静(音译)，发布了哈勃天文望远镜拍到的一些图片，这些图片展示出了曾经被观察到的大多数遥远的“正常”星系。
The merger process is now understood to be a normal part of the evolution of galaxies, including our own Milky Way.
