摘要：
The formation and evolution of the Milky Way bulge can be constrained by studying elemental abundances of bulge stars. Due to the large and variable visual extinction hi the line-of-sight towards the bulge, all analysis in the near-IR is preferred. Here, I will present some preliminary results of in on-going project in which elemental abundances, especially those of the C, N, and O elements, of bulge stars are investigated by analysing CRIRES spectra observed with the VLT.
