| 摘 要： | 物质超细化后除产生强烈的量子尺寸效应和宏观量子遂道效应外,还将产生强烈的表面效应和体积效应等。这些效应可改变其的电化学性质。早在1982年Plieth1]就发现了金属颗粒的粒度对电极电势有影响,随后又在理论和实验方面做了许多工作2,3]。后来人们又不断发现,组成电极的粉末

| Abstract: | A kind of dispersed electrode was prepared by electrodeposition technique.The factors of affecting the electrodeposition were discussed and the electromotive force of the dispersion cell was measured this paper.The results shows that there are obvious effects of quantity of addictives,the current density and temperature on the dispersivity of the dispersed electrode,and that there indeed exists a potential difference between two electrodes of the same material with different dispersivity,namely the electromotive force of a dispersion cell.It was concluded that and the greater difference of the dispersivities between the two electrodes,the greater electromotive force of the dispersion cell. |
