Sean Kay, a NATO expert at Ohio Wesleyan University, assessed the balance of forces.

俄亥俄卫斯理大学的北约问题专家肖恩·凯评估了力量的平衡。

It's about providing a balance of forces in the region.

这是关于在该地区提供力量平衡。

" But, in Haiti, nothing can be taken for granted. It depends how the current balance of forces in Haiti plays out, " Dupuy said.

他表示，" 但在海地，任何事都不能被视为理所当然。这取决于海地目前的力量平衡情况。"

To restore the balance of forces, researchers also need to understand how the stone in the walls and vault were altered by the fire.

为了恢复力量平衡，研究人员还需要了解墙壁和拱顶中的石头是如何被大火改变的。

That threatened a delicate balance of forces between the vaults, which push outward on the cathedral walls, and the flying buttresses which provide an inward stabilizing force.

这威胁到拱顶之间的微妙平衡，向外推动大教堂墙壁，以及提供向内稳定力的飞扶壁。

As firefighters hosed down the Cathedral, some stones gained almost a third of their weight in water-- further changing the balance of forces between the vaults and wall.

当消防员用水管冲洗大教堂时，一些石头在水中的重量增加了近三分之一——进一步改变了拱顶和墙壁之间的力平衡。

Thus the balance of forces was such as to allow a fair measure of stability of prices;— the highest quinquennial average for Sauerbeck's index number between 1820 and 1914 was only 50 per cent above the lowest.

因此，力量平衡使得可以公平地衡量价格的稳定性； ——索尔贝克指数在 1820 年至 1914 年间最高的五年平均值仅比最低值高出 50%。
