“一个气体分子就可以破坏玻璃的硅氧键，并诱生一个缺陷。”Pennsylvania州立大学的材料科学教授Carlo G . Pantano说。

Even one gas molecule can break a silicon-oxygen bond in glass, generating a defect, said Carlo G. Pantano, a professor of materials science at Pennsylvania State University.

因此，通过测量树的不同年轮(ring)中两种氧同位素的比例，并将结果比对年轮所显示的树龄，就可再现树木一生中所经历的所有飓风。

So, by measuring the ratio of the two isotopes in the rings of trees, and matching the result to the age of the ring, a history of hurricanes spanning the life of the tree can be reconstructed.
