With the PICR hydrodynamic model, we study the polarization splitting between$\Lambda$ and $\bar{\Lambda}$ at RHIC BES energy range, based on the mesonfield mechanism. Our results fit to the experimental data fairly well. Besides,two unexpected effect emerges: (1) the baryon density gradient has non-trivialand negative contribution to the polarization splitting; (2) for 7.7 GeV Au+Aucollisions within the centrality range of 20\%-50\%, the polarization splittingsurprisingly increases with the centrality decreases. The second effect mighthelp to explain the significant signal of polarization splitting measured inSTAR's Au+Au 7.7 Gev collisions.
