Abstract
Abstract In this paper we consider a correspondence between holographic dark energy density and extended Chaplygin gas energy density proposed by Pourhassan and Kahya [2014] (Advances in High Energy Physics, 231452, 2014) in FRW universe. We solve the Friedmann equation and investigate the be- haviour of cosmological parameters and also we reconstruct the potential and dynamics of the scalar field which describe the extended Chaplygin gas cosmology.
本文考虑了FRW宇宙中全息暗能量密度与Pourhassan和Kahya [2014] (Advances In High energy Physics, 231452, 2014)提出的扩展Chaplygin气体能量密度的对应关系。我们求解了弗里德曼方程，研究了宇宙学参数的be-行为，并重建了描述扩展的查普金气体宇宙学的标量场的势和动力学。
