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。

Based on the dynamical system of a tuberculosis spread m odel, the dynamical behavior of a tuberculosis spread model with constant immigr ation was discussed, and the local and global asymptotic stability of the endemi c equilibrium on this model is studied by using Hurwitz criterion and multiple m atrix theory. Sufficient conditions for the local and global asymptotically stab ility of the endemic equilibrium on this model are obtained.

Driven by commercial interests, mass media has, by utilizing its right to speech in public domains, mythicized football, a widely influential mass cultural form, and turned football into the main body of mass media for spreading sports information, which has resulted in the deprivation of the right of sports audience to enjoy multi-element sports information, and the distortion of the sports communication behavior of mass media under the guidance of commercial logic, and has done a certain degree of harm to the healthy development of the sports un-dertaking.

摘 要：大众媒介在商业利益的驱动下利用其在公共领域内的话语权，将足球这一影响广泛的大众文化形式神话化，使其成为大众媒介体育信息传播的主体，导致体育受众享受多元体育信息的权利被剥夺，同时也使得大众媒介的体育传播行为在商业逻辑的主导下发生了畸变，给体育事业的健康发展造成了一定程度的危害

Media publicity should be noted is that the rural market in addition to television, very few of the universality of the media, publicity before many companies, some newspapers are self-made types of publicity materials, the production of rough, the credibility of the content is not high, motorcycle No need to blindly follow the industry, as is the motor of consumer durables, its direct customers and potential customers is relatively easy to distinguish between them, these groups can be targeted, but also the reliability of the media; and distributors and sales on the recommendation Relatively easy, as long as some benefit can be tied up; store the image of the more important because the store represents the company's image, the size and strength, a good image to give customers a more credible feel; spread word-of-mouth is an important part of it is With the focus on the need to build into the area because of good service is both a publicity generated by word-of-mouth is a source of Haier's reputation is well-made use of services.

媒体宣传要注意的是，农村市场除了电视之外，很少有普遍性的媒体，以前许多公司宣传时，都自制一些报纸类的宣传品，其制作粗糙，内容可信度不高，摩托车行业大可不必盲目仿效，因为摩托是耐用消费品，其直接消费群与潜在消费群相对容易分辨出来，针对这些群体完全可以进行有针对性、更可靠性的媒体传播；而经销商和营业员的推荐相对容易，只要进行一些利益捆绑即可；专卖店的形象比较重要，因为专卖店代表了公司的形象、规模与实力，良好的形象给予顾客更可信的感觉；服务是口碑传播的重要一环，是需要重点投入与打造的方面，因为良好的服务既是一种宣传，亦是口碑产生的源泉，海尔良好的口碑就是利用服务制造的。
