1.The low charging rate in conjunction with acid stratification cause a significant undercharging of the low part of the electrodes,which again causes accelerated sulphation.

1.充电率小和分层导致蓄电池极板底部处于欠充状,化。

2.In this paper,two methods for analyzing air sulphation rate were studied and compared.One was ion chromatography and the other was barium sulfate spectrophotometry.

2.本文主要用离子色谱法与改良钡比浊法对大气化速率进行分析。
