By using a Scanning Electron Microscope (SEM), the tracks of cathode spots on the surface of nanocrystalline Cu cathode produced after the first discharge with peak current of 10 A was investigated.
采用扫描电子显微镜(SEM)观察了纳米Cu阴极在峰值电流为10A的小击穿电流下首击穿后的阴极表面烧蚀形貌,发现纳米Cu的阴极斑点从产生到熄灭期间的运动(即短程运动)并不是随机的,而是有一定取向的;进一步通过和常规Cu首击穿烧蚀形貌对比,分析了产生有向运动的原因。

初步发现在短间隙条件下 ,平板触头间隙中真空电弧形成阳极斑点的临界电流小于长间隙中的临界电流 ;从电流开断性能来讲 ,纵磁触头的优越性在短间隙条件下体现得尤为明显 。
补充资料：北极光
在北极地区，天空经常被绚丽的绿色、紫色和金色反射光照亮。这些就是北方的极光(北极光)。尽管在英语中“极光”有“黎明之光”的含义，但这些异常的光现象不是由于黎明引起，而是因为大气层受到太阳发射出的带电粒子的冲击而引起大规模放电所造成的。
