Modeling experiments told the researchers that an asymmetrical deflection of light would create a surprisingly stable lift force.

模型试验告诉研究人员，光线的非对称偏转可以产生稳定的提拉力，这令人惊奇。

In my last installment of this column, I discussed how XML knowledge management systems such as RDF shed a different light on age-old problems of data design and modeling.

在本专栏的上一篇文章中，我讨论了诸如rdf这样的XML知识管理系统是如何另辟蹊径解决数据设计与建模这些老问题的。

For example, if we are modeling a new kind of traffic light, we may want to start at the level of the citywide traffic system, so that we can place the traffic light in its context.

例如，如果我们要对一种新的交通灯进行建模，我们可能希望从全市交通系统的层级开始，以便我们能够将交通灯置于它的上下文中。
