| 英文摘要 | Here we present the study on chemical properties of massive star forming clumps using N2H+(1-0), (HCO+)-C-13(1-0), HCN(1-0) and (HNC)-C-13(1-0) data from the literature [Astron. Astrophys. 563, A97 (2014)]. We found that abundances of (HCO+)-C-13 and (HNC)-C-13 are affected by H-2 column densities. As the median values of these two abundances increase by nearly 10 times from stages A to B, (HCO+)-C-13 and (HNC)-C-13 are suitable for tracing the evolution of massive star forming clumps. The order of rapidity in growth of abundances of all the four studied molecules from stages A to B, is (HCO+)-C-13, HCN, (HNC)-C-13, and N2H+, from the highest to the lowest. Our results suggest that the observing optically thin molecular lines with high angular resolution are necessary to study the chemical evolution of massive star forming clumps. |
