摘　　要：容积导电模型研究可用于容积导电系统的设计和能量传递参数的优化。笔者考虑电路、电场和温度场的相互耦合关系,建立了容积导电的三维多场耦合模型。该模型在电路层面上实现了容积导电的仿真,皮肤组织温升的实时监测,为能量传递的优化设计提供了直接的理论指导。利用软件FEM3.5搭建了容积导电多场耦合模型,从多物理视角验证了容积导电能量传递的可行性,为进一步优化能量传递效率奠定了基础。The research on volume conductive model can be used in designing the conductive systems and optimizing the energy transfer parameters. By considering the coupling of circuit, electromagnetic-field and temperature-field, a 3-D multi-filed coupling model is developed. On the circuit level, the simulation of volume conduction, real-time monitoring for the temperature of skin tissue are achieved, which provides direct theoretical guidance for energy transfer optimization design. With the software FEM 3.5, a volume conduct multi-field coupling model is built to verify the feasibility of volume conduction, which also lays foundation for further optimize energy transfer efficiency.
