用动态光散射技术跟踪了海藻酸钠水溶液在０．１ｍｏｌ／ＬＣａＣｌ２水溶液中透析凝胶化的过程。表现出随反应进行，平均衰减速率（线宽）Γ明显减慢及以ｌｇβ１／２ｇ（１）（τ）对τ作图表明体系运动模式复杂的特点，这里ｇ（１）（τ）和τ分别是归一化电场时间相关函数及延迟时间。最后还以平均特征松弛时间τｃ（≡Γ－１）对透析时间ｔ作图，定量描述了该凝胶化反应的动力学过程。
The dynamic light scattering technique was used to trace the dialysis gelation of sodium alginate solution in 0.1 mol / L aqueous solution of LCaCl2. Showed that the average decay rate (line width) Γ significantly slowed down and the complex kinematic model was characterized by 1gβ1 / 2g (1) (τ) versus τ where g (1) (τ) and τ Respectively, normalized electric field time correlation function and delay time. Finally, the average characteristic relaxation time τc (≡Γ-1) on the dialysis time t mapping, quantitative description of the gelation reaction kinetics.
