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。

With this notion in mild, we can appreciate the importance of maxillary sinus puncture in documenting microbiology of pediatric rhinosinusitis. By this methodology, we demonstrated that α-hemolytic streptococcus, Hemophilus influenzae, Streptococcus pneumonia, coagulase-negative Staphylococcus, and Staphylococcus aureus are the major organisms found in pediatric rhinosinusitis. We also demonstrate a different pattern of antibiotic resistance when comparing to previous studies performed in both children and adults.

Randomly adopted 1000 students from 6 country middle schools and 4 country elementary schools, and get 813 available subjects. We can find that: the percentage of Left-behind children is the largest in the whole children, especially Left-behind children who have only one parent; and mentally healthy situations of Left-behind children are poorer than those who are not, the poorest are children who are looked after by compeers or even no rearings; the situations of children who have been Left-behind children also are not so good, there are significant differences mentally healthy between them and those who have not been, while anxiety scores are only a little lower. And there are differences in sex, grade, quarter, single or not and years parents being out among those who are Left-behind children. There are differences of parenting styles among different styles of children caring. Totally speaking, the scores on positive parenting styles of no left-behind children(such as warmth of father and mother) are higher than those who are and who have been left-behind children, but the scores are obviously lower on negative parenting styles such as punishment from father or intervening punishment from mother. The regression equation of anxiety scores on left-behind children set by parenting styles also depends on children caring styles. Positive parenting behaviors of parents and caring people have positive influences on mentally healthy of children, for instance, some supporting and mood warmth., while some negative behaviors such as rejection have negative influences.

随机抽取了江西省的6所农村中学和4所农村小学，调查学生被试共计1000人，有效被试为813人，对调查数据进行分析后发现：留守儿童所占的比重在全体儿童中最大，尤其是单亲看护人的留守儿童；而且，留守儿童的心理健康状况也显著低于非留守儿童，情况最差的是同辈看护或无看护的留守儿童；曾留守儿童的心理状况也不尽如人意，它与非留守儿童的心理健康差异达到了显著水平，心理焦虑总分只是稍低于留守儿童总体；并且，留守儿童的心理健康同样存在着性别、年级、独生与否、住宿与否以及父母打工年数的差异；不同看护类型的留守儿童父母教养方式存在着差异，总的来说，非留守儿童积极性的教养方式(如父亲温暖、母亲温暖等)得分要高于留守儿童和曾留守的儿童，而在很多消极性的教养方式如父亲惩罚、干涉，母亲干涉惩罚等等上，留守儿童与曾留守儿童的得分又要显著高于非留守儿童；家庭教养方式对留守儿童焦虑总分的回归方程视儿童的看护类型而定，父母和看护人的一些积极性的抚养行为对儿童的心理健康有着积极的影响，比如情感温暖或者支持温暖等，但是一些消极的比如拒绝等对留守儿童的心理健康就有负面的影响。
