The influence of electrode construction on life time of small power high pressure sodium lamp are emphatically studied.
着重研究了灯电极结构对寿命的影响。
It was concluded that high internal pressure was caused by oxygen evolution of positive electrode and slow reducing rate of oxygen in negative electrode.
由此可以判定，内压升高的原因在于正极的析氧及负极氧还原速度的缓慢。
