So the oxidation of diethyl stilbestrol was that two phenolic hydroxyl groups were oxidated to carbonyl group by two electrons and two protons process.

所以己烯雌酚的氧化过程为两个酚羟基经过2质子2电子反应被氧化成羰基。

The oxidation of diethyl stilbestrol was dependent on adsorption controlling process at MWNT /graphit modified electrode. The transmitted electron number, 2, was calculated by LAVIRON formula. By the linear relationship of peak potential and pH, it can be inferred that the transmitted number of electron and proton were equal.

己烯雌酚在MWNT/石墨修饰电极上的氧化过程靠吸附控制；由峰电位Ep与溶液pH存在的线性关系求出参与电极反应的质子数与电子数相等，由LAVIRON公式求解出参与电极反应的电子数为2。
