摘　　要：血液是典型的生物流体,具有磁性和导电性,其电磁特性是利用电磁场对血液流动进行干预和控制的关键因素。本文在详细阐述血液的等效电路模型、电导率、复阻抗、磁化率等典型电磁参数的计算公式以及电磁场对血液作用机理的基础上,详细介绍了有关血液电磁特性的研究进展,包括血液电磁特性的量化及影响因素、电磁场中血液的受力分析等。本文将为建立精确的血液流动模型提供一定的理论依据。Blood is a characteristic biological fluid which behaves as a magnetic fluid due to the complex interaction of the intercellular protein, cell membrane and the hemoglobin, and exhibits considerably high static electric conductivity which is hematoerit and temperature dependent. Its electric and magnetic properties are the key factors for controlling blood flow in electromagnetic fields. This paper introduces the electric model of whole blood impedance, formula for whole blood＇ s electric conductivity, impedance and magnetic susceptibility, and the mechanism of action of electromagnetic fields on blood. It conduces to the accurate mathematic model of blood flow in electromagnetic fields.
