同时给出了数学建模活动中应用AHP法的几点结论。最后，论文通过对送奶工现状的分析研究，运用AHP对送奶工进行了研究与评价，给送奶工管理工作提出了科学、合理的建议与措施。

Therefore, it is significant to research and develop a management information system of agricultural mechanization equipment for agricultural modernization. Based on the modern management theory, some mathematical modelings are constructed by system engineering theory, rough set theory, gray system theory, avail theory and neural network theory in this dissertation. It can resolve some actual problems, for instance, forecasting machine amount, agricultural machine power and prices.

本文在现代管理理论的基础上，运用系统工程、粗糙集理论、灰色理论、效用理论、人工神经网络等方法，进行数学建模，对未来农机需求、农机总动力、农机价格等问题进行探讨，并应用到农机装备管理信息系统的各个方面，对农业机械的各种信息进行传输、存贮、组织和处理分析，最终取得了较为理想的结果。

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。

Wavelets is developed in recent years and is rapidly used in the image process and sound analysis.

小波变换是近十几年才发展起来、并迅速应用到图像处理和语音分析等众多领域的一种数学工具。

Based on the fundamental of distillation,MESH model including equations of mass balance,phase equilibrium,mole fraction summations and heat balance for atmosphere-vacuum distillation column was established.

稳态流程与时间无关，是化工流程模拟中应用最为普遍的重要技术之一，需要建立质量平衡、相平衡、摩尔分数归一化和能量平衡等(MESH—Massbalances，Equilibrium relations，mole fractionSummations and Heat balances)方程构成的数学模型来描述其工艺流程中状态参数的分布情况[6，8-9]。

In this thesis, some problems about multivariate splines are discussed.

本文主要针对多元样条在应用中及与其相关的基础数学领域中提出的一些问题进行研究。

It has been proved in practice that the method is feasible for the optimal design of gear reducers.

故笔者应用模糊数学中的贴近度概念对二级圆柱齿轮减速器进行多目标寻优。

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。
