发生的事是这样的：在纯净的一个钛和两个氧原子组成的重复单位下，二氧化钛是一种半导体。
What was happening was this: in its pure state of repeating units of one titanium and two oxygen atoms, titanium dioxide is a semiconductor.
对于多导体中所需要的单位长度电容和电感矩阵，使用矩量法进行分析。
The per-unit-length capacitance matrix used in multi-conductor transmission line coupling equation can be solved by Moment Method.
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。
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.
