摘　　要：研究了真实头模型下脑电场边界元数值求解过程中所遇到的一些问题，包括头部几何及电磁计算模型的建立，边界元自动剖分的完成，离散基函数的选取，自立体角的计算，消涨技术的使用，带调节参数的隔离问题的处理等．并利用具有解析解的多层同心球头模型分析了边界元的数值求解精度．通过对相关技术的全面讨论研究，开发出相应的应用软件系统．Several problems in the solution Process of electroencephalogram boundary element method based on relistic head model are studied, including the establishment of geometry and electromagnetic head model, the choose of the basic functions of BEM, the computation of auto solid angle, the employment of deflation technique and the processing of isolated problem, etc. The solution precision of BEM and analytic method is compared using the four-shell spherical model. A new thought has been formed through a thorough study on the relative techniques and a corresponding application software has been developed.
