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。

Small size, good self-healing effect, low inductance, low loss at high frequency, strong over-current ability, and can withstand high current impulse.

体积小、自愈性好，电感量低，高频损耗小，过电流能力强，能承受瞬间大电流冲击。

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。
