在这样的实例中，系统分析人员可能会决定只确认那些确信因子在或高于一个具体限制——比方说80%——的特性作为确定的需求。

In such instances, the system analyst might decide to validate only those features whose sureness factor is at or above a specific limit — say 80 percent — as firm requirements.

首先，它帮助划分需求的优先级，因为您可以将每个特性追溯到期望，并用确信因子标记它们。

First, it helps prioritize requirements, because you can trace every feature to expectations and then tag them with a sureness factor.

这一新研究领域依赖于获得被称作转录因子的主蛋白质，这种蛋白质控制细胞中哪组基因被激活，从而也就控制了细胞拥有哪些特性。

The new field depends on capturing master proteins called transcription factors that control which sets of genes are active in a cell and thus what properties the cell will possess.

and we like log algorithms, because they're really fast. A typical characteristic of a log algorithm is a pro-- or sorry, an algorithm where it reduces the size of the problem by a constant factor.

并且我们也很喜欢对数算法,因为它很快,对数算法的典型特性是高速，哦，抱歉，是他能以常数因子的速度,降低问题的大小，很明显。
