摘要	The relationship bettween the existing form and inhibiting behavior of dolecylamine(DDA) on amorphous alloy has been studied by electrochemical measurement, physical test and scanning tunneling microscopy. The experiment shows that there is different relationship between the inhibition concentration and inhibition percentage in different concentration scale. In w(DDA)=10(-6) similar to 10(-4) concentration range, the inhibition percentage increased strongly with the inhibitor concentration but the increase tendency of inhibition percentage became gently in 10(-4) similar to 10(-3) concentration scale. The adsorption isotherm formula fitting result shows that a typical mono-molecular layer of DDA was adsorbed on amorphous alloy during 10(-6) similar to 10(-4) concentration scale, without any effect from the neighbor inhibitor molecule, but in 10(-4) similar to 10(-3) range the force between the nearing neighbor inhibitor molecule decided the adsorption form. The result from STM and conductivity test indicats that the micelle had been formed when the concentration approached w(DDA)=2.3x10(-5), the protection effect DDA was prevented because of the forming of micelle.
