Our experiments showed that it can ensure the same stability of thermal emission current by use of a new method of corroding cathode point.
实验表明，采用新方法对阴极尖端进行腐蚀后得到的尖端阴极，同样可保证热发射束流的稳定性要求。
Field emission stability and life time of CNT cathode is closely related with the vacuum level, thermal effects during the emission and the current transport capability.
影响碳纳米管阴极场发射稳定性和寿命的主要因素有真空度、场发射过程中的热效应以及场发射体对场发射电流的承载能力等。
