The density of state of valence electron of La and O ions increase during activation processes. The 6s higher energy valence electrons of La ions with unsaturated coordination number is easy to emit. It is clear that the processes is beneficial to thermionic emission.

激活过程促使La，O离子的价电子态密度增加，配位不饱和的La离子外层6s高能价电子易形成电子发射，即这一变化过程对热电子发射具有积极作用。
