黏附引力成团引起大尺度结构的稳定性(英文)

STABILIZATION OF LARGE SCALE STRUCTURE BY ADHESIVE GRAVITATIONAL CLUSTERING

多流体介质中引力和弥散力间的相互作用产生一种效应 ,研究结果表明此效应乃是大尺度结构稳定性的真正驱动力。“黏附引力成团”构想的提出 ,是为了将大尺度结构形成的已经被很好地理解了的时期同维里化的起始联结起来 ,该维里化的产物是和作为其存在之环境的大尺度结构处于动力学平衡之中的。经典的“黏附模型”同一组根据动力学理论中黏附力的物理起源而提出的更加一般的模型是不相容的。

The interplay between gravitational and dispersive forces in a multi-streamed medium leads to an effect which is exposed in the present note as the genuine driving force of stabilization of large-scale structure. The conception of ‘adhesive gravitational clustering’is advanced to interlock the fairly well-understood epoch of formation of large-scsle structure and the onset of virialization into objects that are dynamecally in equilibrium with their large-scale structure environment. The classical ‘adhesion model’ is opposed to a class of more general models traced from the physical origin of adhesion in kinetic theory.
