Many bipolar flow sources have been found around infrared sources with a wide luminosity range. The bipolar sources are thought to be a common stage of early stellar evolution. Recently, compact dense molecular clouds have been detected, just around the exciting infrared sources of several bipolar flow sources (e.g. Torrelles et al. 1983). An investigation of the nature of these surrounding dense molecular clouds should be important to study the acceleration and collimation mechanisms of the bipolar outflow.
