According to this theory, the stress intensity factor around the crack-tip is a function of several variables, while Irwin's stress intensity factor K1 is a constant, therefore the factor K1 becomes a particular case of the generalized factor K1g.

作为钝角裂纹模型的K1g将在无限细的数学裂纹的尖点上退化为K1。广义应力强度因子的表达形式为风K1g＝ηK1，其中η是一个多变量函数，它是一个对于K1；的修正系数。在数学裂纹尖点上有η＝1。

Based on the results of the statistical analysis of a large amount of measured data in excavation,a fundamental theoretical model of ground surface movement due to deep excavation is established by using the fuzzy measures theory of fuzzy mathematics.

采用模糊数学中的模糊测度理论导出了深基坑开挖引起的周围地表移动变形问题分析的数学模型，并用该模型对深基坑开挖引起的周围地表移动变形工程实例进行了具体的计算分析。

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.
