摘要：

Glow discharge of a spherical geometry is used to produce and investigate dusty plasma structures. Production of dust in air plasma spontaneously occurs due to sputtering of cathode, and structures arise around an anode, but the structures of injected grains with short lifetime were observed in high molecular gases such as acetone and ethyl alcohol. Experiments were carried out in the gas pressure range of 30-100 Pa and discharge current range of 20-30 mA. To control the chemical composition of gas environment, mass spectrometry was used.
