Firstly the theoretical models of reflective optical fiber bundle sensors were put forward for their general applicability, which can provide guidance for the design and implement of such sensors. Based on such theoretical models, an embedded optical fiber bundle sensor is implemented for displacement measurement in fine machining and precision controlling. Secondly the design and implement of an embedded network interface was presented, which can connect the sensors into Fieldbus network, IP network, wireless communication network and so on. Lastly the sensor structural design based on embedded microprocessor and real-time operation system, the software structural design based on multitasking and monocycle were presented, which can increase the real-time and reliability features of signal processing and transmission.

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
