To improve the economic benefits of the production of ceramic enterprises, and the research results will be widely applied in industrial production for the purpose of guiding ceramic.

Abstract: Since the success of drilling wood to make fire was achieved by human for the first time, the history of tens of thousands of years had passed over. In such a long period of time, the ceramic culture was created by Chinese people with their own wisdom and hands. In the modern times, the age of the information economy, which has attained a rapid development, has brought about a new, important, and different beginning to human beings. Along with the arrival of the comprehensive cultural age in which natural science is mutually colliding with humanism science, technology and art, thinking in images, and rational thinking, etc. In the meantime, the pursuit of people in beautiful things is developing, and also their consciousness in aesthetics is continuously improved. Modern ceramic art is a demand of human on civilization, but also one of the most important components of the history of art. Besides, modern ceramic art has been accepted by modern people in a certain space environment with great willingness, and also are more appropriate to the needs of modern people, because it owns many characteristics and advantages. For this reason, the combination of modern ceramic art with outdoor environment has a bright and roomy bright prospect in future de-velopment.

Abstract: Along with the development of economy and the improvement of the people’s living standard, the requirements of people on the ceramic products have been proven to be increasingly higher, but simultaneously the pressure on the ceramic industry is greatly increased. On the basis of the development of the ceramic industry, it is necessary to pay attention to the real life, absorb the new thoughts, new ideas, and new techniques of the high technologies of the modern times, follow the road of combining the modern science and technology, and ultimately create a new pattern for the ceramic industry.

Abstract: Whether the resin canals of Cedrus deodara are caused by injuries is still controversial. In this paper, with the branches and trunks of Cedrus deodara taken as research objects, the resin canals in the phloem and xylem of Cedrus deodara are quantitatively and qualitatively analyzed and researched with the principles of wood science, aiming at exploring whether its distribution provided with regularity. The results showed that several parts showed relative stability, such as the morphological characteristics, anatomical structure, occurrence time, cellular component and quantitative characteristics and so on. In terms of occurrence probability and quantities, the resin canals generally occurred in the compression and lateral zones of branches while few in the opposite zone; the occurrence of the resin canals of trunks had an extremely close tie with the growth and insertion angle/direction of the branches of different areas and directions, etc. Therefore, from the perspective of formation time, Cedrus deodara belongs to the tree species with slowly-formed resin canals.

Abstract: This paper sets forth from the effect analysis of the concrete raw materials and all kinds of the performance index tests. It makes further research and exploration of the mix proportion design of P (AA-co-MA)/PEG polycarboxylic copolymer and high performance concrete with composite admixture, combining the mixture of the high performance concrete as well as the performances such as the workability, the hardness of the cement setting and hardening and the endurance quality. It is found that mixing 1.46% P (AA-co-MA)/PEG polycarboxylic copolymer, 15% fly ash and 10% granulated blast furnace slag powder together and adding the mixture into the concrete can not only save the cement but also improve the performance of the concrete. The designed C30 mix propor-tion design of P (AA-co-MA)/PEG polycarboxylic copolymer and high performance concrete with composite admixture has been applied successfully in the high-rise building construction.

Abstract: This paper explains how to make ferrimagnetic ferrofluid r-Fe₂O₃ with chemical precipitation. First, ferrimagnetic nanoparticle r-Fe₂O₃ is produced with chemical coprecipitation. Then, the ferrofluid r-Fe₂O₃ is synthesized by Massart method. Without magnetic field, the interaction energy of two r-Fe₂O₃particles is about 1.92×10-19J, which is more than heat energy and is easy to form a reunion. There exist ring-like structure in ferrofluidr-Fe₂O₃, which has no contribution to the saturation magnetization. The saturation magnetization is less than the theoretical value. The bigger the volume fraction, the more self-assembly ring structure, the less possible it is to crack in the process of dilution and magnetization.

Abstract: With the development of theory that research on Magneto-Rheological Fluids (MRF), the MRF have been used in many fields in our life. The electrical characteristics of MRF can be widely used in automatic control, medical, automotive, aircraft manufacturing and many other areas .Firstly, this article have derived the formula of MRF between capacitance and Dielectric constant, made the Capacitors which can load the MRF. And then we measure the change of capacitance which is filled with the MRF when the time of magnetic field change, And we also measure the sensitivity of the dielectric constant of different concentrations of MRF as the magnetic field changes. And at last, we have made the curve of the capacitance - magnetic induction intensity the experimental results have been analyzed. We have the conclusion that when the magnetic field increases, the dielectric constant is also increases, resulting in increased capacitance of the conclusions of MRF. Introduction

Abstract: Effect of different strain rate on mechanical properties and microstructures of Fe-Mn-C twip steel were studied by dynamic compressed using Gleeble 3500 at room temperature. The results show that Rm and Rp0.2 gradually increase with the strain rate increasing, and the TWIP steel has a strong strain rate effect; The curves of strain hardening rate and true strain have different stage with different strain rate; The mechanism of the deformation behavior was also investigated, it was found that the evolution of microstructure was controlled by dislocation and deformation twins, but the density of dislocation and the appearance of twins were different with increasing strain rate.

Abstract: This paper has made a study on Mechanical Property of SiC particulate reinforced Magnesium Matrix Composites prepared by Powder Metallurgy.In this paper, powder metallurgy was adopted in the preparation of AZ91 magnesium alloy and magnesium-base composite material alloying two kinds of SiC particle, whose mean diameters were 18μm and 8μm respectively. The mechanical properties of the sample such as hardness, strength of extension and coefficient of friction were tested, while microstructure of material was observed in electron microscope. At last, analysis of the friction and abrasion mode and tensile break mechanism of the material were carried out. By the series of trials, the following result can be concluded: the additions of SiC particle can decrease theβ-Mg17Al12 mesh effectively while increase the degree of densifying. Comparing with AZ91, the addition of SiC particle of diameter 18μm and 8μm increase the material hardness by 6.85% and 26.92%, strength of extension 29.14% and 71.38% and coefficient of friction 2.33% and 9.62%, respectively. Magnesium matrix composites that prepared by powder metallurgy can be used for the production of friction materials.

Abstract: In the traditional magnetic separation in dry conditions of magnetic filter jams caused by the efficiency of the machining decline. In order to solve this problem, filter arrangement in magnetic separation. Jam magnetic filter is success in reducing the through the use of prismatic-shaped filter. In addition, the separation effect of prismatic-shaped filters is added as high as, mesh filters used for high system routine.
