Outside Front Cover: Surface microdischarge has shown great potential in practical applications. In our work, the effects of macroscopic parameters on the temporal evolution of OH radicals are investigatedin both plasma layer and afterglow region. The results reveal that OH lifetime dependence on the power is more pronounced compared to the modulation time, and the density decay is mainly ascribed to the transport process and recombination reactions of OH with itself.

外部封面：表面微放电在实际应用中显示出巨大潜力。在我们的工作中，在等离子体层和余辉区都研究了宏观参数对OH自由基时间演化的影响。结果表明，与调制时间相比，OH寿命对功率的依赖性更加明显，并且密度衰减主要归因于OH与自身的迁移过程和重组反应。
