In this paper, in an extended theory of gravity, we have presented bouncing cosmological model at the backdrop of an isotropic, homogeneous space-time, in the presence of general relativistic hydrodynamics (GRH). The scale factor has been chosen in such a manner that with appropriate normalization, the quintom bouncing scenario can be assessed. Accordingly, the bounce occurs at $t=0$ and the corresponding Hubble parameter vanishes at the bounce epoch. The equation of state (EoS) parameter and the energy conditions of the model have been analyzed. The violation of strong energy condition further supports the behavior of extended gravity. As the bouncing cosmology suffers with instability, this model also shows the similar behavior.

在本文中，在广义相对论流体动力学（GRH）的存在下，我们在广义相对论流体动力学（GRH）的存在下，在各向同性、均匀时空的背景下提出了弹跳宇宙学模型。比例因子的选择方式使得通过适当的标准化，可以评估 quintom 弹跳场景。因此，反弹发生在$吨=0$并且相应的哈勃参数在反弹时期消失。对状态方程（EoS）参数和模型的能量条件进行了分析。强能量条件的违反进一步支持了扩展重力的行为。由于弹跳宇宙学存在不稳定性，该模型也显示出类似的行为。
