摘要：
In this paper we describe the results of the first optical kinematic study of the planetary nebula BD+30 degrees 3639, This system has a central star of the Wolf-Rayet type and is believed to be fairly young. Emission-line spectra were obtained at high spectral and spatial resolution using the Utrecht echelle spectrometer at the William Herschel Telescope. These spectra indicate that the main ionized shell of BD + 30 degrees 3639 appears to be evolving in a more complex way than previously thought.
