论文摘要
在本文中，我们用弗里德曼方程来描述宇宙的演变，该方程考虑了宇宙的组成和几何形状。讨论了解决方案对基本成分不同组成组合的几何形状和组成的依赖性。确定了宇宙时间演变的独特行为，并提出了标准宇宙学预测的场景。
In this paper we describe the evolution of the Universe in terms of the Friedmann equation, which takes into account of the composition and geometry of the Universe. The dependence of the solution on the geometry and composition for different combinations of the basic constituents are discussed. The distinct behaviors for the temporal evolution of the Universe are determined and the scenario predicted by the Standard Cosmology is presented.
