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.充率小和酸分层导致蓄板底部处于欠充状态,加剧硫酸盐化。

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.本文主要用离子法与改良硫酸钡比浊法对大气硫酸盐化速率进行分析。
