“无限长”平行导体回路单位长度自感的精确计算

The Precise Calculation of the Induction on Unit Length Of Two "Infinite Length" Parallel Conductor

给出了两根"无限长"平行导体回路单位长度自感的一种精确计算方法,并证明了其近似结果与中部附近单位长度上的自感相同。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。

This paper gives a new kind of method precisely computing the induction on unit length of two 'infinite length' parallel conductors and showed that its approximate result is the same as the calculated induction on unit length in the near middle of two 'infinite length' conductors. 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.
