On the basis of brief introduction to fundamental theory of FD8, a new algorithm to accurately calculate the effective contour length in the accumulated flow partitioning involved in 1n computation by using internal tangent circle on conical surface method was proposed.

本文首先介绍了多流向算法的基本原理，并基于此对流动累积分配中的有效等高线长度精确计算提出了几何锥面内切圆算法，同时改进了传统的地形指数中单位等高线汇流面积α的计算方法，增强了多流向算法对DEM中异常栅格的处理能力。

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.
