We have come to the following conclusions:(1) the existence of the monoatomic layer is conditional, it depends upon the temperature, surface structure and purity of the substrate as well as upon the vacuum environment;(2) the appearance, and sometimes disappearance, of the emission peaks is a problem for further study, and it can not be explained simply by the monoatomic layer...

关于时而能、时而又不能观察到的电子发射峰值，是一个有待于进一步明确的现象，不能简单地用单原子层和偶极子理论来解释；3。吸附了外界原子或分子使电子发射增加的事实，并不是由于偶极矩降低了基底的逸出功，发射的电子来源于被吸附物质的价电子；4。实验证明&L&阴极是Ba-O-W系统，它既不是单原子层，也不是单分子层，也不适用偶极子理论。
