摘　　要：目的 :通过改变流动渠道平面层的厚度和红细胞压积来研究红细胞聚集体的形成时间与聚集体结构的相互关系。方法 :利用平面流动渠道系统用光学测量方法获取红细胞聚集曲线 ,并用倒置显微镜进行同步显微摄影。结果 :红细胞聚集体形成时间分别与聚集体的薄层厚度和红细胞压积呈线性相关 ,r分别为 0 .989、0 .990。结论 :采用各类方法研究红细胞的聚集过程时 ,由于所用研究设备的腔体尺寸和选用的血液压积不同 ,用聚集时间所表达的聚集指数没有类比性。Objective: To study the relation between of forming time red blood cell aggregation body and structure by changing the thickness of flow channel plane and red blood cell hematocrit. Methods: A system with flow channel technique and light transmission measurements were applied to gaining red blood cell aggregation curve. Results: The forming time of red blood cell aggregation body and the thickness of aggregation body as well as red blood cell hematocrit were linearily correlated with a correlation coefficient r of 0.989 and 0.990 respectively. Conclusion: When red blood cell aggregation process is studied using different methods, red blood cell aggregation time index can not be compared.
