【摘要】：生物体系作为一类特殊材料,其电学性质是研究仿生材料设计、电阻抗成像以及电磁场生物效应的发生与防护等问题的基础。目前已有较多复合材料模型被应用于生物体系介电性质问题的研究,但由于生物组织离体后的介电特性会发生较大变化,故已有经典复合材料介电特性模型用于阐释生物体系介电特性还存在一定局限性。从几类典型复合材料理论模型的适用性出发,介绍了生物体系介电特性理论研究进展,总结了理论研究结果与实验测量结果的差异性。分析了复合材料理论模型在生物体系介电性质理论研究中应用的不足并提出了改进的建议,对复合材料理论模型在生物体系电学特性问题研究领域的进一步发展与应用等问题提出了展望。
[Abstract]:As a kind of special material, the electrical properties of biological system are the basis of studying bionic material design, electrical impedance imaging, and the occurrence and protection of biological effect of electromagnetic field. At present, many composite models have been applied to the study of dielectric properties of biological systems, but the dielectric properties of biological tissues will change greatly in vitro. Therefore, there are still some limitations in the application of classical composite dielectric properties model to explain the dielectric properties of biological systems. Based on the applicability of several typical composite materials, this paper introduces the progress of the theoretical research on the dielectric properties of biological systems, and summarizes the differences between the theoretical results and the experimental results. The deficiency of composite material theory model in the study of dielectric properties of biological system is analyzed, and some suggestions for improvement are put forward. The further development and application of composite material theory model in the field of electrical properties of biological systems are proposed.
