英文摘要

Using the Purple Mountain Observatory Delingha (PMODLH) 13.7m telescope, we report a 96 deg(2) (CO)-C-12/(CO)-C-13/(CO)-O-18 mapping observation toward the Galactic region of l = [139 degrees. 75,149 degrees. 75], b = [-5 degrees. 25, 5 degrees. 25]. The molecular structures of the Local Arm and Perseus Arm are presented. Combining H I data and part of the Outer Arm results, we obtain that the warp structure of both atomic and molecular gas is obvious, while the flare structure only exists in atomic gas in this observing region. In addition, five filamentary giant molecular clouds on the Perseus Arm are identified. Among them, four are newly identified. Their relations with the Milky Way large-scale structure are discussed.
