摘要: 指出在磁控法测量热发射电子速率分布实验中,结果应为电子径向速率的分布,并证明电子的径向速率符合麦克斯韦速率分布率.

关键词: 热电子发射, 磁控管, 速率分布率

Abstract: It is pointed out that the result should be distribution of radial velocity in the experiment of the velocity distribution of thermionic electrons with magnetron. It is proved that the radial velocity distribution of thermionic electrons accords with the Maxwell velocity distribution.

Key words: thermionic electron emission, magnetron, velocity distribution
