But Hazen said only a small number of all possible combinations would " work."

但哈森说，所有可能的组合中只有一小部分会“奏效”。

" With 2,000 drugs to start with, I could produce all possible combinations, a billion possibilities" to test in vitro.

“根据一开始的两千种药物，我可以制造出所有可能的组合，一百万种可能”来进行体外测试。

For several hundreds of millions of years, the molecules mixed together, rearranging themselves in all possible combinations, becoming ever more complex.

在数亿年的时间里，这些分子混合在一起，以各种可能的方式重新组合，变得越来越复杂。

Those tickets covered 60 percent of all possible number combinations.

这些彩票涵盖了所有可能号码组合的 60%。

You'll choose three different scalers, scale each of those vectors, and then add them all together, and again, the span of these vectors is the set of all possible linear combination.

你会选择三个不同的标量 缩放每一个向量 然后把它们加在一起 同样 这些向量张成的空间是所有可能的线性组合的集合。

Well, their span is the collection of all possible linear combinations of those two vectors, meaning all possible vectors you get by scaling each of the two of them in some way and then adding them together.

它们张成的空间是这两个向量所有可能的线性组合的集合 也就是说所有可能的向量都是通过将它们分别缩放然后相加得到的。
