摘　　要：采用电导仪连接记录仪,建立了一种测定水溶性高分子电解质溶解速度的精确方法——电导毫伏输出记谱法,测定偏差±5％。采用该方法,准确地表征了不同样品、不同粒度在不同温度下的溶解时间,从而考查了水溶性高分子电解质的溶解特征。A precision device based on the conductance millivolt input notation method, connecting an electrical conductometer to a recorder, and with a deviation of ±5％ is established for the determination of the rate of dissolution of water-soluble polymeric electrolyte. The dissolution time of different samples with different particle sizes and at different temperatures is accurately determined. Thus the dissolution characteristics of water-soluble polymeric electrolyte is investigated.
