In this thesis, Based on the advantages of diode-pumped solid-state laser in Chapter 1, the development of diode-pumped solid-state laser is introduced. The trends of DPSSL are pointed out, the wide application fields ,as well as the bright market future of high power DPSSL are also summarized. In the Chapter 2 , all kinds of solid-state laser gain materials are introduced in detail. In the Chapter 3 , the theory on the mode-matching of the pump beam and the cavity mode is analyzed in detail based on the basic theory and work principle of LD-pumped all-solid-state laser.

The instruments the author used in the experiment are literature review, interviews, questionnaires and case study. Start from the point of view of strengthening amateur sportsmen's training method in view of the 400-meters sportsmen who haven't reached level 2 target in school PE teaching and amateur training according to the successful experience and long time of practice of some qualified 400 meters trainers and some out standing PE teachers as well as the accumulation of the related literature review the author construct theoretically the model of training 400 meters male dash with the target of improving the speed of 400 meters dash. That is to say from the following 4 aspics, speed index,speed endurance index,aerobic endurance index,strength index.Listing the relative theory of mode training by analyzing and comparing the results got by the subjects both before and after the experiment the author tries to find out a suitable final index mode for specific training .

本文运用文献资料法、访谈法、问卷调查和实验等方法，从重视基层业余水平田径运动员的训练、加强对业余水平运动员训练方法的研究为出发点，针对学校体育教学及业余训练中水平一般且未达到国家二级锻炼标准的400m跑运动员，依据国内400m跑专项高水平教练员、优秀体育教师多年训练实践的成功经验以及相关文献资料的积累，以影响400m跑专项成绩提高的主要内容指标，即速度指标、速度耐力指标、有氧耐力指标以及力量指标四个方面为切入点，从理论上初步对男子400m跑二级运动员专项训练的指标模式进行构建，并运用模式训练相关理论原理，通过实验前、后运动员成绩的对比分析，寻求符合其专项训练的最终指标模式。

Through improving the geometric parameters of the cemented carbide bit such as the rake angle of main cutting edge,outer fringe cusp and chis...

通过对钻削加工用硬质合金钻头的几何参数进行改进，主要是对主切削刃前角、外缘转点以及横刃进行改进，达到降低钻削功率的目的，同时，利用多元线性回归理论，得出基于实验数据的多元回归钻削功率的数学模型，从理论上证明此次刀具改进的有效性。

Since the mechanism and form of gluon confinement have not been known clearly, certain phenomenological models have to be used in many previous works. It is difficult to say that such investigations can give a reliable answer.

在理论上由于禁闭的机制和形式仍不十分清楚，不得不采取唯象模型，很难说它们能够给出完全可靠的理论预言。

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.
