After the optimal design, some parameters of the impeller such as entrance angle and diameter and have been changed. The improved impellers efficiency and cavitation performance are better than the former one.

通过对叶轮入口处的流场分析，证实了该泵性能下降是由汽蚀造成的推测；基于速度系数法建立了叶轮优化的数学模型，通过得到的流场数据和该数学模型对原叶轮进行了优化设计，优化结果对叶片的入口角和叶片的入口直径等参数进行了改进，优化后的叶轮达到了提高泵的汽蚀性能和效率的目的。

Although None-tax revenue has two basic functions: distribution function and adjusting function, excess unreasonable none-tax revenue brings negative effects: embittering enterprise's burden, dispersing state asset, aggravating unfair of social distribution, corrupting social moral and lower China's economic growth speed.

但过多不合理的非税收入也带来了负面影响：加重企业负担、分散了国家财力、加剧了社会的分配不公，败坏了社会风气、加重了我国经济增长速度下降的现状。

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。

First, we made a model of exhaustive exercise in rats, and used sucessfully the model in this study. We studied the effects of exhaustive exercise on adhesive behaviour of leukocytes in mesenteric venules by using an intravital microscope video system Its results indicated that the adhesiveness of circulating leukocytes to mesenteric venules enhanced after exhaustive exercise in rats.

首先，本文以游泳方法建立了大鼠模拟运动力竭模型，并成功地将此模型运用到本研究中；设计制作了肠系膜固定有机玻璃板，组成了一套活体显微观察实验系统；研究了大鼠运动力竭前后肠系膜微循环中白细胞粘附行为，结果表明：大鼠运动力竭后肠系膜微循环血流流态发生了明显的改变，大鼠运动力竭后肠系膜微循环中白细胞粘附性增强、白细胞滚动速率降低、在体白细胞变形性减小，将影响微循环正常的灌注，是导致微循环障碍发生发展的一个重要原因，进而最终表现为机体运动能力和运动质量下降。

Our projections were based on the successful launch of Manx products through Gordon Brown outlets.

Technique development, basic facilities improvement and cost decline make "globalization" communication possible. 4. Globalization of communication technique aggravates the "unfairness" of international communication and leads to its different layers, classes and unbalanced distribution. 5. The end of "cold war" deconstructs the opposite between the East and the West, but not ends the difference between the South and the North and the "civilization conflict". 6. The population redistribution makes the traditional nations and countries in the relevant areas unstable and influences the original national cultural identity. 7."Globalization" communication deepens the alertness of national elite intellectuals, which makes them strengthen their sense of mission to keep and guard the spiritual home of national traditional culture (including traditional belief, value, cultural pattern and so on) that will be possibly subverted and maliciously remade. 8. The combination of "direction" and "strategy", or the speciousness makes big trans-national media corporations sweep away all obstacles and occupy the markets in the developing countries, in which have appeared the phenomenon of "narrations of traditional cultures tending to similarities". 9."Global village": myth or reality? 10. The difference of culture and ideology often causes the different understanding and value judgement to the contents of trans-national communication.

第一部分将中国国家电视文化安全问题放到"全球化"的大背景中加以考量，分别从以下18个维度展开论述：1、全球化语境与我们的抉择；2、与"全球化"同样历史悠久的"国际传播"；3、技术的进步和相关基础设施的广泛建立并不断完善以及使用成本的持续下降，使得"全球化"传播成了可能；4、传播技术的全球化，加剧了国际传播的"不平等"，导致了国际传播的层级性和不均衡分布；5、"冷战"的终结解构了东西对立，但却并未终结南北差异和"文明的冲突"；6、人口的重新分布使得相关区域的传统意义上的民族国家面临潜在的不稳定，并有可能影响到原来各个国家已经定型的民族文化认同；7、"全球化"传播加深了民族国家精英知识分子的戒心，"守望民族传统文化的精神家园"的使命感使得他们开始关注核心的"传统文化"（具体包括传统的信仰、价值观、文化模式等）的有可能被颠覆或被恶意改造；8、"方向"与"策略"的有机结合，使得大型跨国传媒公司所向披靡，在发展中国家屡屡得手，很多国家出现了"祖母的同质化"现象；9、"地球村"：神话还是现实？

The work up that carries a system integratedly as our country and perfect, relatively fragile in the past highway, waterborne especially marine wait for contemporary carriage means, below the new condition of reforming and opening, grasp opportunity, produce respective advantage, realized rapid development, broke railroad the monopoly position in freight, reasonable billabong partial railroad freight flow, enlarged freight market share, improved composition of market of our country freight, the inevitable result that should say this is modernization of progress of economic progress, society, traffic, but will look from another angle, also mirror taphole road to develop become rigid of logy, mechanism, lack to innovate, the demand that incommensurate socialist market economy expands, from this and contractible, market owns the market share that cause rate drop considerably, what should say these are not traffic development is inevitable, what system of incommensurate socialist market economy leaves the field such as ability of means of system of as politic as railroad oneself development, management, sale, service is normal move have affinity.

随着我国综合运输体系的逐步发展和完善，过去相对薄弱的公路、水运尤其是海运等现代运输方式，在改革开放的新形势下，把握机遇，发挥各自优势，实现了快速的发展，打破了铁路在货运中的垄断地位，合理分流了部分铁路货流，扩大了货运市场份额，改善了我国货运市场结构，应该说这是经济发展、社会进步、交通现代化的必然结果，但是从另一个角度来看，也反映出铁路发展迟缓、机制僵化、缺乏创新，不适应社会主义市场经济发展的需求，由此而造成的市场份额缩小、市场占有率大幅下降，应该说这些并不是交通发展的必然，与铁路自身发展策略、治理体制、营销方式、服务能力等方面不适应社会主义市场经济体制下的正常运行有密切关系。

I have finished the ratio calculation of mw materials used to produce cementclinker, relative environmental impact importance assessment of emissions andenvironmental synthetic index under different conditions.the result means that we can selectthe optimal procession parameter and optimal procession ,considering environmentalactor ,mechanic erect kiln is the best one among the different kilns.the procession of closed-loop recyclable concrete is introduced in detail ,we found it is possible to make full use ofwasted concrete illimitedly by proper design ,though the recyclable concrete physicalfunction decreased a little comparing with virgin concrete, it's environmental property ismuch better than usual concrete.we also found that it is possible to use wasted concrete asthe coarse aggregate or fine aggregate.we probe the possiblity that fuzzy mathematics isused to judge whether a product is green product or not.

确定了不同窑型的最佳的工艺操作参数；比较了不同窑型的环境性能，得出结论：预分解窑是最佳的工艺选择。本软件具有专家系统的功能，本软件的最大特点是动态性和灵活性，这是为人为的因素，地方的因素变化性而设计的。允许输入不同的边界条件，即可得到不同的结果，这为水泥-混凝土的环境化设计提供了有力的帮助。本人也努力设计一个适用于水泥厂的数据库的框架，来实现水泥厂的在线评估。本文探讨了实现环境化设计的可再循环的混凝土的设计，得出结论：通过合理设计的混凝土的无限循环是可能的，虽然再循环的混凝土的性能与原混凝土相比有所下降，但其环境性能是普通混凝土无法比拟的，本文还探讨了废混凝土的利用的可能性及评估，废混凝土用作混凝土的粗集料是合适的，虽也可作细集料，但不值得提倡。

Firstly, achieving a new low and high cycle noninterfering loading, the high frequency induction local heating, the control of high cycle vibration frequency and amplitude, and the crack propagation real-time detection, an experimental system of L-HCCF at elevated temperature is established. Secondly, under two vibration frequency (50Hz and 100Hz), the contrast experiment of light and serious corrosion disc slots is done. It is found that the experimental L-HCCF life of serious corrosion disc is less than that of light's, but its dispersion is larger, and the experimental failure is identical with the service's.

首先，进行大量试验工作，提出了高低周疲劳载荷的新型加载方案，并解决了高频感应局部加温、振动调频及裂纹实时监测等多个技术难点，建立了涡轮盘全尺寸高温复合疲劳试验系统；验证试验做到了故障再现；接着进行了两种频比（振频50HZ与100HZ）的轻、重腐蚀盘的对比试验；由对榫槽第一齿进行裂纹实时跟踪，得出了枞树型榫槽的复合疲劳裂纹扩展特点规律；对榫齿断口进行的金相分析表明：裂纹首先由第一齿开始，断口系复合疲劳；试验结果显示：重腐蚀盘试验寿命较轻腐蚀盘有显著的下降，而且分散性较大。
