摘　　要：提出一种基于匹配法的逆问题求解方法,用于鸡胚胎心脏电流源偶极子矢量场的重建。在鸡胚胎承接装置上设置41个微孔,测量41个微孔点位的电势数据,采用匹配法计算并确定最优单电流源偶极子的位置、大小及方向,以重建鸡胚胎心脏电流源偶极子矢量场。仿真结果表明,所提方法能够比较准确地计算出单电流源偶极子的位置、大小及方向,并且有一定的抗干扰能力。An inverse problem solution based on the matching method is proposed for the reconstruction of the current dipole vector field of the chicken embryonic heart.The potential data of 41 points are measured through 41 micropore on the chicken embryo receiving device,and the position,size and direction of the optimal single current source dipole are calculated by the matching method,and the dipole vector field of chicken embryonic heart is reconstructed.The simulation results show that the method proposed can accurately calculate the position,size and direction of the single current source dipole,and has a certain anti-interference ability.
