Requirement to Hubble Constant from the Ia Supernova;

基于Ia型超新星理论的哈勃常数

This paper reviews the origin,history and recent status of the age puzzle,with particular emphasis on the role of the measured value of the Hubble constant in the cosmic age problem.

重点讨论了哈勃常数的实测值大小在宇宙年龄问题中的核心作

The four-velocity of ideal fluid and the calculating formula of Hubble parameter in the standard cosmology are generally used in the discussion on the bulk viscous cosmology in the literatures This paper demonstrates the reasonableness of these disposals by the energy-momentum tensor of bulk viscous fluid and Einstein s equation of the gravitational fiel

在对体积粘滞宇宙论进行探讨时，文献中普遍使用理想流体的４－速度和标准宇宙论的哈勃参量的计算公式，现使用体积粘滞流体的能量－动量张量和Ｅｉｎｓｔｅｉｎ引力场方程论证了这一作法的合理性

Then, the ansatz for the Hubble parameter is considered by basi.

其次，通过运用一个含多参数的哈勃参量，我们构造了一个多参数的暗物质与暗能量的统一模型，从而使该模型与观测数据相符。
