作为高电压技术的最新应用方向之一，大气放电产生等离子体降雨技术已经在大气水资源综合利用方面取得了重大突破。为了进一步研究大气放电产生等离子体降雨技术的相关内容和特性，系统分析和比较了大气放电等离子体降雨技术和激光等离子体降雨技术的特性，并通过流体模型计算分析了驱动电源的工作频率对等离子体中促进降水产生关键离子O2-产量的影响。结果表明：大气放电等离子体降雨技术的带电粒子产量是激光催化降雨技术产量的10^5倍，所以认为大气放电等离子体技术拥有更高促进降雨发生的概率；通过不同频率下放电稳定工作模式和O2-产量对比确定了驱动电源的最佳工作频率在100～1000MHz。

As one of the latest application areas of high voltage technology, artificial rain induced by air discharge plasma has made a great breakthrough in the aspect of atmospheric water resources comprehensive utilization. For further studying the related issues and the characteristics of the rain technology, the characteristics of air discharge plasma and laser plasma for artificial rain technologies are analyzed and compared, and the effect of the power supply frequency on the production of O2- , which plays a key role in promoting the production of artificial rain, is analyzed numerically through a fluid model. The result shows that the charged particles generated by air discharge plasma are 10^5times more than those by laser plasma, indicating that air discharge plasma is more efficient for producing artificial rain. Through comparison of discharge working modes under different frequencies and the number of O2- production, the best working frequency of the power supply is found to be among 100~1 000 MHz. Furthermore, an experiment of cloud and mist production by means of plasma catalytic is successfully performed in an artificial circumstance chamber.
