“cathode”的概念、定义、习题解题方法及翻译-物理辞典

单词	cathode
释义	cathode A negative electrode. In electrolysis cations are attracted to the cathode. In vacuum electronic devices electrons are emitted by the cathode and flow to the anode.

However, in a primary or secondary cell the cathode is the electrode that spontaneously becomes negative during discharge, and from which therefore electrons emerge
