Whether such allotropes exist remains to be seen.

这种同素异体是否存在还有。

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，这种元素的新物理式，即同素异体，可能会提供解决部分燃烧和毒性问题的方法。

Very reactive form the other allotropes, black and red phosphorus, are not as reactive and are much, much easier for us to handle.

同素异体， 如黑磷和红磷相比， 白磷非常活泼， 而黑磷和红磷则不那么活泼，且更容易由我们来处理。

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体)。
