原始发生

One day when a modern bottle drop in Kalahari desert accidentally and was picked up by a Bushman Xixo, it became the first evil thing shared by Bushmans and causing unhappiness and conflicts among them at the same time. Therefore Xixo decided to bring it back to the edge of the world. During Xixo's adventurous journey there happened a chain of events, from which we can see the shadows of many things, such as humanity, animals and so on., and feel the fierce contrast beteween original and modern civilizaiton.

一天，当一个现代的瓶子偶然掉落在了卡拉哈里被布希人凯捡到后，它成了布希人第一个共有的引起了他们之间不愉快及矛盾的不祥之物，凯决定把它带到世界尽头丢掉，在凯的旅途中发生了一系列的故事，从中我们可以找到人性、战争、动物等等的影子，可以深刻地感受到原始文明与现代文明的激烈碰撞。

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。

In the broad-leaved Korean pine climax forest, the fine root climax production of the community occurs in July and October, but the dominant arboreal species, understory arboreal species and fine roots of grass have a different production dynamics. It is important to sort the fine root species because accurate fine root production sources have a different fine root dynamics.

在原始阔叶红松林中，群落细根的生长高峰发生在7月和10月，但其中主要树种、其他木本和草本的细根有着不同的生长动态，所以在计算细根生产量时应该分类计算，才会得出较为准确的结果。

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。

Most of non-equilibrium microstructures in the original microstructure dissolve into the α-Mg matrix due to the diffusion of the solute and then the remainder is melted firstly. The more the increasing of cooling rate or pre-deformation, the more the secondary dendrite arms are easy to coarsen.

原始组织中的非平衡共晶组织在加热过程中大部分扩散溶解而溶入基体中，剩余部分在加热过程中首先熔化；冷却速率越大或预变形处理以后的试样在熔化过程中更容易发生二次枝晶臂之间的合并。

ABSTRACT Purpose To investigate in clinicopathological features, histogenesis and biological behavior of primary primitive neuroectodermal tumors of cerebrum and spinal cord.

The results indicate that the flow stress of the alloy increases with increasing strain rate and decreasing deformation temperature. The flow stress increases with increasing strain until the stress reaches the peak value, then the flow stress remains constant, which indicates that dynamic recrystallization happens during deformation. The flow behaviors are described by the hyperbolic sine constitutive equation, and the activation energy calculated is 337.75 kJ/mol. The as-forged microstructure consists of refined α2/γ and γ grains, and the grains are much homogeneous than before. The B2 phase distributes uniformly at the grain boundary of α2/γ and γ grains. The B2 phase decreases with increasing deformation temperature.

结果表明：流变应力随着应变速率提高和变形温度降低而增大；在变形过程中，流变应力随着变形量增大而增大，当流变应力达到峰值后趋于平稳，表明合金在变形过程中发生了动态再结晶；热变形过程的流变应力可采用双曲正弦本构关系来描述，平均激活能为337.75 kJ/mol；从合金的组织演化过程中可以看出，合金中不均匀的原始组织得到明显均匀化，变形后的组织是由α2/γ层片晶团和γ晶粒组成的双态组织，在α2/γ层片晶团和γ晶粒的晶界交界处发现分布均匀的B2相，并且随着变形温度升高B2相数量逐渐减少。

In the New Testament when referring to this incidence in the book of Prophet Isaiah, the Author did not quote the exact number of the Assyrain soldiers as those he mentioned was less than the ones mentioned in the book of Prophet Isaiah and other erros like that including the translator of the various versions of the bible in order to suit their own or dogma even deliberately add or subtract but such addition or subtraction could easily be detected out when compire to the original Greek text from which the bible was originally translated into English and more impotently when compare from the original Hebrew or Aramaic text of the scriptures.
