通过对各种材料(铜、铝、锡)组成的电极间电传导的研究,已收集到一些在预击穿过程中材料转移和表面演变方面的资料。本文实验范围已扩展到钦电极对和钦与铜或不锈钢组成的电极对。本文的目的是研究预放电电流,并对电极进行光学观察和表面分析,从而弄清楚表面演变和金属转移问题。实验是在文献[1]中已描述过的真空容器里真空度为10~(-6)～10~(-7)乇的条件下进行的。电
Through the study of the electrical conduction between electrodes composed of various materials (copper, aluminum, tin), some data on the material transfer and surface evolution during the pre-breakdown process have been collected. The experimental scope of this paper has been extended to the pairs of electrodes and the pairs of electrodes made of copper and stainless steel. The purpose of this paper is to study the pre-discharge current, and to optically and surface-analyze the electrode to clarify the surface evolution and metal transfer problems. The experiment was carried out under the conditions of a vacuum degree of 10 -6 to 10 -7 Torr in a vacuum vessel as described in Reference [1]. Electricity
