在不同的温度、压力和电压条件下，对开发出来的阴极材料进行了电发射特性的试验研究研究结果表明，温度、压力及电压对发射电流均有显著的影响，在高温（ ＞ ８００ ℃） 条件下，由阴极材料热发射所获得的电流密度，比通过电晕方式所得到的电流密度至少高一个数量级阴极板具有良好的稳定性，可在高温高压下长期使用
Experimental studies on the characteristics of the electron emission of the developed cathode material under different temperature, pressure and voltage conditions have shown that the temperature, pressure and voltage have a significant effect on the emission current at high temperatures (> 800 °C Under the conditions, the current density obtained by the thermal emission of the cathode material is at least one order higher than the current density obtained by the corona method. The cathode plate has good stability and can be used under high temperature and high pressure for a long time.
