0引言放样路堑开挖线的传统方法是将仪器架设在线路中线上，沿线路中线的法线方向用距离来寻找开挖线的位置(即中线设站距离逐点逼近法)[1]。

Meanwhile, The complicated computation of the laying-out procedures can be accomplished by means of PC-E500S or CASIO calculators to make the laying-out operation various and productivity improved obviously.

本文介绍一种新的方法，任意点设站坐标逐点逼近法，即利用可编程计算器或便携机配合全站仪，用坐标法进行路堑开挖线的放样，相对于传统方法，该方法不但在效率和精度上都有较大提高，而且可以根据需要和现场情况任意设站，使开挖线的放样更加灵活[2]。1施测原理1.1资

而本影像识别之方法采用离散最小平方法逼近 discrete least-squares approximation 晶粒边缘，用以求得晶粒形心与摆向方位角度。

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。
