Graphene is an atomically thin, two-dimensional layer of carbon atoms arranged in a hexagonal lattice.

石墨烯是原子级薄的二维碳原子层，排列成六方晶格。

The reactors use " tristructural isotropic particle fuel" , in which blobs of fissile uranium (along with oxygen and carbon) are wrapped in layers of carbon and silicon carbide.

反应堆使用了“三结构各向同性颗粒燃料”，其可裂变铀（以及氧和碳）的斑点被包裹在碳和碳化硅层中。

This is understood to use heat and mechanical means to excite graphite flakes in such a way that the layers of carbon within open up, allowing impurities to be washed away with less-harmful chemicals.

这被理解为使用热量和机械手段来激发石墨薄片， 从而使内部的碳层打开，从而用危害较小的化学物质将杂质洗掉。

But Hurt and his colleagues have discovered a novel way to block them: with graphene, the substance composed of a single layer of carbon atoms. Hurt and his team asked volunteers to stick their arms into a box full of mosquitoes.

但赫特和他的同事们发现了一种阻断它们的新方法：用石墨烯，这种物质由单层碳原子组成。 赫特和他的团队要求志愿者把手臂伸进一个装满蚊子的盒子里。
