  • 在五维大反弹宇宙学模型框架下,通过给定三种不同的暗能量有效态方程,确定了在该模型中起重要作用的函数f(z),从而描述了五维大反弹模型中相关的宇宙学量随红移量z的演化.研究表明,与情形Ⅰ中有效态方程相对应的宇宙学量的演化规律和当前天文观测数据符合最好.

     

    Based on the five-dimensional cosmological model with a big bounce, by using the forms of the effective equation of state for dark energy,the expression of the interesting function f(z) is given in this model.Furthermore,the evolution of some cosmological quantities with the redshift z is presented. In addition, it is shown that the evolution of the dimensionless density parameters Ωdm, Ωde and deceleration parameter q for the first case is the best fit one,that consists with the present observations.
