未充分利用

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。

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。
