In this study, from the point of view of the ecological environment of the modern rural analysis and research on rural, ecological environment as the research object,Research programs under the overall guidance of the sustainable development strategy, the Anxin county Liulizhuang Town DongBaiZhuangBeiDui village and environmental symbiosis, in harmony with the natural the rural ecological landscape method. And to strengthen the sustainable development of the ecological environment of the Anxin county Liulizhuang Town DongBaiZhuangBeiDui village, urban and rural, regional development, and comprehensively promote the construction of a new socialist countryside and build a resource-saving, environment-friendly harmonious society to provide certain theory reference.

In this paper, the effect of residual chlorine of hypochlorite (H) on high yield pulping with H2O2/CoSO4of wet stored bagasse was studied. Compared with control sample, the pulp of the bagasse wetstored with H or Ho (without residual chlorine) bleaching waste water had better pulping yield and strength, but the pulp optical property was lost seriously. If it had no requirement on the brightness, the wet storage with H or Ho bleaching waste water was a good method to improve the pulp strength and save clean water. In addition, the wet storage of bagasse using the H bleaching waste water without residual chlorine, the pulping properties was more stable than that of the wet storage using H bleaching waste water with residual chlorine. To the wetstorage with Ho bleaching waste water, the ideal treatment time was 16day.

Effects of deformation temperature and strain rate on deformation behavior of semi-solid ZL201 alloy were investigated on Gleeble3800 thermal-mechanical simulator. On basis of the experimental data of semi-solid ZL201, a model of was established to describe the relationship between the processing parameters and flow stress, which showed that the experimental results and calculation ones fitted well. The suitable conditions of this model for semi-solid ZL201 alloy were that the temperature range was 547°C-649°C and that of the strain rate was 0.1 s-1-5s-1.

Parameters of Bingham model had been verified according to the thermal simulation compression tests of semi-solid 6061 aluminum and the equations presented by Stefan. The effects of the mold filling temperature of semi-solid slurry of 6061 aluminum during thixo-diecasting were analyzed. The results showed that such conditions of the mold filling temperature about 625°C, the injection speed changing to 2 m/s from 0.4 m/s when 60% of die cavity had been filled, were ideal to gain solidification in sequence and beneficial to get fully filled semi-solid parts with clear contour. The thixo-diecasting experiments were performed under above optimized conditions.

Combined with the homogenization method and the least squares method, the filter function with the form of power function is studied in the Independent Continuum Map (ICM) method. Then, the numerical simulation method is used to study the relationship between a weight filter function and a stiffness filter function. Finally, the impact of the filtration function on the efficiency of topology optimization is showed by examples. It is important to further research structural topology optimization.
