Abstract: The evaluation model for horizontal well development has significant potential in recoverable reserves uncertainty studies. This paper firstly establishes an evaluation model on the degree of reserve recovery at different level of water cut, and then makes a chart of the dimensionless aspect seepage ratio against the degree of reserve recovery at different level of water cut. Secondly, introduces heterogeneity correction factor and saturation correction factor to improve the oil recovery model. Finally, the oil recovery of 6 reservoirs with horizontal well development in Dagang Oil Company indicates that the prediction of the evaluation model is agreement with the actual data, and the model can provide criteria for horizontal well development in a bottom water reservoir.

Abstract: In order to solve the freezing problem associated with the traditional photovoltaic/thermal (PV/T) system, a novel heat pipe-type PV/T (HP-PV/T) system was designed and constructed in the present study. Outdoor tests were carried out from May to July, 2010. The performance of the system was also studied. The results showed that the average photothermal efficiency was 41.30% and the photoelectric efficiency was 9.42%. The average first law efficiency of the system was 48.52%, and the second law efficiency of 6.87%

Abstract: Many people currently ignore the validity of the fact that intangible cultural heritages acting as an objective of intellectual property law, and make exploitation wantonly, which cause intangible cultural heritages to be on the verge of extinction. How to change the status quo has been the most important research topic of common concern in international society. The thesis exerts comparative studies on feasibility of protection on intangible cultural heritages by various kinds of intellectual properties, based on the characteristics of regional-natured, collective-natured, perpetual-natured, etc. owned by intangible cultural heritages. The thesis expounds highly agreement between geographical indications and intangible cultural heritages. With this base point, the thesis puts forward some countermeasures on geographical indications protection on intangible cultural heritages in terms of subjects, objects, and limitations on rights.

Abstract: The thesis analyzes the validity of environmental taxation system construction, from the view angles of control of ecological pollution, increasing the utilization rate of resources and developing green industries. The thesis illustrates the status quo on Chinese environmental taxation system and each field of environmental undertakings. In the end, the thesis puts forward thoughts and proposals for constructing Chinese environmental taxation system covering government, enterprises and the public.

Abstract: Aimed at investigating the design method and test method of jet-mixing apparatus, numerical simulation and experiment research were both used to investigate the internal flow field of jet-mixing apparatus in this article. Numerical simulation scheme for interior flow field of jet-mixing apparatus was established, CFD software Fluent was used to investigate in concentration field of jet-mixing apparatus. The concept of IOS was brought forward to evaluate the homogeneity degree of pesticide and water. Investigation both carried on area ratio effect on the mix homogeneity of the jet-mixing apparatus and the distribution of pesticide concentration in the axial and radial of mixing tube.

Abstract: This paper introduces a kind of ENMS system based on GPRS, according to the technical requirements for meter reading systems of residential area. It enables remote meter reading of residential area. In this article network diagram is Shown and the block diagram of meter reading management center and the main functions are explained. Compared with traditional implementations, the communication of the program design has obvious advantages.

Abstract: This paper aims to account for sustainable development of different cultures in the context of globalization from the perspective of cultural functions of translation, which wield enormous power in constructing representations of the foreign culture and have far reaching effects in the target culture. According to cultural communication of translation, the major task of translation is to turn the cultural information in one language into another. Therefore, in the process of translating, the translator should try his utmost to allow his target language reader to acquire cultural information of the source text in order to promote mutual understanding between Western people and Eastern people and make different cultures co-exist peacefully and achieve sustainable development.

Abstract: Catalysts based on hydrotalcite-like precursors (Mg-Fe and Mg-Al-Fe) were synthesized by a co-precipitation method. The precursors and catalysts were characterised by XRD, TG, nitrogen physisorption, H2-TPR and Raman spectroscopy. The mixed oxides were applied in ethylbenzene dehydrogenation with CO₂ and Mg-Al-Fe catalyst had better activity and stability. The improvement of Mg-Al-Fe in activities can be attributed to the better textural property and reduction property. There are two type of coke deposite on the catalysts and more coke deposit on Mg-Al-Fe catalyst.

Abstract: Rainfall infiltration and reservoir water level fluctuation are major factors inducing slope deformation. Taking nearly three years data of Bazimen landslide in the Three Gorges Reservoir area and basing on the mathematical regression analysis method, a mathematical relationship among landslide deformation, water level and rainfall is established. And then the most adverse condition under the superposi¬tion of rainfall and reservoir water level is obtained.

Abstract: Three-dimensional-electrode electro-Fenton is a newly electrochemical oxidation technology to treat landfill leachate. In contrast, the removal efficiencies of COD and color in DSA system are obviously higher than those in iron anode system and the organics can be degraded more thoroughly. Under the optimal operating conditions, the removal efficiencies of COD, NH3-N and color in landfill leachate by DSA system are up to 80.8% ,55.2% and 98.6％. Besides, the reaction mechanism of three-dimensional-electrode electro-Fenton is also discussed.
