论文摘要
在此评论中，我们调查了Brans-Dicke标量字段$（ϕ）$带有比例因子$（a）$的功率法律变化未经一般的宇宙中的场外方程式验证，充满了暗物质和Tsallis型全息暗能量。但是，对于特定选择的自由参数，$（ω= - \ frac {3} {2} \; \; \; \; \; \; \; n = -1）$与Ghaffari等人在Ghaffari et al \ textColor {blue} {[Ghaffari等人中固定的值不同。欧元。物理。 J. c \ textbf {78}，706（2018）]}}}描述了宇宙的各种物理属性，以衍生模型，$ ϕ $的功率定律变化带有$ a $ a $ leds以符合一致的结果。此外，我们注意到Brans-Dicke Gravity中Tsallis全息暗能量的节能法不存在。
In this comment, we have investigated that the power law variation of Brans-Dicke scalar field $(ϕ)$ with scale factor $(a)$ is not validated by field equations in general for the Universe filled with dark matter and Tsallis type holographic dark energy. However, for specific choice of free parameters $(ω= -\frac{3}{2}\;\; \&\;\; n = -1)$ which are differ from its values fixed in Ghaffari et al \textcolor{blue}{[Ghaffari et al. Euro. Phys. J. C \textbf{78}, 706 (2018)]} to describe various physical properties of the Universe in derived model, the power law variation of $ϕ$ with $a$ leads to consistent results. Further, we notice that the energy conservation law for Tsallis holographic dark energy in Brans-Dicke gravity does not hold.
