报告人简介：Professor Yuri S. Akishev is a distinguished physicist and Head of the Plasma Physics Laboratory at the State Research Centre of the Russian Federation—Troitsk Institute for Innovation and Fusion Research (TRINITI).Professor Akishev’s research group has developed innovative gas-discharge systems for airflow control, gas purification, surface modification, and plasma sterilization. His studies on streamer dynamics and ionization instabilities under magnetic fields have deepened understanding of plasma behavior in applied and fundamental contexts. His recent works emphasize the synergistic use of experimental diagnostics and numerical modeling to explore plasma-assisted chemical and biomedical processes. As an influential figure in applied plasma science, he has authored numerous papers and supervised multiple international collaborations promoting the application of non-equilibrium plasma in environmental and industrial systems.

尤里·谢苗诺维奇·阿基谢夫（Yuri S. Akishev）教授是俄罗斯联邦国家科研中心托里茨克创新与聚变研究所（TRINITI）等离子体物理实验室主任、著名等离子体物理学家。阿基谢夫教授团队在扩散与收缩放电、介质阻挡放电（DBD）及等离子体表面相互作用等方面开展了系统研究，研制了多种用于气流控制、废气净化、表面改性与低温灭菌的放电装置。他在磁场作用下流注放电动力学与电离不稳定性机理研究中取得重要成果，为揭示复杂放电体系的演化规律提供了理论支撑。近年来，其研究聚焦于实验诊断与数值模拟结合的多物理场耦合机制，推动非平衡等离子体在环境治理与生物医学领域的工程化应用。

报告内容：在报告中，将综述纵向与横向磁场对体积放电及介质表面放电中流注传播特性的影响的最新研究进展，并展示该领域的实验与数值模拟研究结果。同时，还将讨论气体成分在磁场作用下对流注行为的影响机制。
