另外，可以使用数据库或者Trac和Lighthouse等系统(见参考资料中的链接)在配置的整个生命周期内(从请求实现直至取消)跟踪对配置的修改。

Further, use a database or a system such as Trac or Lighthouse (see Resources for links) to follow the life cycle of a configuration change-from request to implementation to expiration.

注意，增加这一个智慧与在项目生命周期的结尾阶段获得参考体系结构的成果是不同的。

Note that adding this wisdom is different than harvesting assets for the reference architecture at the end of a project lifecycle.

So if you want to on an exam, you can just write this down quickly at the beginning and refer to it as you're filling up your electron configurations, but also if you look at the periodic table it's very clear as you try to fill it up that way that the same order comes out of that.

如果你们想要在考试中，你们要在开始时快速地把这个写下来,然后在填充电子构型,的时候参考它，但是如果你们看着周期表,它就非常清楚了当你们将它用从那产生的,同样的顺序来填充。
