霍金温度的修正对半全息宇宙学模型的影响

摘要

This article modifies the general form of Hawking temperature ,and basing on the dynamic effect of second derivative in scale factor a , it reconsiders the coincidence of the ratio of dark energy and dark matter as well as the acceleration of the universe under semi‐holographic cosmological models ,obtains the kinetic equation of the universe and its attractor solution ,and provides the analytical expression of deceleration factor and the equivalent pressure density ratio . After adopting some reasonable parameters , when the deceleration factor is negative , it indicates that the universe is accelerated expanding ,The equivalent pressure density ratio of dark energy and dark matter is well consistent with the prospection of semi‐holographic cosmology .%文章修正了霍金温度的一般形式，基于其表达式中标度因子 a的二阶导数项的动力学效应，重新讨论了半全息宇宙学模型下暗能量和暗物质比例的巧合性问题与宇宙加速问题，得到了宇宙动力学方程及其吸引子解，并给出了宇宙减速因子和等效压强密度比的解析表达式。在给定合理的参数后，宇宙减速因子取负值，表明当前的宇宙正在加速膨胀，同时暗能量和暗物质的等效压强密度比也符合半全息宇宙学的预期结果。
