坚硬的东西往往是脆弱的,比如你嘴里的牙,而那些看似柔软的东西却往往充满韧性,比如你家的老藤椅。一个鲜为人知的事实是,面对安全和节能这对矛盾体,金属材料的轻量化可以用奇妙的科技化解难题。 Hard things are often fragile, such as the teeth in your mouth, while those seemingly soft things are often full of tenacity, such as your home old wicker chair. A little-known fact is that in the face of the contradiction between safety and energy saving, the lightening of metal materials can solve problems with fantastic technologies.
