科学家研发出世界首个“不可切割的”物质，灵感来自葡萄柚和贝壳

Researchers have developed an "uncuttable" material capable of deflecting grinders and cutting tools in what is thought to be a world first.

研究人员研制出一种“不可切割的”物质，可以使研磨机和切割工具偏移，属世界首例。

The material, known as Proteus, is six times lighter than steel due to its porous make-up.

这种物质被称为Proteus，由于是多孔结构，所以比钢轻6倍。

One of the people behind the invention, Dr Stefan Szyniszewski from Durham University, told Sky News that materials such as grapefruits and molluscs inspired the creation - believed to be the first manufactured uncuttable material.

它的发明者之一、来自杜伦大学的Stefan Szyniszewski博士对天空新闻台说，葡萄柚和软体动物等物质给了他们灵感，这是第一个人造的不可切割的物质。

Dr Szyniszewski said the mollusc shell was the "more important" of the inspirations, adding: "The seashell is very resistant to predators, so it doesn't open easily when the shark wants to eat it.

Szyniszewski博士说软体动物的外壳是更重要的灵感来源，并且补充道：”贝壳对捕食者非常有抵抗力，当鲨鱼想吃它们时，它们绝不会轻易张开外壳。“

"It's quite surprising, the resistance of the shell is about 2,000 higher than the bricks it is made of.

”令人惊讶的是，贝壳本身的抵抗力是组成贝壳的砖块的2000倍。“

"This is because when you try to cut it open, the crack has travelled via this maze of this soft material in between the hard brick and this takes a lot of energy."

这是因为坚硬的砖块之间有错综复杂的柔软材质，当你试图切开贝壳时，裂缝在这些柔软的材质中穿行，因而会花费很大的能量。”

Dr Szyniszewski, part of a team of researchers from England and Germany who created Proteus, added: "What I'm really excited about is that it's just a concept, so we made it out of steel and ceramic spheres."

发明Proteus的研究团队成员们来自英国和德国，作为其中的一员，Szyniszewski博士补充说道：”我很兴奋，因为这还只是一个概念，我们是用钢铁和陶瓷球制造它的。“

Dr Szyniszewski said the spheres can be swapped out for other materials, like plastic or foam, but still remain strong.

Szyniszewski博士说，球体可以换成其他材料，比如塑料或者泡沫，但整体依然会保持坚固。

He puts Proteus's "uncuttable" nature down to the way the ceramic spheres inside the steel act as "mini sandbags", which will break into particles and resist fast moving objects, such as grinders and saws - even blunting them against their own force.

他把Proteus的”不可切割“性归结于，钢铁中的陶瓷球充当了”微型沙袋“的作用，它会破碎成颗粒并抵抗快速移动的物体（比如磨床和锯子）。而这些物体甚至会因为切割产生的力而自身发生钝化。
