摘　　要：本文介绍了对酸性示波中和指示剂刚果红、百里酚兰和对、间。The present paper covers the mechanism about the formation of the incision in Oscillopolarograms with Congo red, Thymol blue, and Nitrophenols as Oscillopolarographic neutralization indicators. The incisions of Azo compuonds, Sulfanaphthaleins and Phenelphthalein are due to oxido reduction and that of Nitrophenols are due to adsorption of the indicators at the polarized electrode.
