摘要
利用磁流体力学的基本概念 ,试图对宇宙膨胀———总星系扩张的动因 ,提出另类物理解释如下 :磁压是导致磁力线疏散的一种斥力。由于宇宙磁场是冻凝场 ,故当磁力线在空间疏散时 ,必将带着与之冻结的宇宙物质一起在空间疏散 ;从而使宇宙物质的密度减少 ,各星彼此远离。因此可以认为 ,磁压是宇宙膨胀的主要动因。并就有关问题进行了讨论。
Using the concepts of magnectohydrodynamics,an attempt to propose a different physical interpretation on the cosmic expansion(metagalaxy extension)agent was made as follows.The magnectic pressure is a repulsive force which causes megnectic lines of force scattering.Bacause the cosmical magnectic field is a frozen field,therefore while the magnectic lines of force is scattering in the space,they will drive the cosmical matter,which is frozen in the magnectic field,scattering togather with them in the space,and thus make the density of metagalactic matter reduce and the galaxies scatter away from each other.Therefore,it might be considered that the magnectic pressure is the main agent of cosmic expansion.Finally,some related problems have also been dicussed.
