Abstract: Based on the academic presentations at conferences and recent research trends in the field of high voltage discharge plasma, the research status and development trends of high voltage discharge plasma are summarized and analyzed from the perspectives of characteristic mechanism research and application research. In terms of characteristic mechanism research, the focus is mainly on plasma excitation sources and their characteristics, plasma diagnostics, and plasma numerical simulations. Application research mainly concentrates on material modification, energy conversion, environmental governance, biomedical applications, and aerospace. Based on the content of conferences, significant progress has been made in the research of high voltage discharge plasma in China, and there is a mutual penetration and collaborative development between characteristic mechanism research and application research. In future research, it is necessary to focus on key scientific issues that are common to the field, such as addressing space-time multiscale problems, plasma dose characteristics, fine control techniques for plasma parameters, and the development of uniform and stable discharge generation techniques for different working media. Simultaneously, targeted efforts should be made to address key scientific issues related to high voltage discharge plasma and conduct focused research on specific applications in various domains, with the aim of establishing plasma processing technologies that are applicable in practical settings. As the connection between high voltage discharge plasma technology and other research fields becomes increasingly close, it is believed that there will be a continuous emergence of outstanding scientific research achievements at a higher level.
