Whether such allotropes exist remains to be seen.

这种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).

一种元形体可能此具有非常不性质(例如，石墨和金刚石都是碳形体)。

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

这种材料是碳形体，具有独特物理特性，使其处于先进材料研究前沿。

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.

研究员认为，这种元新物理形式，即形体，可能会提供解决部分燃烧和毒性问题方法。
