This paper mainly introduces the origins, basic structures and family members of carbon, the focus is a new generation of nanomaterial－graphene. In the experiment, a series of tests are taking place firstly, such as SEM, TEM, XRD, XPS, BET, Infrared spectrum, Raman spectrum and Laser particle size analysis. The results show that the graphene has excellent mechanical properties, optical performance, electrical properties and conductive properties. Especially super conducting properties of graphene. Then the basic principle of electromagnetic shielding effectiveness, test methods and condition analysis are analyzed in this paper.

In this paper, the comprehensive property of shielding fabrics was analyzed by the mathematic method-grey cluster analysis. Eight samples of shielding fabrics were selected as research objects in the experiment. The electromagnetic shielding effectiveness in different frequencies and wearing comfort, including tensile and bending property, abrasive resistance, permeability and color fastness were measured and then analyzed. Grey cluster analysis was carried out to evaluate the comprehensive property of the chosen samples by eight clustering objects and nine clustering indexes. In the process of data operation, MATLAB7.0 was used to calculate experimental results due to its high efficiency and accuracy. According to cluster analysis results, the eight samples were divided into three gray classes, namely, 2#, 5# belonging to “first-rate”, 4# and 7# belonging to “medium” and 1#, 3#, 6#,8# belonging to “low-rate”.

In this paper, the artificial compound eye vision system is used to develop an effective algorithm for acquiring 3D information of object. According to compound eye vision system constructed, the imaging principle and correlation between the object point and the imaging point is analyzed. Then the cross correlation matching algorithm is present to extract the depth and obtain the 3D information. The influence factors such as number of matched elemental images and matching window size are considered and analyzed. The experimental is implemented to verify the validity of the proposed method.

Image stereo correspondence is the core technology of stereo vision. It has been widely studied and applied in the fields such as 3D reconstruction, vision measurement and target recognition. According to characteristics and application of stereo matching technology, the image stereo correspondence methods can be classified into three categories: local stereo correspondence, global stereo correspondence and semi-global stereo correspondence. Some image stereo correspondence solutions and problems are emphatically analyzed. Finally some future research issues on image stereo correspondence are highlighted.

This article mainly expounds that deepening of teaching reform in higher education and improvement of personnel training quality are important initiatives to strengthen the quality of higher education connotation construction, to improve students' practical and innovative ability, and to satisfy people in the new period. By being effectively consistent with social needs, mechanical major is more closely combined with mechanical engineering characteristics which meet the diverse demand of engineering talents. Cultivating project suitable to diversification of innovation talents is revised. Curriculum group and practical teaching system of creation and execution in parallel are established. We adhere to the people-centered notion and set ability training as the core, quality as the goal, the accumulation of knowledge as the basis to enhance the innovative ability of college students of mechanical engineering steadily.

Dye-Sensitized Solar Cell (DSSC) is noticed to be proper for BIPV for cheaper, more transparent, and able to realizevarious colored. Researchers constantly strive to improve the power conversion efficiency of DSSCs for this cell’s practicability by doping TiO2Subscript text with inorganic substance, metal ions, or processed with organic, as TiO2 electrode is the core of DSSC to generate photovoltage effection. Here reported a method to determine the optimal La3+ doping proportion of TiO2 by the equivalent circuit parameters estimated corresponds to the reported experment I-V curve. Thus, the concentration of La3+ doped TiO2 thin films of 0.5% of DSSC can get the most out of the photoelectric conversion efficiency.

The way to determine the optimal solids content of TiO2 in DSSC working electrode was discussed. As a mathematical proof of the optimal conclusion extracting from the complex working mechanism of DSSCs and accidental factors, the equivalent circuit parameters of each curve are estimated corresponds to the equivalent circuit method first. And then, the trends in each parameter are analyzed. According to these trends, the optimal solids content of TiO2 are optimal identified

In order to more precisely segment complex microscopic cell image, a new image segmentation method by combination of coarse segmentation and fine segmentation is proposed. Firstly, the coutourlet transform and morphology are used to segment original image coarsely and get the subimages that include the particles. Then ,the Level Set method is employed to locate edge of the particles precisely. The method provides more accurate data for complex microscopic cell automatic recognition system. Taking example for complex urinary sediment image, the experiment results show that the method can segment urinary sediment images effectively and precisely and increasing the performance of urinary sediment particles recognition.

Image compression is a technology using as little as possible bits to represent the original image. As wavelet transform has local characteristics on the time and frequency domain, it makes up the deficiency of DCT. Moreover, its multi-resolution characteristics can easily associate with the human visual system (HVS). Besides, wavelet-based image compression is prone to combine with new image coding methods. It has become the research hotspots at present. This paper introduces wavelets theory and discusses the research status and progress of wavelet-based image compression then points out the main problems. Finally, the prospect in the future was presented.

With the help of IGES standard file which was the exchange specification of initial graphics, different CAD system could change the data of product by neutral file’s format conversing. The automatic generation of 3D-Model curve surface in the MCNP input file was realized by using VC++ language.This method has solved the problem of the complication of MCNP geometric modeling process and the 3D-Model input problem in the MCNP. The input of MCNP was transferred the application problem of CAD/CAM software. The data and figure of varies software could be shared and converted. The work of design could be simple, the process of design could be speeded up and the cycle of design was shorted. Work efficiency and practicability were improved. If precision was controlled in 3D-Model, the result could be expected by contrast.
