超导电体

In chapter 1, the background of the development and formation mechanism of chiral supermolecules assembly, chiral mesoporous materials and chiral conducing polymers, have been detailedly elaborated.

第一章中，简单介绍了手性超分子体的发展及其形成机理，综述了手性介孔材料以及手性导电高分子材料的合成、形成机理以及最新研究进展，并对本文工作的背景进行了详细的阐述。

Strangely, the best electrical conductors, copper and silver, do not become superconductive.

说起来很奇怪，最好的导电体像铜和银都不能成为接近绝对零度仍能导电的超导电体。
