Fukui函数分析。为了进一步预测精氨酸分子在金属表面的反应位点，利用

Fukui function analysis. In order to predict the arginine molecule at the reaction site of the metal surface by Fukui index local reaction behavior was analyzed, Fukui index can be measured not only the strength and reactivity of the molecules, but also can determine the active electrophilic site, or nucleophilic properties [30-31]. In certain cases the applied potential field, the first derivative of the electron density index is defined as Fukui electron number N:

Fukui function analysis. In order to further predict the reaction site of arginine molecules on the metal surface, the local reaction behavior of the Fukui index was analyzed, and the Fukui index could not only determine the reaction activity and strength of the molecule, but also determine the pro-electric or pro-nuclear characteristics of the active sites. With an additional potential field, the Fukui index is defined as the first derivative of the electron density to the electron number N:

Fukui function analysis. In order to further predict the reaction site of arginine on the metal surface, the local reaction behavior is analyzed by using the Fukui index, which can not only determine the reaction activity and strength of the molecule, but also determine the electrophilic or nucleophilic properties of the active site [30-31]. When the external potential field is fixed, the Fukui index is defined as the first derivative of the electron density to the electron number n<br>
