Compared to traditional methods

the high effi-ciency

innocuity

and energy-saving recommends the plasma processing for surface treatment and sterilization applications.The"classical"atmospheric pressure discharges such as corona discharges

dielectric barrier discharges and arc dis-charges each have drawbacks that make them unsuitable for above applications.However

there are some obstacles in ob-taining atmospheric pressure glow discharge plasmas although the technology of low-pressure glow discharge plasmas has been most highly developed.At present

investigation of physical processes in the atmospheric pressure glow discharge is focusing on the physical mechanism

image capture

and realization of the glow discharges in atmospheric pressure air.
