近似度

The Eddington scheme is slightly more accurate in thicker optical depth region, while the two-stream DISORT is more accurate in the thin optical depth region where the solar zenith angle is less than 60 degree. Second, we compare the two two-stream schemes in a realistic atmospheric profile with gaseous transmission considered.

对于单层大气，Eddington 近似在光学厚度大的时候比二流离散纵标法更精确一点；而二流离散纵标法在光学厚度小且太阳天顶角小于60 度的时候更准确。

Two approximations to gradient have been introduced to reduce the computational complexity of the gradient based edge detection algorithm.

为降低基于梯度的边界检测算法的复杂度，常使用两种梯度近似算法。

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。
