The model with substructures can suppress the luminous central galaxy formation in cluster and can give a better luminosity function compared with the observation. 考虑到次结构一方面可以降低中心星系的亮度,同时能预言与观测很接近的光度函数形状。
During this time, the bar prevents fresh gas from entering the central part of the galaxy. 在这段时间里,星棒阻止了新鲜气体进入星系的中心地带。
For central part of the Galaxy, the projected surface density has increased about 9 % more than that given by Too-mre's model. 对银河系中心部分,投影面密度值比Toomre公式给出的密度值约高9%。
Arching across the sky is the central band of our Milky Way Galaxy. 拱状划过天空的则是银河系的中央地带。
A university in one of the rising central cities faces both the challenge from a galaxy of key universities and that all over the world in the competition for qualified personnel. 作为呈崛起之势的一批中心城市的高等学校,面临着重点高校林立和来自全球范围人才竞争的挑战。
