| Abstract: | The paper summarized the development of the theory about the secondary emission.The theory mainly includes the studies about the relatively factors influencing the secondary emission and the studies about the secondary emission under the ion bombardment and the studies about the relationship between the secondary emission properties and the cover rate of oxygen on the metal surface.This paper summarized the secondary emission phenomena and presented the properties and practices of several types of valid and developed secondary emission material.Based on the development experience and the study fruit of the hot cathode composed of the rare earth and Mo,this paper advanced some speculations and assumes about the studies and the practice of the secondary emission about this kind of cathode. |
