Firstly, the relationship of Atomic force and distance is studied. The scan type of samples and the working mode of probe is confirmed, then PZT is chosen as actuator for micro scan displacement, and optical deflexion method is used to detect the deflexion value of cantilever. After all these work, the system light path design is finished, and its mathematical model is completed.

This paper introduces the basic theory to develop coalbed methane reservoir. It compares coalbed methane reservoir with conventional natural gas reservoir on geology and production characteristics, and explains the storage and migration mechanism in detail. And it also provides a set of new integrated mathematics, numerical model for the simulation of degasification process from coalbed seams. At last, it presents a significant computer software corresponding with the model.

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.
