摘要：

The structure and stability of plasma jet were studied on the basis of statistical analysis of the images of the jet taken by a fast shutter camera. The space distribution of the mean value and the standard deviation of image brightness were evaluated from a sequence of images. The short exposure time ensures imaging of the momentary state of the jet while analysis of sequence of images provided information on jet fluctuations. The effects of are current and anode position on thermal plasma jet were investigated. Are power increase led to higher fluctuations of the jet, it although causes increase of the jet length.
