摘　　要：对两根通电直螺线管串联时的等效总自感系数进行了分析,解释了两个不同计算公式之间的矛盾之处.通过建立自感与互感现象的物理图像,避免学生过于专注数学公式而忽略对物理本质的理解,有助于提高相关课程内容的教学效果.The equivalent self-induction coefficient of two electrified straight solenoids in series is analyzed,and the contradiction between two different calculation formulas is explained.By establishing physical pictures of self-inductance and mutual inductance,focusing too much on mathematical formulas while ignoring the physical nature is avoided,which is beneficial to improve the teaching effect of relevant contents.

关 键 词：自感系数 互感系数 物理图像
