多元微合金化、复合接触导线的研究与制备以及具有创新的国产化加工技术是接触导线今后的发展方向。

The future tendency on contact wire includes the development and preparation multi- micro - alloying and compound contact wire as well as innovative owned - processing technology.

接触导线与一方的钕磁铁，将导致它的自旋。

Contact of the wire with the side of the Neodymium Magnet will cause it to spin.
