实验研究了介质阻挡微等离子体在大气中的动态力诱导。由于微米级(25微米)的间隙，在大气中只有−1.4KV产生微等离子体。通过发射光谱测量来确定微等离子体的特征。观察到了N_2秒正离子系统(SPS)的发光。微等离子体的N2SPS发射信号寿命约为50 ns。将直径为50µm的SiO_2玻璃微珠分布在电极表面，观察微等离子体产生的动态力。用波长为532 nm的NdYVO4激光器和高速摄像机观察了玻璃微珠的运动。当微等离子体电极在−1.4KV下通电时，玻璃微珠移动。对获得的照片数据的分析表明，玻璃微珠以1 mm/ms的速度上升到微等离子体电极上方5 mm。
Kinetic force induction using dielectric barrier microplasma at atmospheric was experimentally investigated in this study. Owing to a micrometer-scale (25 µm) gap, microplasma was generated at only −1.4 kV in atmospheric air. Emission spectrum measurements were determine to identify the microplasma characteristics. Light emission of the N2 second positive system (SPS) was observed. The lifetime of emission signals for the N2 SPS for the microplasma was about 50 ns. SiO2 glass beads of 50 µm diameter were distributed on the surface of an electrode to observe the kinetic force generated by microplasma. Glass bead movements were observed using the Nd; YVO4 laser of 532 nm wavelength and a high-speed camera. When the microplasma electrodes were energized at −1.4 kV, the glass beads moved. Analysis of the obtained photo data showed that the glass beads rose to 5 mm above the microplasma electrodes at a velocity of 1 mm/ms.
