Abstract: With China's rapid economic development, the construction of a large number of chemical industrial park, And followed by a chemical park brought security issues. Therefore, security planning industrial zone is a very important thing. In this paper, the chemical content of the park's security planning, given a specific solution, and safety planning measures based on scientific research are given, This can make all the security risks chemical park disappear under the bud.

Abstract: The ion-exchanger Mg₂Ti_1.25(PO₄)₃ of spinel type was prepared by means of the solid state reaction crystallization method. Its ion-exchange properties for alkali ions such as saturation capacity of exchange and distribution coefficient were determined. Mg₂Ti_1.25(PO₄)₃ was characterized by virtue of X-ray diffraction method. This inorganic ion-exchanger (Mg₂Ti_1.25(PO₄)₃) has the saturation capacity of exchange for Li⁺ higher than those for other alkali ions, the saturation capacity of exchange for Li⁺ reaches to 6.0mmol/g, MgTi-750(H) has a higher selectivity of ion exchange for Li⁺ than for other alkali ions. These result show MgTi-750 (H) has better memory and selectivity of ion exchange, and higher capacity of ion exchange for Li⁺. It is a kind of prospective ionic sieve for Li⁺.

Abstract: The ion-exchanger Li_0.6Zn_1.2PO₄ of spinel type was prepared by a solid state reaction crystallization method. The extraction/insertion reaction with this material was investigated by X-ray, saturation capacity of exchange, and Kd measurement. The experimental results have proved that the acid-treated sample has a capacity of exchange 2.4mmol•g^-1 for Li⁺ in the solution, The chemical analysis showed that the Li⁺ extraction/insertion progressed mainly by ion-exchange mechanism and surface adsorption.

Abstract: Energy saving always attracts many countries'attentions. Energy saving reform of the existing buildings was accepted in many countries. There are a lot of innovation in energy saving. In this paper, we believe that TRIZ can solve these problems in energy saving. Then, we constructed a model of energy-saving based on TRIZ. This model proposed preliminary solutions by using TRIZ in energy saving. TRIZ will be applied more in this field.

Abstract: Abstract The enrichment ratio of 10B in the top and bottom component with the dynamic change of feed fluctuation and periodic wave on the separation process of the boron isotopes separation by chemical exchange method had been studied and a dynamic model was set up. The results indicate that when the feed amount is in the column load limit, the dynamic responses of top and bottom separation plate match well with the condition when feed flow rate is invariable. While when the exchange column is overloaded, the feed flow rate variation influences ¹⁰B abundance ratio greatly. With the increasing of the fluctuation period, the longer the wave period, the bigger the amplitude around the average line in top product. However, big increase of feed fluctuation will reduce the 10B abundance ratio of bottom product.

Abstract: The paper analyzed some problems of general chemistry teaching in independent college, and pointed that teaching reform should be carried out according to the independent college training goal. Teaching plans should be worked out according to training goal, teaching methods should be reformed, experimental course should be enhanced, general chemistry course should combine with professional feature, contact of the theory and practic should be payed great attention. Through the teaching reform, the general chemistry teaching level of independent college can be enhanced practically.

Abstract: Aim of this study was to detect biocompatibility of the materials of goose-head nail steel plates, so as to evaluate the safety of these kind of materials. We combined sensitization test,intracutaneous irritation test,chromosome aberration test,Ames test and a local reaction test after implantation to evaluate the biocompatibility of the test samples. The results suggest that the test samples have no sensitization, no intracutaneous irritation, no genotoxicity in chromosome aberration test and Ames test. Materials of Goose-head Nail Steel Plates are biologically safe and could be generalized for clinic application.

Abstract: The structure of professional practical ability was analysed, and it was pointed out that the professional practical ability is composed of knowledge, skills and powers to use knowledge and to innovate in technology. The instructional strategies for promoting professional practical ability were investigated. Through organizing the knowledge structure rationally and letting students acquire knowledge by the way of "problem-solving" in classroom, teachers can make students gain the knowledge to be favorable to use. Through teaching students logical thinking method and scientific method, teachers can make students master the thinking methods that are favorable to use knowledge. And through strengthening practical instruction in laboratory and constructing practical platform of college-enterprise cooperation, teachers can make students acquire professional skill.

Abstract: A stable form-phase change materials (PCM), based on capric-lauric acid eutectic served as the absorption material and the support of nano-silica material to prepare by sol-gel method. The best ratio capric-lauric acid eutectic combination is determined for 60 wt. %. Capillarity because of the influence of the hydrogen bonding, fatty acid and eutectic can be fixed in the three dimensional network structure of the construction of the silicon atom bonds and O still so solid sample melting point composite heating more fatty acid eutectic. Form and chemical properties of the composite phase change the transmission electron microscope, semi and Fourier transform infrared method.- Differential scanning calorimetric hot method is used for measuring phase transition temperature and phase change of latent heat composite, value 19.57 and 71.28 J/g , respectively. At the same time, service performance and other composite material thermal stability and thermal conductivity coefficient test using thermo gravimetric analysis and transient hotline method, respectively.

Abstract: Traditional interactive software and its User Interface (UI) have many shortcomings, so it's hard to meet the needs of users. But the new personalized interface model has good expansibility as it's based on XML language. In addition, the separate storage of XML file and executable programs fully realize the separation of application logic and UI.
