摘　　要：基于介质阻挡放电原理,该文工作搭建了一种悬浮式电极的低温等离子体装置,并开展了细菌灭活的实验。实验结果表明,该装置对金黄色葡萄球菌和大肠杆菌具有显著的灭活效果:作用时间30 s内金黄色葡萄球菌和大肠杆菌灭活效率达到99.99%以上;作用距离对灭菌效果具有明显影响作用,其中作用距离为1 mm时的灭菌效果最佳。In this work, a floating-electrode dielectric barrier discharge plasma device was constructed based on the principle of dielectric barrier discharge, and its application of bacterial inactivation was studied. The experimental results show that the device has a significant sterilization performance in the inactivation of Staphylococcus aureus and Escherichia coli. The inactivation efficiency of Staphylococcus aureus and Escherichia coli is more than 99.99% within 30 s. Treatment gap distance also plays an important role in sterilization and the best distance is 1 mm.
