摘　　要：本文详细介绍了一种红细胞聚集仪器的测量原理和系统结构。该仪器通过测量血液样品对激光的反向散射光强，得到反映红细胞聚集过程的动力学、结构和流变学指标。由PC机和8098单片机构成的系统实现仪器的自动控制、测量和数据存贮等功能。In this paper,an erythrocyte-aggregometer based on the analysis of the light intensity back-scattered by a blood suspension is presented and described in detail. It allows to approach aggregation phenomenon in terms of kinetics,structural and rheological parameters. A personal computer and a microcomputer are applied to automate the system's sampling,data- processing and data -restoring procedure.
