alloy(名词/动词):
/l/
Alloy is stronger than pure metal. 合金通常比纯金属更坚固。
The jeweler alloyed gold with copper to increase its durability, but some critics said the change alloyed the ring’s original beauty. 珠宝匠把黄金与铜合成合金以提高耐用性,但也有人批评这种改变玷污了戒指原本的美感。
alloy 源自古法语 aloi / aloy,与“按标准混合金属、确定金属成色与品质”相关,后来进入英语,既指“金属的混合物(合金)”,也引申出“掺杂导致品质下降、使纯净受损”的含义。
