摘要We performed a multiwavelength study toward the infrared dark cloud (IRDC) G34.43+0.24. New maps of Co-13 J = 1-0 and (CO)-O-18 J = 1-0 were obtained from the Purple Mountain Observatory (PMO) 13.7 m radio telescope. At 8 mu m (Spitzer-IRAC), IRDC G34.43+0.24 appears to be a dark filament extended by 18' along the north south direction. Based on the association with the 870 pm and (CO)-O-18 J = 1-0 emission, we suggest that IRDC G34.43+0.24 should not be 18' in length, but extend to 34'. IRDC G34.43+0.24 contains some massive protostars, UC H II regions, and infrared bubbles. The spatial extend of IRDC G34.43+0.24 is about 37 pc, assuming a distance of 3.7 kpc. IRDC G34.43+0.24 has a linear mass density of similar to 1.6 x 10(3) M-circle dot pc 1, which is roughly consistent with its critical mass to length ratio. The turbulent motion may help stabilize the filament against the radial collapse. Both infrared bubbles N61 and N62 show a ringlike structure at 8 itm. In particular, N61 has a double-shell structure that has expanded into IRDC G34.43+0.24. The outer shell is traced by 8 pm and (CO)-C-13 J = 1-0 emission, while the inner shell is traced by 24 itm and 20 cm emission. We suggest that the outer shell (9.9 x 10(5) years) is created by the expansion of H II region G34.172+0.175, while the inner shell (4.1 similar to 6.3 x 10(5) years) may be produced by the energetic stellar wind of its central massive star. From the GLIMPSE I catalog, we selected some Class I sources with an age of 105 years. These Class I sources are clustered along the filamentary molecular cloud.
