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.

本文详细讨论了WGS84大地坐标转换到北京54坐标系下的高斯平面坐标的方法，重点介绍了WGS84和北京54的空间直角坐标的转换模型及转换参数的计算方法，并根据不同的模型和计算方法结合实际数据进行计算和结果的比较，认为采用基线向量求解的四参数模型具有较高的转换精度，分区变换和提高控制点精度也能提高转换的精度。

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.

交际能力和语法的关系应该是目标与途径的关系。
