通过测定海藻酸钠水溶液的特性粘数及在低高于强度的条件下其浓度与比浓粘度关系曲线上的峰值，系统地研究了KCl浓度在2×10（－5）－0.5mol·L（-1）范围内对海藻酸钠溶液粘度行为的影响．根据Odijk－Skolnick－Fixman理论和Rinaudo的处理方法，从理论上对海藻酸钠溶液的粘度行为进行了探讨．研究结果表明：聚电解质溶液的电粘滞效应可使用静电相关长度得到合理解释
By measuring the intrinsic viscosity of sodium alginate aqueous solution and the peak value of its concentration versus reduced viscosity under the condition of lower than high strength, the effects of KCl concentration at 2 × 10 (-5) -0.5 mol·L (-1) on the viscosity behavior of sodium alginate solution. According to Odijk-Skolnick-Fixman theory and Rinaudo’s treatment, the viscosity behavior of sodium alginate solution is theoretically studied. The results show that the electrical viscosity effect of polyelectrolyte solution can be reasonably explained by the length of electrostatic correlation
