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 time-domain response of the induced currents on a scattering object irradiated by a plane wave with a Gaussian pulse in time is expanded as an associate Hermite series in this paper. Using the isomorphism of the associate Hermite function and its Fourier transform, the frequency-domain information can be obtained similarly to the time-domain expansion. According to the corresponding relation between time-domain analysis and frequency-domain analysis, and using the early-time response and the low-frequency information of the induced currents, the non-known coefficients in the expansion series can be decided. The entire responses of the induced currents on the scattering object in both time and frequency domains can be obtained at one time by simultaneous extrapolation computation using both the early-time response and the low-frequency information of the induced currents.

摘要首先根据散射体在高斯脉冲平面波激励下感应电流的能量几乎全部集中在时间轴和频率轴上的有限范围内，该文将时域响应展开为系数待定的连带Hermite级数的叠加，并根据连带Hermite函数的傅里叶变换的自反性，得到与时域响应形式类似的频域响应；然后利用时域方法和频域方法分别计算散射体上感应电流的早时响应和低频信息；最后经过时域和频域联合外推计算，由早时响应和低频信息确定时域和频域响应的待定系数，从而获得了整个时域和频域的完全响应。

In 2001, a game renounced the world splendidly, it called " the anti-terrorism elite ", played with the dementia of the family to pursue the intensity and can be described with fieriness at that time, all nearly of Internet caves set up this fund game inside extremely short time, even it is can getting more exaggerative at all say all computer of the whole country, install or now install by anti-terrorism elite still for more than 95 of one hundred copies at least, the streets and lanes are packed with the fierce gunplay sound at one time, the players are discussing the same topic unanimously --Get rid of the rifle, blind Ju, running in the location, clicking killing, trajectory,etc..

2001年，一款游戏横空出世，它叫《反恐精英》，当时玩家的疯狂追捧程度可以用白热化来形容，所有网吧几乎都在极短的时间里面安上了这款游戏，甚至可以毫不夸张的说，全国的所有电脑，起码有百份之九十五以上安装过或者现在仍然安装着反恐精英，一时间大街小巷充斥着激烈的枪战声，玩家们异口同声地讨论着同样的话题--甩枪、盲狙、跑位、点杀、弹道等等。

. It seems to have been at one time at Caesarea; one of the correctors adds this note at the end of Esdras: This codex was compared with a very ancient exemplar which had been corrected by the hand of the holy martyr Pamphilus [d. 309]; which exemplar contained at the end of the subscription in his own hand: 'Taken and corrected according to the Hexapla of Origen: Antonius compared it: I, Pamphilus, corrected it'.

&它似乎一直在同一时间在caesarea ；之一的校正器的加入，这说明，在去年底埃斯德拉斯说：&这是法典相比，一个非常古老的典范，这已得到纠正，由手的圣地烈士pamphilus 四309 〕；表表者，其中载於去年底认购在他自己的手： '采取弥补和纠正的，根据该hexapla的渊源：安相比，它：我pamphilus ，更正的说法。

At one time he puts them in a shorter form or uses more general terms; at another, while adducing in general the same arguments, he adds a new one or omits one or another used in Jude.

在同一时间，他使他们在较短的形式或使用更多的一般条款；另一个，而adducing在一般相同的论点，他增加了新的一个或省略一个或另一个用于在裘德。

For instance when the evicted tenants question, then at its first inception, bulked largely in people's mind though, it goes without saying, not contributing a copper or pinning his faith absolutely to its dictums, some of which wouldn't exactly hold water, he at the outset in principle at all events was in thorough sympathy with peasant possession as voicing the trend of modern opinion (a partiality, however, which, realising his mistake, he was subsequently partially cured of) and even was twitted with going a step farther than Michael Davitt in the striking views he at one time inculcated as a backtothelander, which was one reason he strongly resented the innuendo put upon him in so barefaced a fashion by our friend at the gathering of the clans in Barney Kiernan's so that he, though often considerably misunderstood and the least pugnacious of mortals, be it repeated, departed from his customary habit to give him one in the gizzard though, so far as politics themselves were concerned, he was only too conscious of the casualties invariably resulting from propaganda and displays of mutual animosity and the misery and suffering it entailed as a foregone conclusion on fine young fellows, chiefly, destruction of the fittest, in a word.

比方说，佃户被迫退租的问题当时刚刚冒头，引起民众极大的关注。不用说，他本人连分文也不曾捐赠给这一运动，而且其纲领也并非完全没有漏洞。他不能把信念绝对地寄托在上面。他认为佃户拥有耕作权符合当代舆论的趋势，起初作为一种主义他全面地赞成；及至发现弄错了，就部分地纠正了自己的偏见。由于他竟然比到处游说耕者应有其田的迈克尔。达维特的过激意见甚至还进了一步，从而遭到嘲笑。正因为如此，当这帮人聚在巴尼。基尔南酒馆露骨地讽刺他时，他才那么强烈地感到愤慨。尽管他经常遭到严重的误解，再重复一遍，他仍不失为最不喜欢吵架的人。然而他却一反平素的习惯，朝着对方的肚子给了一拳。就政治而言，他对双方相互充满敌意的宣传与招摇所必然导致的伤害事件及其不可避免的结果——主要是给优秀青年带来不幸与苦恼——一句话，对适者灭亡的原则理解得再透彻不过

At one time Likewise, most gas stations in Thailand at one time gave free washcloths with a gas fill-up.

Here's how it works: instead of starting with your cardio, then working your different body parts one at a time like most long workouts, I stack them, so you get your fat-burning cardio, total-body toning and sculpting, and abs workouts at the same timeΓ??

以下是如何工作的：不是你的心开始，然后是工作在最喜欢的训练时间长的不同部位之一，我堆栈给他们，使您得到您的脂肪燃烧心脏，全身色调和造型，和ABS在训练同样timeΓ？

But we don't care about Battlegrounds.

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
