The measurements of erythrocyte orientation, obtained through a spin labeling technique, are compared with a phenomenological model. Several rheological conditions are varied: hematocrit, suspending medium viscosity, blood age, artificial reversible aggregation. We found that the onset of orientation is very sensitive to any variation of these conditions, and that its measurement would be a good method to assess erythrocyte deformability. A critical shear rate for the orientation process is then determined and compared to the corresponding parameter obtained from viscosity measurements of identical suspensions. A close qualitative relationship is found between the two sets of values of the critical shear rate.
通过自旋标记技术获得的红细胞取向测量结果与一个唯象模型进行了比较。改变了几种流变条件：血细胞比容、悬浮介质粘度、血液保存时间、人工可逆聚集。我们发现取向的起始对这些条件的任何变化都非常敏感，并且其测量将是评估红细胞变形性的一种好方法。然后确定了取向过程的临界剪切速率，并将其与从相同悬浮液的粘度测量中获得的相应参数进行比较。发现两组临界剪切速率值之间存在密切的定性关系。
