非热平衡常压等离子体射流（APPJ）是一种有望实现各种创新应用的冷等离子体源，而均匀的APPJ更受青睐。辉光放电是获得均匀放电的最有效方法之一。与大气压下的辉光介质阻挡放电（DBD）相比，纯氦APPJ同时表现出辉光放电和流光的部分特征。本文考虑潘宁效应的影响，对He APPJ和Ar/NH3 APPJ的电学和光学性质进行了研究。用“类辉光APPJ”一词来表征APPJ的均匀性，得到类辉光APPJ的基本特性是由kHz交流高压驱动的。研究结果可为统一APPJ的生成提供支持，为其应用奠定基础。
Non-thermal equilibrium atmospheric pressure plasma jet (APPJ) is a cold plasma source that promises various innovative applications, and the uniform APPJ is more favored. Glow discharge is one of the most effective methods to obtain the uniform discharge. Compared with the glow dielectric barrier discharge (DBD) in atmospheric pressure, pure helium APPJ shows partial characteristics of both the glow discharge and the streamer. In this paper, considering the influence of the Penning effect, the electrical and optical properties of He APPJ and Ar/NH3 APPJ were researched. A word "Glow-like APPJ" is used to characterize the uniformity of APPJ, and it was obtained that the basic characteristics of the glow-like APPJ are driven by the kHz AC high voltage. The results can provide a support for generating uniform APPJ, and lay a foundation for its applications.
