宇宙加速度与哈勃参数的变化
Cosmic acceleration and the change of the Hubble parameter
摘要：
提出了一个新的宇宙加速膨胀模型。得到了真空中的de Sitter解和尘埃源下的精确解。对宇宙膨胀的加速给出了新的解释。证明了宇宙膨胀从减速到加速的变化是宇宙的一种内在性质，而不需要暗能量。
英文摘要：
A new model of accelerating expansion of the universe is presented. A de Sitter solution in vacuum and a exact solution with the dust mater source are obtained. A new explanation of the acceleration of the cosmic expansion is given. In is proved that the changing of the expansion from decelerating to accelerating is an intrinsic property of the universe without need of dark energy.
