So when the fibre is drawn the researchers apply a powerful electric field to ensure that the molecules in the plastic all line up in the same direction as the fibre cools.

当纤维提取出来后，研究人员会对其施加一个强大的电场，以保证纤维冷却后，塑料的分子都按照同一方向排列。

It contains two parts: calculation about the equivalent charge of the unit length line and calculation about the electric field caused by these charge.

它主要由两部分组成，即计算单位长度导线上的等效电荷，及计算由这些电荷产生的电场。

Again, in an electric field line splitting observed, the intensity of the line splitting varying with the intensity of the applied electric field.

结果也证明谱线在电场中也会分裂，而且其分裂程度,随电场强度变化而变化。

And when a magnetic field line vibrates, he says, it makes an electric field which excites current in wires.
