电流极子在均匀导电球模型中电位解析解的数值验证

Numerical Verification of the Analytic Solution of Electrical Potential in a Homogeneous Conducting Sphere in Numerical Value

80年代以来 ,基于脑电图进行无创性病灶定位的研究 ,特别是基于等效电流极子定位法 ,得到了相当的发展并已经投入到正式的临床应用之中 ,因此等效电流极子模型在脑电图分析中逐步得到了广泛地应用。本文在参考了国内外学者对于电流极子在均匀导电球模型中的电位解的求解思路 ,进一步推导出电位解析解的表达式 。

Since the 1980s, the research of non-trauma orientating based on EEG has been developed considerably. Especially, the method of equivalent moving dipole model has been applied to analysis of EEG. In this article, reference to some scholars' work, we deduce the analytic solution of electrical potential in a homogeneous conducting sphere(the positions of multiples are discretional in the sphere model),and then verify its accuracy by some collected data.
