The way on how to compute the optimal math＇s model is given and the survival condition of optimal root is discussed.

研究了一种特殊的订单生产——准时制下非核心企业的生产，分析了计划范围内的成本，并分别就各种成本给出求解公式，尤其在能力波动费用的求解上，引进了符号函数，解决了在任意单位时间段内能力累计的数学表达以及能力波动费用的数学求解，在以上基础上给出了最佳生产的数学模型，给出了求解方法，讨论了最优解的存在条件，最后，讨论了在APS中的应用前景。

So, rumination in mathematics learning is a key link in mathematics learning activities . But now it is a weak one among students.

因此反思性数学学习是数学学习活动的最重要的环节，但它是目前数学学习中最薄弱的一个环节。

The motor's dynamic model, which is generally employed for speed control and parameter estimation applications, is improved for the purpose of improving the parameter estimation accuracy by the assumption that the stator self inductance Ls is identical to the rotor self inductance Lr. The motor's dynamic response to a direct on line start is used to estimate the parameters.

详细给出了遗传算法应用于动态数学模型参数识别问题的一般步骤，在Kron动态数学模型基础上，假定定子自电感Ls和转子自电感Lr相等，利用异步电动机直接空载起动的特性，对异步电动机动态数学模型和简化模型的参数进行了识别，给出了识别参数及有关结果。

Therefore, the self-controlling ability has a variety of contents and manifestations.

具有数学学科自我监控能力是中学生数学思维和数学能力达到高水平发展的标志。

Based on the analysis of the connotation and extension of math self-controlling ability, and through means of quantitative and qualitative researches, we manage to design a questionnaire of our own to collect data, and then we have a quantitative analysis, and last we begin our qualitative analysis of structures, developing laws and regulating factors of self-controlling ability.

本论文在分析中学生数学学科自我监控能力内涵与外延的基础上，设计了定量化与定性化的研究，采用自编的中学生数学学科自我监控能力问卷收集数据，以数量化的证据为依据对中学生数学学科自我监控能力的结构、发展规律及其影响因素进行了定性分析。

The author put forward the self-monitor strategies during the process of mathematics study based on the problems is : Consolidate cognitive self-guidance and promote the development of thinking;Better self-confidence in the study of mathematica and active study of the students;Exer...

本文针对数学学习中的问题，提出数学学习过程中的自我监控策略：强化认知性自我指导，促进思维发展；提高数学学习的自我效能感，增强主动学习；运用适当的归因训练，转变学习态度，并进行相关的实验研究。

Learning of mathematical concepts of self-questioning approach: I can use mathematical symbols, graphics, mathematical language the essence of this concept?

对数学概念学习的自我提问方式：我可以用数学符号、图形、数学语言表述这个概念吗？

Mathematics concept is the basic point of mathematics content, the start point of lending theorem or rule, and the key point of setting up the theory system.

数学概念是数学内容的基本点，是逻辑导出定理、公式、法则的出发点，是建立理论系统的着眼点；同时，它又是学生认知的基础，是学生进行数学思维的起点。

Amused student has maths good mathematical faith is the base that develops activity of be used to of mathematical dug sexology smoothly.

数学好玩学生具有良好的数学信念是顺利开展数学探究性学习活动的基础。

Later In the secondary school I started to participate math classes at the university and got a lot of prizes in Latvia and even International Mathematic Olympiads '91 and ' 92 (not the first places of course, sill above average).

以后到了中学，我开始参加大学里的数学班，还获得了拉脱维亚国内数学竞赛的很多奖项，甚至还有'91 和' 92国际数学奥匹克的奖（当然都不是第一名，只是中等偏上）。

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。
