Higher limit function is an important part of mathematics, which is the theoretical foundation of calculus is to study a powerful tool for mathematical variables.

函数极限是高等数学的重要组成部分，它是微积分的理论基础，是研究变量数学的有力工具。

In theory we require linear independence among variables used as inputting or outputting of BP net when we model the mineral processing plant with BP net. However it is always definite relativity in inputting variables or outputting variables in modeling of the mineral processing plant, which sets definite obstacle in high quality modeling.

在应用BP网络建立选矿厂数学模型时，理论上要求作为BP网络的输入变量之间或输出变量之间应是线性无关的，而选矿厂数学建模中，输入变量之间或输出变量之间往往存在着一定的相关关系，这对建立高质量的模型设置了一定的障碍。

The model includes the mathematics model of the linear system and mathematics model of the non- linear system.

模型包括线性系统的数学模型及非线性系统的数学模型。

The main purpose of this study is to develop mathematical literacy test for pupils in elementary school.

中文摘要本研究旨在发展一份良好的国小学童数学素养评量工具，以供给教师、学校行政单位或数学教育相关研究作为参考依据。

After that according to conclusion of real checkout four surfaces by the curve log mathematics model the peeling optimization mathematics model is set up. Then comparison total solving the key technology and theory problems for the peeling veneer process from the beginning of changer the log centering checkout and the data procession to the final centering optimization process.

随后根据实测原木四个截面检测的结果，根据弯曲原木的数学模型建立起旋切定心优化的数学模型，从而比较完整地解决了旋切原木从上木、定心检测、数据坐标转换处理到优化定心过程中的主要关键理论、工艺问题。

Logic value in mathematics teaching indicts the significance of logic in mathematics teaching.

In chapter one, it gives a historical introduction to Russell' mathematics logicism and introduces how Russell put forward his idea.

第一章介绍了罗素形成数学逻辑主义思想的历史背景及其提出数学逻辑主义论题的情况。

Russell's great contribution to logic and mathematics was his defense of logicism—that is, the theory that all mathematics can, in some fundamental way, be reduced to logical principles.

罗素的巨大贡献，逻辑和数学是他的辩护logicism ，也就是说，所有的理论，数学可以，在一些基本的方式，将减少到合理的原则。

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。
