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。
This article describes in detail the measurement principle and system structure of a red cell aggregation instrument. The instrument measures the backscattered light intensity of the laser light from the blood sample and provides the kinetics, structure and rheology parameters that reflect the process of erythrocyte aggregation. The system consisting of PC and 8098 microcontroller realizes the functions of automatic control, measurement and data storage of the instrument.
