We investigate the evolution of a flat Friedmann–Lemaitre–Robertson–Walker (FLRW) model equipped with the matter content induced by the fluid having equation of state depending on the parametric deceleration parameter. We reconstruct the universe which is composed of the dark energy and the non-relativistic matter. The universe transits from the decelerated phase dominated by the non-relativistic matter into an accelerated phase dominated by the dark energy. We single out the physically reasonable cases by checking the compatibility of the model to the observations. The model parameters are constrained by \(\chi ^2\)minimization technique. Based on the best fit values of the model parameters, evolution of the equation of state parameter, energy density, cosmographic parameters along with the role of the energy conditions are investigated in detail. The phantom dominated evolution may be realized during the future in reconstructed universe having the present age compatible with the model dependent estimates and the \(\Lambda \) cold dark matter model, subjected to the best fit values of the model parameters. And, the universe may lead to the little-rip singularity as \(z\rightarrow -1\) in the remote future.

我们研究了平面 Friedmann-Lemaitre-Robertson-Walker (FLRW) 模型的演化，该模型配备了由具有取决于参数减速参数的状态方程的流体引起的物质含量。我们重建了由暗能量和非相对论物质组成的宇宙。宇宙从非相对论物质主导的减速阶段转变为暗能量主导的加速阶段。我们通过检查模型与观测结果的兼容性来挑选出物理上合理的情况。模型参数受到\(\chi ^2\)最小化技术的约束。基于模型参数的最佳拟合值，详细研究了状态方程参数、能量密度、宇宙学参数的演化以及能量条件的作用。幻影主导的演化可能会在未来在具有与模型相关估计和\(\Lambda \)冷暗物质模型兼容的当前年龄的重建宇宙中实现，并受到模型参数的最佳拟合值的影响。并且，在遥远的未来，宇宙可能会导致小撕裂奇点\(z\rightarrow -1\) 。
