The internet address of the above Journal is as follows: http://www.sccj.net/A program written in JAVA language was developed for the virtual electrochemical measurement of a　modified electrode with a finite diffusion thickness, e.g., an electrode coated with polymer film in which　functional molecules were dispersed. This program, called ES-2, can simulate cyclic voltammetry and　potential-step chronoamperospectrometry by considering the rate of charge injection from the electrode to　the functional molecule and the diffusion of charge. The results are shown by a voltammogram (I-V　curve),　and concentration distribution in the layer at a series of voltages at cyclic voltammogram mode, I-t curve,　and time dependence of concentration distribution in the layer at potential step mode and a text of current　values, the fraction of the oxidized molecules (RCT ) and parameters used for the simulation in both modes.　A dynamic textbook of electrochemistry can be constructed by this program combined with HTML text.
