Rheological measurements on a high molecular weight Hyaluronic Acid (from rooster combs) were performed to obtain information on the viscoelastic and temporary network characteristics of Hyaluronic Acid solutions as a function of the concentration. From rheological experiments, the critical concentration c* and the concentration dependency of the plateau modulus G degrees e were determined. Further on, structural parameters as Me, the average molecular weight of the polymer segments between entanglement points, and DN, the average distance between entanglement points, were estimated.
对一种高分子量透明质酸（来自公鸡鸡冠）进行了流变学测量，以获取关于透明质酸溶液的粘弹性和临时网络特性随浓度变化的信息。通过流变学实验，确定了临界浓度c*和平原模量G°e的浓度依赖性。此外，还估算了结构参数，如缠结节点之间聚合物链段的平均分子量Me以及缠结节点之间的平均距离DN。
