| 摘 要： | 详细讨论了石英管对平行WR-430波导谐振腔内部电场强度的影响。在没有石英管时，电场强度在每个狭缝附近发生突变，其峰值沿着一个波导逐渐减小，而沿着另外一个波导逐渐增大。存在石英管时，内部电场变弱且沿着石英管内表面无规则振荡，而且电场沿着两个波导之间的中心轴线波动。当石英管壁厚度和离上下波导的距离分别为5和2 mm时，谐振腔内部的平均电场强度达到最大，而且电场强区面积较大。当上述两者分别超过5和2 mm时，内部电场的最大值会随着石英管壁厚度和距离逐渐减弱。低气压和大气压空气等离子体在谐振腔内部被激发，其形态比较接近各自的仿真的电场强度分布。

| Abstract: | The influence of quartz tube on the electric field intensity in the parallel WR-430 waveguide resonant cavity is discussed. The electric field intensity has an abrupt change like a positive impulse near every slot and the impulse peak increases along the surface of one waveguide while decreases along the surface of the other when there is no quartz tube. In the presence of quartz tube, the electric field intensity gets weaker and fluctuates more irregularly along the wall of quartz tube. Noteworthily, it waves along the axis of the plasma generation zone in these two cases. While the wall thickness of quartz tube is 5 mm and the distance of quartz tube from waveguides is 2 mm, the average electric field intensity reaches maximum and the high electric field area is comparatively large. The maximum electric field intensity decreases with the increase of the wall thickness and distance for their values respectively greater than 5 and 2 mm. Low-pressure (1 500 Pa) and atmospheric air microwave plasmas are produced and their appearances are much similar to corresponding side-distributions of electric field intensity. |
