1.Advances in vacuum arccathode spots真空电弧阴极斑点的研究进展
2.By using a Scanning Electron Microscope (SEM), the tracks ofcathode 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。
3.The tracks ofcathode spots produced after the first discharge on the surfaces of nanostructured and conventional W-Cu cathodes were investigated using a scanning electron microscope (SEM), and the influence of microstructure of composites on the morphology and movement ofcathode spots was studied.采用扫描电子显微镜观察了W-Cu复合电弧阴极材料首击穿后的表面形貌,研究了复合阴极材料微观结构对阴极烧蚀形貌和阴极斑点运动的影响。
3)cathode-ray spot阴极挥点，阴极斑点
4)cathode spot阴极斑点，阴极弧光，阴极炽点
5)vacuum arc cathode spot真空电弧阴极斑点
6)anode spot阳极斑点
1.The critical current ofanode spots formation within short gaps is lower than that within long gaps.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 。
