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。 - 2
"The only remaining doubt," he said, "is whether massive stars of much higher mass, say 50 or 100 [solar masses], will form by the same accretion process." 唯一剩下的疑问是“，他说，”更大的星体，如50 - 100个太阳大小，是否也通过同样的积累方式形成的。 - 3
For decades, astronomers have been confident that relatively low-mass stars such as our sun form by the gradual accretion, or buildup, of mass from a disk of gas and dust. 几十年来，天文学家已经确信质量相对较小的星体，如我们的太阳，是逐渐积累或建立自碟状气体或尘埃而形成的。
