This paper combines with pipeline delivery of our countrys actual conditions and other methods of detection and location. To the leakage characteristic of the fault to the long-distance natural gas pipeline, a method is raised, which is on the basis of wavelet and negative-pressure-wave to detect the leakage and locate. Jobs in this paper are as follows:Multi-resolution decomposition and reconstruction of wavelet transform is utilized to filter the noises, which the leakage brings the noises of negative-pressure-wave. The research is worked in the wavelet and wavelet packet filter. The wavelet transform have a fast and accurate recognition capability to signal singularity. This paper chooses wavelet technology to catch the break point of pressure signal.

Secondly, in terms of the dynamic development of harmony in chorus, this paper expounds harmony in chorus in different periods in the history of music: harmony in the structure of contrapuntus in the Renaissance chorus, harmony in contra-structure in Baroque chorus, harmony in chorus of the classical period, harmony in chromaticism the expansion of modes in the romantic period. These dynamic features of harmony display the principle of formal beauty in western chorus.

In this paper, three methods for color image retrieval have been presented: hypercomplex SVD image retrieval, combination of hypercomplex convolution filter and hypercomplex SVD image retrieval and hypercomplex matrix correlation image retrieval. We made comparison among these hypercomplex-methods, and compared them with the traditional image retrieval methods. Experiment results showed that the hypercomplex-methods we presented in this paper could well conquer the problems existed in traditional image retrieval methods, and their retrieval results are much better. Meanwhile, this paper presented a new color image quality assessment based on hypercomplex SVD. It is a novel color image quality assessment that can be used as a graphical or a scalar measure to predict the distortion introduced by a wide range of noise sources. It reliably measures the distortion not only within a distortion type at different distortion levels, but also across different distortion types.

The monosaccharides in LBP-4 identified by GC were xylose , galactose , mannose , Rhamnose , glucose and arabinose with the molar ratio of 4. 45: 1. 20: 1. 0: 0.98: 0.90: 0.85. The content of calcium, magnesium, zinc and iron in LBP-4a were 127. 9070mg·g〓, 32. 3953mg·g〓, 0.3845mg·g〓 and 0.2930mg·g〓, respectively. The content of galacturnic acid in LBP-4a was 55. 45% while the content of protein is 3. 80%. According to IR spectra, it contains -COOH group,-NH- roup,-OH group,-NH〓 group and β-D-glucose. The backbone of sugar residues chain in LBP-4a were contained 1→6 indican bond according to periodate oxidation and the results of β-elimination reaction indicated that the chain of polysaccharides and protein were connected by O-linked chemical bond. The photograph of LBP-4a got by laser scanning confocal microscope and scanning electron microscope showed that the LBP-4a combined both with each other and with itself in its crystalloid. The crystalloid was flake and anisotropic.
