在本文中，我们处理的Randall-Sundrum膜世界类型的场景中，五维外尔张量有一个非零的投影到三膜，在那里的物质场被限制的宇宙动力学。利用动力学系统技术，我们研究了Friedmann-Lema\^{\i}tre-Robertson-步行者和比安奇I型宇宙学模型的状态空间如何受到体Weyl张量的影响，重点讨论了与广义相对论和Randall-Sundrum宇宙学模型相比，在没有Weyl张量贡献的情况下出现的差异.
In this paper we deal with the cosmological dynamics of Randall-Sundrum brane-world type scenarios in which the five-dimensional Weyl tensor has a nonvanishing projection onto the three-brane, where matter fields are confined. Using dynamical systems techniques, we study how the state space of Friedmann-Lema\^{\i}tre-Robertson-Walker and Bianchi type I cosmological models is affected by the bulk Weyl tensor, focusing on the differences that appear with respect to general relativity and also Randall-Sundrum cosmological scenarios without the Weyl tensor contribution.
