With technology advanced day by day, the reliability of electronic products is improving gigantically too. However, an electron system to date tends to contain more and more components when its functionality becomes more complex. Even when the reliability of every single component is high, the probability of a system becoming erroneous is also high if the interactions between components are faulty. For systems used in a critical mission, fault is unendurable and unacceptable.

中文摘要虽然现今电子技术的进步日新月异，产品的可靠度也一直在改善，但在今日电子系统的架构趋於复杂，以致所需组成的元件也变多，单一元件纵使具有高可靠度，但大量的元件组合在一起之后，其出错的机率便会大增，进而抵消掉元件本身的可靠性，这是在某些应用於关键性任务的系统而言，因其无法忍受错误的发生，所无法接受的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
