Doing so is mostly for human observers, as rule-engine optimization algorithms are sufficiently powerful to optimize rule matching.

这样做主要是为了方便观察者，因为规则引擎优化算法足够强大，能够优化规则匹配。

In an embodiment, rules are evaluated in an order specified by a rule list and step 320 identifies the first rule matching the received network packet, if any.

在一实施例中，以由规则列表所规定的次序来对各规则进行评价，且若有的话则步骤320标识与该接收到的网络分组相匹配的第一个规则。

In common IDS, the process of rule matching is usually traversing all rules. If using pattern matching in this process, it will exhaust more time and discard more packets.

在一般的IDS中，规则匹配的过程采用遍历法，如果匹配过程中使用模式匹配，则在高速网络下就会丢失较多的数据包。

Professor Robert Bonser, a cardiac surgeon from Queen Elizabeth Hospital in Birmingham, said that while the findings were "interesting", the scarcity of organs meant that gender matching was unlikely to become the rule.

There is an exception to this general rule, and that is when the 401(k) offers matching contributions.
