Whether such allotropes exist remains to be seen.

这种同素异形体是否存在还有待观察。

Allotropes of an element can have very different properties from each other (graphite and diamond, for example, are both allotropes of carbon).

一种元素的同素异形体可能彼此具有非常不同的性质(例如，石墨和金刚石都是碳的同素异形体)。

The boffins behind it think that new physical forms of the element, known as allotropes, may offer ways around both the partial-combustion and the toxicity problems.

研究人员认为，这种元素的新物理形式，即同素异形体，可能会提供解决部分燃烧和毒性问题的方法。

This fascinating material, an allotrope of carbon, presents unique physical properties that have positioned it at the forefront of advanced materials research.

这种迷人的材料是碳的同素异形体，具有独特的物理特性，使其处于先进材料研究的前沿。
