Whether such allotropes exist remains to be seen.

这种同素是否存在还有待观察。

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，可能会提供解决部分燃烧毒性问题的方法。

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

与其他同素， 如红相比， 白非常活泼， 而红则不那么活泼，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).

一种元素的同素可能彼此具有非常不同的性质(例如，石墨金刚石都是碳的同素)。
