The short circuit current calculation shows the rated thermal stability current of former current mutual inductor is too small.

通过计算短路点的短路电流，说明原电流互感器额定热稳定电流太小。

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。

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。
