Therefore it is possible to simply regard the value of the induction on unit length in the near middle of two "infinite length" parallel conductor as its approximate value.
故可简单的计算中部附近单位长度上自感作为“无限长”平行导体回路单位长度自感的近似值。

The design always is one kind of esthetics, with the mind induction creativity, deducts the design with the thought, the creation infinite possibility!
