摘　　要：利用诺依曼公式和数值积分软件,计算出两平行共轴矩形截面圆线圈的互感系数,同时分别利用电感仪表、伏安法和电磁感应法对互感系数进行测量。实验测量值与理论计算值之间的相对误差均低于5%,实验与理论计算相互验证,得到互感系数和耦合系数随两线圈之间距离的变化曲线,从而对设计互感线圈提供理论参考。Using Neumann formula and numerical integration software,the mutual inductance of two parallel coaxial rectangular section circular coils is calculated,and the mutual inductance is measured by inductance instrument,volt-ampere method and electromagnetic induction method respectively.The relative error between the experimental measured value and the theoretical calculated value is less than 5%.The experimental and theoretical calculations verify each other,and the variation curves of mutual inductance coefficient and coupling coefficient with the distance between the two coils are obtained,which provides a theoretical reference for the design of mutual inductance coils.
