作为结果的

That which has a cause is of the mind, that which has an effect is of the mind; and to know the causeless, the eternal, that which is beyond time, the mind, which is the effect of time, must come to an end.

有原因的东西是来自是心智的、有结果的东西是来自心智的，而要知道那无缘无故的、永恒的、超越时间的东西，作为时间的结果的心智，必须终结。

Then it proves a necessary and sufficient condition for anamalgamation of two 3-manifolds with toms boundary with no new incompressible surfaces.Lastly, with the help of the condition and the theorem about the classification of allautomorphisms of a torus, it is proveed that there exists infinitely many 3-manifolds each ofwhich contains no incompressible surfaces besides a torus.

According to the principles of synthesis, dominance, regionality and relative consistency, the environment degradation evaluation system is divided into three classes: vulnerable region, vulnerable type and vulnerable cell. The research area belongs to the erosion degraded Southern Red Hilly Area region. Based on the conceptions and grading, the dissertation probes into the methodology of evaluation and case study, and establishes a potential degradation evaluation system which comprises altitude, gradient, soil erosion index K, annual rainfall, the proportion of rainfall in raining period, and the drought index of rainless period.

在脆弱性概念及其分类的基础上，本文进行了脆弱性评估的方法探讨和实证研究，在脆弱性分析的基础上，选择高度、坡度、土壤可蚀性K值、降雨量、暴雨量、多雨期降雨比重和少雨期干旱指数为潜在脆弱度指标；选取作为区域人地关系、社会经济发展与管理水平综合影响结果的人类活动指标森林覆盖率和坡耕地指数作为现实脆弱度评估的人为加速侵蚀的修正指标，计算生态环境的现实脆弱度，并将其指标体系与方法用于衡阳盆地生态环境脆弱度评估的实证研究。

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.

结果表明，所合成的化合物B的结构与预期的结构一致；热性能研究表明，化合物B在242.2~750℃质量损失为54.39%，1000℃时仍有25.11%的炭残渣，显示出优异的热稳定性和成炭性；在相同反应条件下，用乙腈作为溶剂的反应产率比使用氯仿和二氯乙烷为溶剂的高，并且在合成过程中，单独使用三乙胺作为缚酸剂时产率很低，而当同时加入少量4-二甲氨基吡啶时，产率可达81%。

People can examine the fifty years' existence of the European Union from various perspectives, for example, from the perspective of chronology with great events being the clues; or people also can make evaluations on the success and failures of the European Union on the basis of a series of significant internal changes within the EU; using interesting theories as the mainlines of discussion, some other experts may explore certain important issues related to sovereign states and supra-sovereignty, the democracy in the international organizations and so on.

内容提要：人们可以从多种角度考察欧盟存在50年，例如以50年间发生的一些大事为线索，把它写成编年史，或者发展阶段史；以欧盟内部发生的一系列重大变化及其结果，论述其成败得失；以若干人们感兴趣的理论问题作为讨论的主线，研究主权国家与超越主权、国际组织中的民主问题等等；而本文则把主题确定为阐明欧盟在其存在与发展的半个世纪里，它在全球生活中所起的三项主要作用，即欧盟作为一股积极的力量、平衡的力量和&榜样&的力量对外部世界发生的影响。

Based on the analyses above, the research proposes some suggestions for protecting herdsman's rights and interests and inhibiting grassland degradation. They are:(1) Building the system of grassland resources dynamic monitoring;(2) Promoting the transformation: the congnition of herdman on grassland degradation to action; and peasant household as the basic production unit to the unit of production +ecological construction;(3) Perfecting the Household Contract System, promoting the use right transfer, exploring the new mechanism of grassland utilization;(4) Changing the guiding ideology of policy and measurement from pursuing the supply of products to muliti-function of grassland;(5) Promoting the development of organic animal husbandry.

以这些分析结果与观点为基础，本研究提出一些有助于保护牧民利益、抑制草地退化的政策与建议：(1)建立草地资源动态监测体系；(2)促进两个转变：牧民对草地退化影响的认知向行为转化、牧户作为单纯的生产单位向生产与生态保护单位相统一转变；(3)在稳定、完善草场承包制度的基础上，以草地使用权流转为切入点，探索草地资源利用新机制；(4)政策与措施的指导思想要由单纯追求畜产品的供给向发挥草地生态系统多功能性转变；(5)将有机畜牧业可以作为转变生产方式的一个选择进行试点与发展

The results show that the composite compound observed is mainly composed of TiC, CaS and CeS; the nucleation sequence of the phases during the solidification of the alloy is CeS→TiC→austenite; the (100) crystal plane of CeS and the (001) plane of TiC, and (100) plane of TiC and (001) plane of austenite match perfectly; CeS can act as the heterogeneous nucleating center of TiC, and TiC can act as the nucleating center of austenite.

Eurhythmics, a favorite activity of students, is thus used as the main strategy to design teaching activities, with the aim to enhance the ability of improvisation.

研究方法采行动研究法，根据研究者在教学现场所面临的困境：学生普遍缺乏创作的动机，因此，以提升即兴创作能力为目标，运用学生最喜爱的肢体律动为教学策略，设计教学活动行动方案，并且采用实验教学，以行为观察纪录表与统计、即兴创作影音档案及音乐日记作为呈现实验结果的依据，是属於质、量并陈的研究，其研究之结果分述如下

Action research is adopted as the research method. Based on the difficulty faced while teaching music, this researcher feels that students in general lack the motivation to be creative. Eurhythmics, a favorite activity of students, is thus used as the main strategy to design teaching activities, with the aim to enhance the ability of improvisation. In addition, experimental teaching is adopted and the results presented by the researcher with a behavior observation record sheet and statistics, as well as audiovisual files of improvisation and musical diaries from the students. It is a combination of qualitative and quantitative research, whose results are presented as follows: 1. Designing the principle of a eurhythmics lesson: It starts from "listening" and applies elements of eurhythmics (force→space→time→relationship→locomotor →group formations) in teaching rhythm. It not only accumulates musical ability and experience, but also becomes the source of improvisation.
