	Abstract:In order to suppress the noise in the magnetic flux leakage, the algorithm considering signal correlation, in which an optimal predictor and an optimal updater were chosen for every sample at all scales according to the magnitude of the correlation coefficient, was proposed. So the wavelets obtained through designing predictor and updater can perfectly fit the local features of signal. The actually processing effect of the simulation and the magnetic flux leakage signal of damage in wire rope show that the proposed method, compared with the classical wavelet, can effectively remove noise in original signal and principally retain the local features of the original signal.

	Abstract:Aimed at the location tracking of locomotives for underground, The main applications of the OpenCV Tracking blobtrack operational framework for the tracking of underground miner's lamp count,to determine the location of locomotive.Based on the underground light on the particular environment, and the case of camera movement, OpenCV provides three detection algorithms are not applicable to it.To this end,adding a custom foreground detection module,using the background subtraction, based on the adjacent frame difference method supplemented by background modeling.Through the use of the dual fixed threshold method,has been got a very good segmenttation results.Then under the Blobtrack module framework,to achieve the rapid and accurate location tracking locomotive effect.

	Abstract:The crude oil unit is the first working unit of crude oil fractionation units in all refinery units. By the theory of fault tree in reliability analysis, this paper set up the fault tree of the crude oil unit in processing heavy oil. The Analysis result based on the fault tree shows that one of the main invalidation reasons that affect the crude oil unit in processing heavy oil is naphthenic acid corrosion. The analysis of the corrosion mechanism and influencing factors has been studied in this paper, including a corrosion experiment research of the corrosion rate of several materials in different temperatures, consistence and velocity. By the experiment, some important data has been recorded. Integrated analysis on the experiment result and the fault tree, it has been found that the factors deeply and directly affects the corrosion rate of the naphthenic acid, such as the temperature, consistence, relatively move speed, material, and so on. And the relationship is a complex nonlinear problem.

	Abstract:The inner hidden water-bearing bodies are the causes of the water disaster in the working face of coalmine. In order to detect the inner water-bearing bodies under the floor of working face, a new DC detecting method, that is, the parallel Bipole-Dipole method was introduced; and in the data interpretation method, this paper provided the Resistivity Computerized Tomography Method to inverse the position of the (simulated) water-bearing bodies. The modeling test in water tank and trial on spot both indicated that it is feasible and valid with the Bipole-Dipole method in detecting the inner water disaster of the working face, and it would be a promising future as its obvious virtue of amplified observation signals and adaptive range.
