摘要：
本文报道了一项关于反弹宇宙学的研究，其中采用了一种受S. Nojiri和S. D. Odintsov（2017年，《欧洲物理杂志C》，77卷，第1-8页）启发的高度广义全息暗流体。这种主要用于晚期加速膨胀的全息暗流体被用于重构以实现宇宙学反弹。我们首先使用最广义的Nojiri-Odintsov（NO）截断来实现全息暗流体。据此，我们通过若干尺度因子解重构了这种暗流体。利用这些解，我们探讨了不同宇宙学参数的演化。我们在实现宇宙反弹的背景下考察了每个重构参数的影响。接下来，我们利用模型的标量谱指数、张量-标量比和慢滚特性的解析推断来研究反弹暴胀情景。由于暴胀通常与标量场的存在相关，我们考察了NO广义全息暗能量与标量场模型之间可能的关系，并绘制了由标量场产生的势随时间的演化图。最后，我们研究了反弹前和反弹后情景下热力学的广义第二定律（GSL）。
英文摘要：
The current work reports a study on bounce cosmology with a highly generalized holographic dark fluid inspired by S. Nojiri and S. D. Odintsov, 2017, European Physical Journal C, 77, pp.1-8. The holographic dark fluid that is mostly used for late-time acceleration has been implemented to reconstruct towards realisation of cosmological bounce. We first used the most generalized Nojiri-Odintsov(NO) cutoff to implement the holographic dark fluid. Accordingly, we have reconstructed this dark fluid via some solutions of scale factors. With those solutions, we have explored the evolution of different cosmological parameters. We have examined the effects of each reconstructed parameter in the context of the realization of the cosmic bounce. Next, we use the analytical inferences of the scalar spectral index, tensor-to-scalar ratio, and slow-roll characteristics of the model to study a bounce inflationary scenario. Since inflation is usually associated with the existence of scalar fields, we looked at a possible relationship between NO generalized holographic dark energy and scalar field models. Plotting the evolution of the potential that results from the scalar fields against time. Finally, we investigated the GSL of thermodynamics in the pre-and post-bounce scenarios.
