These two naive characteristics is the reason of the conflicting between objectivism and subjectivism,the reason of the popularizing of positivism and irrationalism, of the crisis of science.

数学是以生活世界为基础的客观性真理，即它一方面作为生活技艺以及构造客观性的构想是主观的，另一方面它在直观世界中有其客观性。

This paper is focus on small set character recognition. Based on skeleton graphics, handwriting Chinese character is defined as a set of isolated branch, isolated loop and component. Relation among these three elements is also defined. Then, mathematical model is raised.

An Isothermal two-phase model has been proposed on the basis of theoretical and experimental study.

六、在理论和实验研究基础上，提出了等温两相数学模型，较好地描述了超临界苯烃化反应中催化剂结焦失活的过程。

A multi-level hierarchical image representation that preserves topological relation equivalency and a set of well-complete functional architecture that efficiently reflects this representation are presented, and the digital Jordan curve theorem is validated.

基于复形理论定义了数字图像空间的拓扑元素及其性质，在此基础上提出一套完备的保持拓扑等价性的层次表达数字图像的数学模型体系框架，并验证了层次表达结构中的Jordan曲线定理。

A new turbulence transport model with the k-ε theory in membrane separation has been formulated and implemented in this thesis.

在传递理论基础上，结合膜过程的传质方程和湍流的κ-ε模型，建立了适用于微滤和超滤过程的"沿膜管二维湍流膜分离数学模型"。

This research concentrates on the optimal factor selection of this modification with Kolmogorov test. The factor is a constant for all tolerance. This optimization method can bring a significant reduction of the difference between variation analysis and tolerance analysis. The thesis presents a framework to model and evaluate assemblies and their assembly process for autobody structure concept design. This framework makes the autobody structure concept design more science-based than experience based, and will significantly enhance the dimensional quality of autobody assemblies.

本文的研究以理论推导、数值模拟为主，结合生产实际数据的对比分析，在前人研究的基础上提出了并行车身结构概念设计方法，将依据经验的车身结构概念设计上升为依据严密数学推理和运算的过程，为进一步提高车身的尺寸质量提供了新的思路，同时对飞机、家电等薄板装配机械产品的设计和质量控制也具有重要的借鉴意义。

不仅如此，在积分学，级数理论等方面，以及以数学分析为基础的许多方面，拉格朗日中值定理也是研究问题的重要手段，经常发挥举足轻重的作用。

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。
