新罕布什尔大学海岸应变研究中心主任南希·金纳( Nancy Kinner)解释说，石油钻井平台很少发生意外：“可能的危险概率在一千分之一或两千分之一。”

Nancy Kinner, co-director of the Coastal Research Response Centre at the University of New Hampshire, explains that oil rigs rarely have accidents: “The risk might be one in 1, 000, or one in 2, 000.”

冷战结束的数年后，北约国家普遍认为俄罗斯并未对其造成危险，所以不需要制定应变计划来保护新成员，例如波罗的海沿岸国家。

For years after the cold war, the orthodoxy was that Russia did not pose a threat, so NATO did not need to draw up contingency plans to protect newer members, such as the Baltic states.

该方法不仅能够考虑土的应力应变性质，而且能够在任意时刻确定最危险滑动面的位置及安全系数。

The method not only can consider behavior of stress strain of soil, but also can determine the most dangerous slip surface and its factor of safety at any time.
