In this article some causation of slip and the calculation methods of freely setting station are first discussed,and then combined with the theory of polar coordinates a forecast method through distortion course curve analysis is put forward.

在阐述开挖事故原因的基础上，通过讨论全站仪自由设站的计算方法，并结合极坐标测量空间坐标的原理，提出了应用时空变形过程线分析变形趋势的预测方法，这种方法能够满足基坑安全监测工程的精度要求，并且成本低，速度快，能够为现场安全评估和方案设计提供可靠的数据基础。

In this article some causation of slip and the calculation methods of freely setting station are first discussed, and then combined with the theory of polar coordinates a forecast method through distortion course curve analysis is put forward. The method with its low cost and speediness, can satisfy the precision requirement and provide the base data for safe evaluating and designing.

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。
