摘　　要：讨论了偶氮苯衍生物自组装膜的电极反应速率常数对其表面覆盖度的依赖关系的机理，建立了相应的数学模型，进一步编写计算程序对这种电化学行为做了模拟讨论。The characterishc elecbehemical mechanics of azobenzene derivative self-assembled monolayers is discussed in present paper.It is presented that the structure inhibition is one of the most important factors in the increase of electrochemical reactive energy.A corresponding mathematical model was established based on Levich and Marous's theory.Moreover,computational program was written to simulate the decrease of apparent rate constant (Ｋapp) of electron transfer with increasing surface concentration.
