At the same time, combining with the actual condition of delivery pipeline of our country and some prevalent leak detection and location methods, this paper raised a method, which is based on wavelet analysis and negative- pressure-wave to detect and locate the leakage. Jobs in the paper are as follows:As affected by gas density, pressure, specific heat and pipe material, the velocity of negative-pressure-wave improved depending on the energy conservation. At one time, taking the affection of velocity of gas flow, the location formula was modified in some degree.When locating the leaks with location formula, the iterative approach algorithm was adopted as a new method to increase the location accuracy level of system.Multi-scale decomposition and reconstruction of wavelet transform is utilized to filter the noise of negative-pressure-wave, which was brought by leakage. With the capacity to detect the signal singularity fast and accurately, wavelet transform was used to catch the break point of pressure signal. The work improved the accuracy of At in location formula, accordingly improved the location accuracy.Wavelet is a suitable tool for signal analysis. The distinct character is that the mother-wavelet is of optional. That means choosing different mother-wavelet will get different analysis result. So we studied how to choose mother-wavelet and its scale for signal singularity detection. The method is to choose a wavelet by regularities of the wavelet and the signal.Finally, a plan, which bases on SCADA system for inspection and detection of natural gas leakage, is proposed in the article.

其中，主要进行了以下几方面的工作：针对泄漏产生的负压波在管道中的传播速度受媒介的密度、压力、比热及材质等因素的影响，而非声波在空气中传播的速度，本文利用能量守恒原理，对其进行了修正；考虑到管内气体流速对压力波速的影响，对原始的负压波定位公式进行了一定程度的改进，并在利用定位公式进行泄漏点定位时采用逐步迭代逼近算法，提高了系统的定位精度；利用小波变换的多分辨率分解和重构技术，对采集到的管道发生泄漏时产生的负压波信号进行了降噪处理；并利用小波变换技术对信号奇异点的快速、准确的识别能力，对经上述消噪后的负压波信号进行了奇异点捕捉，精确捕捉的结果提高了定位公式中上下游站点采集到的负压波奇异点的时间差△t的精度，从而进一步提高了定位的精度；考虑到小波变换是一种基波可变的信号分析工具，也就是说，不同的小波基波对信号分析的结果将有很大差别，这势必影响最终的处理结果，因此，我们又对比分析了本课题中小波基及尺度的选择问题，依据规则性系数相似性原理对母小波的选择进行了探索性研究；最后，还提出了基于SCADA的泄漏检测与定位系统的软件开发构想及系统的嵌入方案。

The following are the expressions for the mean pressure set up at the detection plate and for the time of the signal to progagate from the radiator to the detector:这里是1个公式,省略） where Re is the real part of the expression appearing within the braces, 0 is the density of the medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in the medium, d2 = I +(r/zcos 8, z is the distance between the emitting and receiving plates, B is the angle between the axis of the acoustic channel and the axis of the tube, r = vro/c, v is the flow speed of the fluid, d is the diameter of the pipe, m is the circular frequency, k is the wave number, where a is the radius of the plate (this is taken as the same for the emitting and receiving plates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, and The triple sums in the expressions for N~ and N2 may be neglected if the flow speed is low, since the contributions for these become negligible.

以下的表情为代表的压力设置在检测板甲，手持骑枪和时间的信号 progagate从散热器排出到检测器(这里是1个公式、省略)。在什么地方才是真正的出现在背带，表现为0密度的吗当时的媒介的振幅振动速度、c是声音的速度中、d2 =我+ r / z，8、z是距离的发射和接收板、B之间的角度对声信道和轴轴管，r = vro / c，v的流体的流动速率公式，d 管直径的圆频率，m，凯西是波数公式* n，一个是半径的板(这是作为相同的发射和接收吗为了简单，但板板是毫无困难地讨论不同半径)、镁-，~的振动频率的发光，。总结了三倍的表达方式和N2 ~能忽略的流量速度低，因为这些变得微不足道的贡献。

By harmonizing four factors of TIS, all kinds of medias and communication channels, TV media can get the integrated media effects in which the audience is focus, to enroot TIS into audience' mind.In conclusion, the paper introduced CIS into the TV media image building by the systemic research on Television Media Identity System.

文章摒弃了传统的单一的传播方式，引进了先进的IMC即整合营销传播方式，从TIS的诸要素的整合、传播媒介的整合和传播方式的整合三个方面进行了探讨，得出：无论是哪一种整合，围绕的中心是受众，产生&用一个声音说话&的综合传播效果，电视媒体构建ifs的基本设想让TIS深入人心。

I was told once that few % of world's population has access to the internet, so this "multimedial revolution" isn't something as big as we are told - by media - to think it is have the access to hardware, software and the now-how to create audio and video- artefacts on their own, at their homes. Every one of them has a possibility to try and use his/her personal computer make a sound or create a series of moving pictures, a possibility to express oneself other way than through hard work, family life or contestation of the status quo.

曾经有人跟我说这世界上只有极小百分比的人与网际网路相连结，所以多媒介的影响不如媒体宣染来的夸张，简单的说，只是现下有较多的人运用个人电脑在家创作一些声音或流动的影像，舒发工作压力，话家常，说说生活或对事物的论点吧。

Now Chinese morality of bona fide is not baaed on the absolute market economy and contract and it is a little traditional.so we should cultivate the modern morality of bona fide based on market economy.

现在虽然人们的诚信观念接受了市场经济的冲击和洗礼，但还带有浓重的传统色彩，它还不是完全建立在市场经济之上的，即不是以契约为媒介的，因此。培养以市场经济为基础的诚实信用道德已成为迫在眉睫的事情。

The second chapter probes into the way and feature of spreading on Gesar" s music, and the development and the changes of the music spreading since the involving of modern intermedium, by introducing the psalmodies in different categories. The third chapter analyses the types of Gesar" s lyrics and the patterns they could change. The forth chapter illustrates the principles of Gesar" s creating and several majority tone patterns are showed here. In the fifth chapter, the tones of Gesar are classified based on three aspects, that is, the tone" s name, utilization and the localstyles. In the sixth chapter, the feature of Gesar s tones is analyzed from the aspect of the characteristics of melody, the rhythm and time, the tone patterns and the music structure and so on. The last chapter discusses the forms of music performance and the methods that the psalmodies take to sing.

本文第一章从史诗《格萨尔》说唱结合艺术形式的产生与发展开始，对它的这种艺术形式中的说与唱分别做了介绍；第二章通过对《格萨尔》音乐创作主体——艺人的分类介绍，探讨了史诗音乐的传播方式、传播特点以及在现代传播媒介的介入下它的传播方式的发展与变化；第三章是对唱词体裁的分析和它的变化类型；第四章论述了音乐唱腔的创作原则以及几种最主要的唱腔类型；第五章从曲调的名称、曲调的运用以及地域风格特点三方面对《格萨尔》唱腔进行了分类；第六章结合谱例从旋律特征、节奏节拍、调式以及音乐结构等方面分析了《格萨尔》音乐唱腔的特点；第七章是对《格萨尔》音乐表演形式及艺人演唱方法的探讨。

In A (1991-1992) it is done on classical sculptures, which are the symbol of western culture, to express the cultural conflicts between China and the Western world. In B(1993) it is done on China's political icon MAO to illustrate the crazy worships in the modern China, and in C (1993 to 1996) it is done directly on Fashion model to reflect the current consumption culture,which has pointed out the same things like in the work of Stock Issue,to predict that the pop culture epoch has arrived in China.

整个系列保持了使用国粹——针灸——这一主体媒介的一致性，A部（1991——1992）以象征西方文化的古典雕塑模型为对象，切入中西文化冲突的问题；B部（1993）以毛泽东像的雕塑模型为对象，是针对现代中国的疯狂政治偶像崇拜问题的； C部（1993——1996）直接使用作为时装模特的商品模型，在问题的指向上与1992年的《发行股票》一样联系到了当下的消费文化，提示取代主流精英的市民化审美趣味的时代来临。

The inscribed memory has a negative impact on self-representation of Zhuang. Surely because that Zhuang adheres to the traditional memory transmission way, the inscribed memory is not the only way to transmit memory.

但是，由于壮族族群长期形成的以身体为媒介的传递方式并未因为文字的发明而中断，强势文化对族群的改造被限制在一定的程度和范围之内，壮族的族群记忆虽然产生了局部的偏移，认同感有所减弱，但基本上得到相对完整的延续。

Analyzing the transnational and local men's fashion magazines, we can understand even if the international men's fashion magazine, like GQ, appeared and influenced the local male in a global way. From different cultures, magazine origins and readerships, the local men's fashion magazine still can present some diverse features in many aspects.

而分析跨国与本土的男性时尚杂志则可以看出，在全球化的脉络下，虽然有如同《GQ》此类国际性男性时尚媒介的出现，对本地的男性产生一种全球化的男性气质规训，但随著杂志来源、读者群与当地文化的不同，却也并非如Connell所言，全球的媒体会再现出单一的男性气质形式，本地的男性时尚杂志在许多方面仍呈现一些不同的面貌。
