本文介绍了一种新的等离子体源--扩散共面面阻挡放电（DCSBD）。DCSBD允许在大气压空气中以超过100 W cm（-3）的高等离子体功率密度维持视觉上扩散的高密度“冷”等离子体，从而允许大面积幅材和平坦表面的高速表面处理。在450 m min（-1）和短至0.14 s的等离子体暴露下，薄聚丙烯织物成功在线活化的结果证明了这一点。DCSBD的基本特点，导致所观察到的高效率的等离子体激活和相关的等离子体化学机制进行了简要讨论。
A new plasma source, the so-called diffuse coplanar surface barrier discharge (DCSBD), is described. DCSBD allows a visually diffuse high-density 'cold' plasma to be sustained in atmospheric-pressure air at a high plasma power density exceeding 100 W cm(-3) that permits high-speed surface processing of large-area webs and flat surfaces. This is demonstrated by the results on a successful in-line activation of thin polypropylene fabric at 450 m min(-1) and plasma exposures as short as 0.14 s. DCSBD basic features resulting in the observed high efficiency of plasma activation and the related plasmachemical mechanism are discussed briefly.
