They often have interesting properties, such as poor heatconductivity (which makes them good insulators) and low friction (which makes them slippery).
它们拥有很有趣的特点,例如导热性差(可以做很好的隔热材料),以及低阻力(意味着表面很滑)。

Metals are elements that can be defined by their properties, such as ductility, toughness, malleability, electral and heatconductivity, and thermal expansion.
金属是根据可锻性,刚性,可塑性,电热导通性以及热膨胀度等特征来定义的多种元素的复合物。
