This paper discussed the coordinate transformation method of WGS84 coordinate system to 1954-BeiJing Gauss grid coordinate. Introduced transformation model of WGS84 to Beijing 54 and computing method of transformation parameter. According to different model and computing method, computed and compared with the result combine real data. Think that adopt base-line vector quantity ask four parameters model have higher transformation precision.

Discrete Fourier Transform and Discrete Cosine Transform are used to get the descriptors of lip contours in the unsymmetrical lip contours model automatically. Hidden Markov Model is trained by using both of the descriptors as the eigenvector of lip contours, and then recognition ability is tested.4. Feature fusion is used to improve the classifiable power.

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.
