提出了一种基于支持支持向量机和主成分分析的轴承表面缺陷检测算法，该算法把轴承中的非缺陷区域和缺陷区域分别看作两种不同的纹理模式，先利用主成分分析法对图像进行降维处理，然后用支持向量机方法对降维后的样本采样学习，然后进行分类判断。

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

136 cases of pointed condyloma were treated in the center. The surface of the lesion area was first treated with dichloroacetic acid for 15 minutes, and washed with normal saline, then MEBO was applied to the lesion area. MEBO was applied every 6 to 8 hours(3 to 4 times a day) and 8 cases of the same disease were treated with MEBO 2 times a day(every 12 hours), 3 cases with large lesion areas were treated more frequently.

The samples'concentration level is ng/L, meanwhile, which doesn't go beyond the national standard "Environmental quantity standards for surface water-GB 3838—2002"and "Drinking water quality criteria standard GB5746-85". The study shows that the water purification palnts in The Three Gorges Reservoir Area especially those raw water from Yangtze River and Jialingjia River is safe enough for drinking and its level is low. After having tested and analyzed the raw water samples of 6 water purification plants in Three Gorges Reservoir Area, I have found several variety of PAHs and PAEs. Of which, naphthalene, fluoranthene and DEHP are priority pollutants firstly listed by SEPA..

In this paper,the updated Snake model is used to solve the echocardiography processing.Based on the updated active contour model,the contour points for two-dimensional slice serial of echocardiography are gotten.On this basis,through calculating the distance between the contour points of each two-dimensional slice and the center axis lines,the distance matrix from the four cambers of the ventricle to the center plane of ventricle are gotten.And through interpolating,smooth handling and filtering,the 3D endoscopic surface of ventricle is fitted out.Besides,in the medical measurements field,the slice area of ventricle and the volume of ventricle are measured,and the trend of slice area is also analyzed.

将改进的Snake模型应用于心脏超声波图像处理：基于改进Snake模型的思想，得到了心脏超声波图像二维切片序列的轮廓点，在此基础上，得到分割出的心室上下左右4个曲面上轮廓点到中心平面的距离矩阵，并通过插值和平滑处理以及滤波处理工作，拟合出心室的三维曲面图，取得了较好的效果；在医学测量方面，对心室的切片面积、变化趋势及心室的体积进行了测量。

Based on the analysis on the oil sources and migration pathway of this area, the mineralization modes of the oil sand in the area are derived in this paper. Main conclusions are drawn as follows: a. multiphase tectonic activity resulted in multistage hydrocarbon generation of the source rock; b. threestage tectonic activity and threestage mineralization process formed a great deal of unconformity and fault pathway, thus the crude oil could migrate in a long distance; c. the tectonic activity in Yanshan and Himalayan stages uplifted the edge of the basin and the eroded reservoir outcropped to the surface, the light oil escaped and then the oil sand resource formed; d.

通过对该区油源和运移通道的分析研究，得出该区油砂的成矿模式：①多期的构造活动使烃源岩多期生烃；②三期构造活动、三个阶段的成矿过程，形成了大量的不整合面和断层通道，使原油远距离运移；③燕山期和喜马拉雅期构造活动使盆地边缘抬升，经受剥蚀，油层出露地表，轻质油逸散形成了现今的油砂资源。

During the early stage of Yanshan Movement in the Mesozoic Era, when the North China Plate had completed joining the Yangtze Plate to become a new united Craton massif, the tectonic movement turned to intracontinental orogenic stage, resulting in widespread magmatic activity and migmatization so that Tianzhu granitic batholith intruded the area on a large scale to form an embryo of the granite peak forest in the Tianzhu mountain area and ultrahigh pressure metamorphic zone further retraced its way, and consequently outcropped on the crust surface.
