摘要：

Both　thermodynamic　calculation　and　experimental　observation　show　that　no　elemental　lanthanum　can　be　obtained　by　reduction　or　thermal　decomposition　at　high　temperature.　The　emission　mechanism　of　Mo-La2O3(Mo-La)　cathode　is　much　different　from　the　mono-atomic　layer　mechanism　of　Th-W　cathode.　A　new　emission　mechanism　of　Mo-La　cathode　has　been　put　forward,　which　can　reasonably　explain　the　emission　behavior　of　Mo-La2O3　cathode.
