介绍一种新的测量红细胞沉降速度的系统装置和方法，通过连续记录沉降样品室中血样透射光的强度值，获得沉降速度曲线及其特征参数．利用不同分子质量的葡聚糖（Ｄｅｘｔｒａｎ）Ｄｘ－５０，Ｄｘ－１００，Ｄｘ－２００来改变红细胞的聚集性，特征参数ｖｍａｘ和ｔｍａｘ随之发生相应的变化，且各组之间差异显著（Ｐ＜０．０５），表明该两参数能够反映沉降过程中红细胞流变学性质特别是聚集性的变化 A new system and method for measuring erythrocyte sedimentation velocity were introduced. The sedimentation velocity curve and its characteristic parameters were obtained by continuously recording the intensity of the transmitted light in the sample chamber. Using different molecular weight of Dextran Dx-50, Dx-100, Dx-200 to change the aggregation of erythrocytes characteristic parameters vmax and tmax corresponding changes, and the significant difference between the groups (P <0.05), indicating that these two parameters can reflect the change of erythrocyte rheology, especially aggregation, during sedimentation
