摘要：

There have been several studies on sulfur depletion in dense cores like TMC-1(Taurus Molecular Cloud1), employing updated reaction networks for sulfur species to explain the missing sulfur in the gas within dense clouds. Most of these studies used a C/O ratio of 0.7 or lower. We present NSRT(NanShan 26m Radio Telescope)observations of TMC-1 alongside results from time-dependent chemical simulations using an updated chemical network. Our findings highlight the impact of the C/O ratio on the gas-phase evolution of C2S and C3S. The simulation results show that the C/O ratio is an important parameter, playing a fundamental role in determining the gas-phase abundances of sulfur species in dense cores.
