N2 - Sulfur-bearing species are widely utilized to investigate the physical structure of star-forming regions in interstellar media; however, the underlying sulfur chemistry in these environments remains poorly understood. Therefore, further studies of S-bearing species are fundamentally important, as they can enhance our understanding of the physical evolution of star-forming regions. This study presents observations of C2S and C3S in L1544, acquired using the Nanshan 26-m radio telescope, along with simulations of their chemical behavior using a one-dimensional physical model. The simulation results reveal significant radial variations in the column densities of C2S and C3S. Additionally, the column densities of both molecules are found to be sensitive to the cosmic ray ionization rate at several radial positions, while variations in the C/O ratio have comparatively minimal impact on L1544.
