The weighted Moore-Penrose inverse is a special generalized inverse which is an important basic tool in many branches of mathematics and has extensive applications in other fields such as economics, information processing, automatic control, etc. Recently, the study of generalized inverse of matrices associating with more general algebra such as ring, semiring and so on generalize the theory and methods of generalized inverse deeply and characterize the structure of algebra as well.

加权Moore-Penrose逆是一种特殊的广义逆，它不仅是许多数学分支的基本工具，而且在经济学、信息处理、自动控制等其他领域有着广泛的应用，近年来，结合环、半环等更一般的代数系统的矩阵广义逆的研究，不仅将广义逆的理论和方法作了更加深入的推广，而且也成了刻画代数结构的有力工具。

With the development of the information technology, more and more mathematics teachers use the Geometer's Sketchpad to create teaching environments.

随着信息技术的发展，广大数学教师越来越重视应用几何画板创设教学的情境。

How to appropriately use "Geometer's Sketchpad," in the classroom to Geometer's Sketchpad more conducive to the application of Shuoxingjiege the mathematical way of thinking, this paper is to be of concern.

如何适度使用《几何画板》，在课堂中让几何画板的应用更有利于体现数形结合的数学思想方法，是本篇论文所要关注的。

B Through theoretical and experimental studies, the paper investigats the relationships between hammer geometer and stress waveform generated by the hammer. After the mechanical meanings of linear model used by others are demonstrated, a simple expression of rigidity of an equivalent spring for direct impact between a hammer and a rod is obtained. Based on the above work, a mathematical model and numerical method for the impact of the hammer with progressively changing cross-section on the rod are presented.

2应用理论分析和实验研究相结合的方法，探讨了冲击应力波波形和冲锤形状尺寸之间的关系；阐明了冲锤与杆撞击局部变形的线性模型的物理意义，继而分析讨论了冲锤端头曲率半径与撞击弹簧刚度的关系；在此基础上，提出了连续变截面冲锤与杆撞击的数学模型和计算方法。

With the popularization and application of computer-making-graph technique in all trades and professions, this new technical medium is widely used in graph of function teaching as auxiliary mathematical classroom teaching at home and abroad, as strongly advances an in-depth study in graph of function teaching.

伴随着电脑作图技术在各行业的普及与应用，国内外函数图像教学中普遍采用这一新的技术手段辅助数学课堂教学，有力的促进了函数教学向纵深阶段发展。

As one of frame data of National Spatial Data Infrastructure , Digital Elevation Model excels contour line. it can express continuous gurgitation of ground, and it can also carry out relevant mathematical analyses and imitation, so it is applied broadly in various fields at present.

数字高程模型DEM是国家空间数据基础设施的框架数据之一，其弥补了等高线的不足，既能表示地面的连续起伏变化，又适合作相应的数学分析和模拟，现在已在各个领域得到了广泛的应用。

Haldane applied mathematical analysis to real world examples of natural selection such as the evolution of industrial melanism in peppered moths.

霍尔丹发表了一系列的论文，将数学分析应用到真实世界的自然选择例子，如椒粉蛾工业黑变病的进化。

Hamiltonian system is a important system in theory of differential equations and in nonlinear science research.

它也是非线性科学研究中的一个重要领域，广泛应用于物理与数学研究中。

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。
