However, the mean atom distance depends on not only the cluster size, but also the cluster structure, which can be regarded as the criterion of determining the structure transformation.

平均原子间距不但依赖于团簇的尺寸，且对团簇结构的变化敏感，可以作为非晶与密堆结构晶体转变的一个判据。

And given economic uncertainties, we will take more radical actions to accelerate our transformation and reduce quickly our costs structure, especially in Europe.

FORBES: Alcatel-Lucent Warns On Weak Q4; Shares Crushed

Today, we have an enlarged NATO with increasing (though still far from adequate) capabilities, a good plan for streamlining NATO's command structure, a new NATO four-star command focused specifically on military transformation and an affirmative answer once and for all to that old chestnut, can NATO take on a mission out of area.

This could leave the services vulnerable if one of the other major contingencies resolves itself before we have a transformation strategy in place, creating a strong demand for immediate, deep, and unwise cuts in force structure and personnel.
