In the present paper, we search the existence of dark energy scalar field models within in $f(R,T)$ gravity theory established by Harko et al. (Phys. Rev. D 84, 024020, 2011) in a flat FRW universe. The correspondence between scalar field models has been examined by employing the new generalized dynamical cosmological term $\Lambda \left(t\right)$. In this regard, the best fit observational values of parameters from three distinct sets of data are applied. To decide the solution to field equations, a scale factor $a={\left(sinh\left(\beta t\right)\right)}^{1/n}$ has been considered, where $\beta \&n$ are constants. Here, we employ the recent ensues ($H_0=69.2$ and $q_0=-0.52$) from (OHD+JLA) observation (Yu et al. (2018)). Through the numerical estimation and graphical assessing of various cosmological parameters, it has been experienced that findings are comparable with kinematics and physical properties of the universe and compatible with recent cosmological ensues. The dynamics and potentials of scalar fields are clarified in the FRW scenario in the present model. Potentials reconstruction is highly reasonable and shows a periodic establishment and in agreement with the latest observations.

在本文中，我们寻找暗能量标量场模型在 $F(\mathrm{电阻},吨)$Harko 等人建立的引力理论。(Phys. Rev. D 84, 024020, 2011) 在平坦的 FRW 宇宙中。使用新的广义动力学宇宙学术语检查了标量场模型之间的对应关系$\Lambda \left(吨\right)$. 在这方面，应用了来自三个不同数据集的参数的最佳拟合观测值。为了确定场方程的解，比例因子$\mathrm{一种}={\left(信\left(\beta 吨\right)\right)}^{1/n}$ 已经考虑，其中 $\beta \&n$是常数。在这里，我们使用最近发生的（$H_0=69.2$ 和 $q_0=-0.52$) 来自 (OHD+JLA) 观察（Yu 等人（2018））。通过对各种宇宙学参数的数值估计和图形评估，人们体验到，这些发现与宇宙的运动学和物理特性具有可比性，并与最近的宇宙学相兼容。在本模型的 FRW 情景中，标量场的动力学和潜力得到了阐明。电位重建是高度合理的，显示出周期性建立并与最新观察结果一致。
