title: [Spectral diagnosis of dielectric barrier plasma discharge at atmospheric pressure and its application to surface modification of materials].
abstract: The spectral lines of air and argon plasma emission at atmospheric pressure were recorded and analyzed. Plasma parameters such as discharge current, discharge gap and electron temperature were measured. The purpose of the study is to control the process of materials' surface modification promptly. The experimental results indicate that a critical discharge gap is an important parameter to improve the quality of materials' surface modification, and spectral diagnosis has been proved to be a workable method by choosing a suitable discharge gap.
