摘　　要：主要讨论了海水组成的变化对海水直接电解过程的影响。海水的组成随季节、地点的变化而变化。当海水中氯离子浓度下降时,阳极的电极电位上升,同时电解过程的电流效率下降。当海水中钙镁离子浓度增加时,电流效率上升。The influences of the composition of seawater to the seawater direct electrolysis were discussed. The composition of seawater varies from season to season and from place to place. While the concentration of Cl^- decreases, the electrochemical potential in creases and the current efficiency decreases. The current efficiency increases progressively as the concentration of Mg^(2+) (or Ca^(2+)) concentration does.
