dark halo meaning in English

暗晕

Then , we analyse in detail the mass - accretion histories and structural properties of dark haloes in high - resolution n - body simulations
本文利用高分辨率的n体数值模拟仔细分析了暗晕的质量吸积历史和内部结构演化历史。
Ms , for all its main progenitors , which is the basic reason why halo structural properties are closely related to their mass - accretion histories . this correlation can be used to predict the structural properties of a dark halo at any time in its history
我们建立了模型，利用该相关关系和暗晕质量吸积历史来预言其内部结构的演化，该方法无论从统计上还是对单个暗晕均达到了很高的精度。
The build - up of dark haloes in cdm models generally consists of an early phase of fast accretion [ where the halo mass mh increases with time much faster than the expansion rate of the universe ] and a late phase of slow accretion [ where mh increases with time approximately the same as the expansion rate ]
我们同时发现： ( 1 )冷暗物质模型( cdm )中暗晕的成长均包括一个早期的快速吸积阶段[暗晕质量m _ h随时间的增长远快于宇宙的膨胀速率和一个晚期的缓慢吸积阶段
