摘　　要：通过实验分析,验证了浸铯的钽阴极在低于700℃时也有比较理想的发射,并有发射峰出现。同时对产生这种现象的原因进行了分析 与探索。This paper proves the discovery that tantalum(Ta) cathode which is mixed with cesium(Cs) has a ideal emission under 700℃., and there are several emitting-peaks during the procession of emission. For the significative phenomenon, we analyse the cause for it and make a careful search farther.
