It's liquid at a very wide range of temperatures and being liquid is what you need to be able to be a solvent.

它在很宽的温度范围内都是液态的， 而液态是你需要成为溶剂的条件。

So amorphous solids don't have the sharp discrete melting points of things like ice, which melts exactly at 0, instead, they melt over a range of temperatures, as the heat energy increases.

因此，无定形固体不像冰那样具有尖锐的离散熔点，冰的熔点恰好为 0， 相反，随着热能的增加， 它们会在一定温度范围内熔化。
