The problem of divergence produced by using line-model to calculate the tension and coefficient of self-inductance of a circular current loop is discussed.
分析讨论了一些文献在计算载流圆环处于自身磁场受的张力和自感系数时使用线电流模型的不当所带来的发散问题。
Because the total self-inductance coefficient is the sum of all the solenoids? Coefficients, the formulas are not valid in same of opposite directions.
串联后的总自感系数等于各螺线管自感系数之和，所以顺接和反接公式都不成立。
The measuring of self-inductance coefficient by means of direct current bridge method has reduced the difficult and improved the precision of measuring.
传统测量电感的自感系数是用交流电桥，它存在平衡点较难找，并且在空间杂散信号干扰下很容易产生误差。
