The equivalent circuit was built. The following results are concluded: (1) The electrochemical reduction process of Bup on the glassy carbon electrode is involving charge transfer, strong adsorption of electroactive species, and particulate pervasion.

• 结果发现Bup在玻碳电极上的电还原可能涉及的基本过程是:电荷传递反应过程、电活性质粒的吸附过程以及反应质粒的扩散过程,并建立了相应的等效电路图。
