数学

Keeping to the standpoint of secondary normal schools, we study teachers and students' sense of mathematics application as well as the sense of appraising the talent; on the other hand, we pay more attention to the research textbooks' content system and teaching method. Combining the reformation of new courses,advanced that the mathes courses reformation of normai school must in front of the elementary school.The application of mathematice by some basic attitude , Make normai school students livinged to apply mathematics be used as a kind of basic standpoint with the attitude, melting into its the character of the whole..

结合新课程改革对师范学校的课程内容体系、教学方式进行研究，从师范教学的师范性和示范性特点出发，提出师范学校的数学课程改革应走在中小学课程改革的前面；培养中小学学生的数学应用意识应从培养师范生入手，使师范生把数学应用作为一种基本的观点和态度，融入其整体素质。

The mian works are as follows:(1)By coprecipitation technique and coprecipitation- gel technique the nano zirconia powder was produced, factors affecting the properties of nano zirconia powder such as pH and the content of stabilizator are analyzed;(2)By the new pressless sintering process, the nano zirconia ceramic was produced, factors which can affecting the properties of nano zirconia sinter body such as moulding press and the sinter temperature are analyzed;(3)By the microtherm pressless sintering process, the nano copper added functional zirconia ceramic composite was produced, microscopic dimensionality and electric properties of such sinter body and the factors affecting such sinter body are analyzed;(4)By the self-invented "external albumen coating" technique the zirconia powder was successfully coated by carbon in the corresponding sinter body, which can help solve the traditional aggregation problem to some degree;(5)Based on analyze the characteristics in the nano powder sinter process, the "three-ball sinter model" was proposed, for the relationship between the relative density and porosity of sinter body, by mathematical fitting, such model was successfully verified.

本研究比较系统地研究了纳米氧化锆陶瓷的合成与成型机理，特别是讨论了纳米氧化锆陶瓷的稳定性，为防止纳米颗粒在外场作用下的团聚和长大提供了理论基础和实验数据，具体工作有以下几方面：(1)采用共沉淀法和共沉淀-凝胶法制备了纳米氧化锆粉体，并分析了pH值和稳定剂含量对粉体性能的影响；(2)采用新型无压烧结工艺制备了纳米氧化锆陶瓷，并分析了成型压力和烧结温度对烧结体性能的影响；(3)采用低温无压烧结工艺制备出添加纳米铜的功能性纳米氧化锆复合陶瓷，并分析了烧结体的微观尺度和电学性能的变化以及影响因素；(4)通过自创的&鸡蛋清外敷法&在真空镀膜台上对纳米氧化锆粉体进行包敷碳颗粒的表面处理，并采用真空烧结工艺制得相应烧结体，初步开始解决陶瓷烧结过程中团聚长大这一传统难题；(5)通过分析纳米颗粒在制备烧结体过程中的实际特点，提出了&三球烧结数学模型&，通过引入坯体相对密度和孔隙率的相对关系分析并通过自行编写的数学拟合软件，验证了这一数学模型。

Beside this, I also made a clear definition of Curriculum Resources of Mathematics and stapled it.

本文主要研究了三个问题：第一，采用文献法对课程资源与数学课程资源研究现状进行了梳理，在此基础上，界定了数学课程资源，并将数学课程资源进行了分类。

In order to improve the level of children education and the quality of teachers in kindergartens, it's extremely important to improve the mathematics quality of stude...

数学素养是近年来在数学教育领域中较受关注的研究课题，但是针对幼师生数学素养的研究却很少。

Concretely, there are 3 factors that directly influence the transformation by extent: teachers\' mathematics teaching experience, their mathematics view with which they tend to handle mathematical problems, and the transfixion degree of their understanding about mathematical knowledge.

具体来说，影响的直接因素有三个，按影响程度由大到小，它们依次是教师的数学教学经验、教师的问题解决取向的数学观、教师对数学知识理解的贯通度。

Under the definitions of the probability and the expected values of unhit attacking missile quantity,the expected values of anti-missile quantity and attacking missile quantity hit by a single anti-missile,the weapon operation efficiency was presented at various engagement pattern...

在定义未被命中的来袭导弹概率和数学期望、反导导弹数量的数学期望、单发反导导弹命中来袭导弹数学期望概念的基础上，研究不同作战方式下的武器作战效能。结果表明：提高导弹武器的效能，最为可行的方式是采用2发为单位的齐射。

Even though mathematics and physics have been related for centuries and this relation appears to be unproblematic, there are many questions still open: Is mathematics really necessary for physics, or could physics exist without mathematics?

即使数学和物理学几个世纪以来有关并且这关系看起来是unproblematic，有很多问题仍然打开：数学对于物理学真的必要，还是物理学能没有数学而存在？

In this paper,the correlativity between the Brinell hardness and the Rockwell hardness has been investigated by regression analysis,the regression equation between the Brined hardness and the Rockwell hardness is obtained,therefore the quantitative analysis can be carried out.

本文根据布氏硬度与洛氏硬度之间的相关关系，采用数学回归分析方法，求出它们之间的数学表达式──数学回归直线方程，从而能定量地阐述两者之间的关系

With the rapid development of the electronic technology, the graphing calculators begin to enter the field of mathematical educational technology, which is going to have a great effect on the reform of mathematical course and the methods of students′ learning mathematics.

随着电子技术的飞速发展，图形计算器开始进入数学教育技术领域，它的出现将会对数学课程改革和学生数学学习方式产生影响。

Participation pedagogy is also a main method to train the students consciousness of innovation , of self-training, and of intercommunicating on their own initiative .

本文在现代教育学，心理学的理论支撑下，根据&参与式教学法&的基本方式方法，在幼师数学课堂教学中进行了参与式教学的应用与研究，根据幼师数学教学的特点与学生的特点，提出了在幼师数学教学中将传统教学模式与参与式教学法相结合的教学方法。

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。
