emission current [电] 发射电流
- Result shows hafnium carbide formed on the surface of CNT films at annealing temperature of1200℃, which improved the field emission current densities, emission uniformi
研究结果表明在适当的退火温度下碳纳米管表面形成了碳化铪,并显著提高了碳纳米管的发射电流密度、射均匀性和发射稳定性。 - We suggest that as lead-free cathode materials, BNBT and BT outweigh PZT from environmental consideration in spite of the fact that the field emission current density of PZT is slightly higher than
结果认为:锆钛酸铅材料的电子发射电流密度略优于其他两种材料,但从无铅化角度来讲,钛酸钡与钛酸铋钠材料将有望取代现有的锆钛酸铅铁电阴极材料。 - Test items:① Insertion loss;② Disturbance voltages;③ Radiated electromagnetic disturbances;④ Harmonic current( emission).
电磁兼容检验项目:①插入损耗;②骚扰电压;③辐射电磁骚扰;④谐波电流。
