circular velocity meaning in English
环流速度
圆速度
圆形轨道速度
圆周速度, 环绕速度
Examples
- These two phases are separated at a time when the halo concentration parameter c ~ 5 and the binding energy of the halo is approximately equal to that of a singular isothermal sphere with the same circular velocity
肠‘随时间的增长和宇宙的膨胀速率基本一致: ( 2 )在这两个阶段的分界点处暗晕的汇聚因子。 - Haloes in the two accretion phases show systematically different properties , for example , the circular velocity vh increases rapidly with time and approximately equals the inner circular velocity vs in the fast accretion phase , but remain almost constant and less than vs in the slow accretion phase : the inner properties of a halo , such as rs and ms increase rapidly with time in the fast accretion phase but change only slowly in the slow accretion phase : the halo concentration changes slow in the fast accretion phase , but increases rapidly with the hubble expansion in the slow accretion phase . the inner structure and potential well associated with a halo is built up mainly in the fast accretion phase , while a large amount of mass can be accreted in the slow accretion phase without changing significantly the inner properties and the potential well
~ 4 ，其束缚能和具有相同圆周速度的等温球大致相等; ( s )在这两个阶段，暗晕的行为特征迥异(例如，圆周速度均‘在快速吸积阶段增长迅速且略大于内部圆周速度: 、 ，而在缓慢吸积阶段基本恒定甚至降低，且小于、 、 . : 、和呱在快速吸积阶段增长迅猛，而在缓慢吸积阶段增长滞缓) : ( l )一个暗晕的内部结构和引力势阱主要是在早期的快速吸积阶段成长起来的，虽然在缓慢增长阶段可以吸积大量的质量(超过10倍) ，但这并不显著地改变其内部特征和引力势阱
