摘要：

We present the results from arcsecond resolution observations of various line transitions at 1.3 mm toward hypercompact H II region G28.20-0.04N. With the SMA data, we have detected and mapped the transitions in the CH 3CN, CO, (CO)-C-13, SO2, OCS, and CH 3 OH molecular lines as well as the radio recombination line H30 alpha. The observations and analysis indicate a hot core associated with G28.20-0.04N. The outflow and possible rotation are detected in this region.
