摘要
IN the study of antigen and antibody reaction with ellipsometric spectroscopy, most researchers calculated the thickness of antibody film, absorbance and film constant by mathematic models.But by using simple mathematic models, it is very hard to describe accurately the real state of the system. Huang and Ord proposed a new physical measurement (optical tracking rate,V<sub>op</sub>), indicating the total change of △, Ψ in study of oxidation and reduction reaction of the iron electrode in alkaline solution. Many experimental results showed that the spectral peaks in V<sub>op</sub>～t figure correspond to the turning points on the polarization curve. This work
