Beijing's housing prices are too high, some of the geographic location will be 7000 yuan per square meter or so, imagine if people have bought a 100 square meter house, that is 7,000,000,000 yuan, so if the 8 commercial loans into 15-year mortgages, interest-ray will be paid in vain Bank of more than 10 million, 700,000-wide section of the house really had to own hands has become more than 800,000 million, the property is added the costs, heating costs, parking fees, and so a lot of costs, and continue to listen to the people around said, and so on After a 2008 house prices may fall.

北京现在的房价太高，地理位置好些的每平米就要7000元左右，试想如果买一套100平米房子，就是700000万元，如果做8成商业贷款15年按揭，光利息就要白白交银行10多万，全款700000的房子真正到了自己手里就成了800000多万，还得加上物业费、供暖费、车位费等等一大堆费用，而且不断听周围的人说等过了2008年房价有可能会降。

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.
