We investigate the chameleon Brans–Dicke gravity with new holographic dark energy which includes a non-minimal coupling between matter and scalar field. We use parameterized forms of deceleration parameter for flat FRW universe, which play a vital role to describe the nature of cosmic acceleration. We explore the cosmological parameters like Hubble parameter, equation of state parameter as well as its plane and stability of the obtained solution. The results of cosmological parameter and plane are consistent with observational data.

具有参数化减速参数的变色龙 Brans-Dicke 引力的宇宙方面

我们用新的全息暗能量研究变色龙 Brans-Dicke 引力，其中包括物质和标量场之间的非最小耦合。我们对平面 FRW 宇宙使用参数化形式的减速参数，这对描述宇宙加速的性质起着至关重要的作用。我们探索了哈勃参数、状态方程参数等宇宙学参数及其平面和所获得解的稳定性。宇宙学参数和平面的结果与观测数据一致。
