论文摘要
由宇宙深色液体主导的宇宙的一般无关流体流动引起的一般性液体流体考虑，将根据时空剪切的性质进行研究。特别重点将放在准牛顿和抗牛顿的线性扰动上，在这种空间中，将在存在和讨论Chaplygin气体模型的情况下存在这种空间的存在和一致的变化。
Integrability conditions arising from general irrotational fluid-flow considerations of a universe dominated by cosmic dark fluids will be investigated under special assumptions on the nature of the spacetime shear. Special emphasis will be placed on linearized perturbations of quasi-Newtonian and anti-Newtonian spacetimes, whereby the conditions for the existence and consistent evolution of such spacetimes in the presence of the Chaplygin gas fluid model will be derived and discussed.
