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。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.

The basic concepts such as price, value, counting criterion have been discussed, but the discussion is rather from a practical point of view than from the analysis of its essence. There are also discussions on valuation methods, but they are just limited in the specific method used in a singular asset valuation instead of colligating and comparing the methods applied in different kinds of assets valuation.
目前对资产评估理论的研究基本上都局限于在现行资产评估理论框架下的个别问题的探讨,评估界存在对资产评估理论中价格、价值,评估计价标准等基本概念的讨论,但讨论主要从实用角度出发,少有从资产评估理论的本质出发进行分析的;评估界也存在对资产评估方法的讨论,但讨论多仅限于单一资产评估时方法应用本身,没有将方法在各类资产评估时的应用对应起来进行比较、统一。

The major issues in current legislation for minors protection include: 1 Although some laws provide for the protection of lawful rights and interests of minors by institutions and individuals, these provisions only serve as recommendations/advocacies due to the absence of corresponding punishment rules against violators; 2 There are overlaps, duplications and even conflicts between existing laws/regulations on minors protection; 3 Long-term, effective measures are not available for effectively addressing certain concrete issues with regard to minors protection, and linkages are absent when multiple institutions are involved; and 4 Protection of substantial economic interests of minors is inadequate, which is yet to be strengthened in legislation.
目前未成年人保护的立法方面存在的主要问题是:1、《未成年人保护法》及其配套设施缺乏有效对接,对未成年人权利的法律保护不健全或者不匹配。2、对涉嫌违法犯罪的未成年人的相关保护还存在很多欠缺,对涉嫌违法犯罪的未成年人被免于处罚后缺乏后续措施,不能有效防止未成年人重新违法犯罪,对涉嫌违法犯罪的未成年人进行讯问时的法定代理人或监护人在场制度的相关法律规定不统一、不健全,对涉嫌违法犯罪的未成年人适用社区服务令、暂缓判决等处罚形式缺乏相应的国内法依据等。3、对未成年人财产权利的保护还存在不足,需要在立法方面得到加强。

Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.
