摘　　要：为了选用具有优良流动性的钨粉 ,我们采用日本MT 10 0 0多功能型粉体物性测定仪研究电子发射材料粉体物性指数 ,并且给出该材料的流动性评价。这有助于我们在生产阴极时 ,选用具有优良流动性的钨粉 ,从而进一步稳定阴极生产工艺。In order to choose the tungsten powder with the excellent flow properties, we studied the powder physical indexes of the electronic emitting material by Japanese MT-1000 multimeter, and the results indicated the evaluation of the flow properties of these powders. It helps us to choose excellent powder in the manufacture of the cathode, and thereafter, to stable the manufacture.
