Abstract: The production of a multilateral horizontal well is higher than the production of a vertical well, even than that of a unilateral horizontal well. Nonetheless, the stimulation effect is significantly influenced by the branch parameters, and the impacts of branch parameters on the productivity of a multilateral horizontal well are rather complex. The interference of the main hole with the branches is the primary factor influencing the stimulation effect of the multilateral horizontal well: the larger the angle-building rate of the branch boreholes, the better the stimulation effect. Therefore, longer branches with fewer branch number or shorter branches with more branch number can be used to optimize the stimulation effect of multilateral horizontal wells.

Abstract: The temperature and humidity independent control air-conditioning system's basic principle and relative equipments was introduced, and it with high energy efficiency and can be driven by low grade heat source. Selects a typical office building located in Beijing as the analysis object. The building annual hourly cooling and moisture loads were calculated by DeST. This system was compared with traditional condensation dehumidification air conditioning system in the COP and the energy saving.

Abstract: Referring to the antifreeze improved test of cement-soil and combining with its own characteristics and functions of the ecological slope protection material, the paper selects palm fiber, silicon powder and surface active agent as the antifreeze raw materials to the ecological slope protection substrate. Based on the method of antifreeze on concrete, through the evaluation of relative dynamic elastic modulus and mass loss rates in the process of freeze-thaw cycles, the results show that the best composite antifreeze to improve the frost resistance property of the ecological slope protection substrate is that palm fiber: silicon powder: surface active agent=1:3:0.05. While the additive amount reaches 1.5% by weight of the dry ecological slope protection substrate, the best effect will be obtained.

Abstract: nstantaneous consumption models are designed to provide an accurate description of fuel consumption by relating the instantaneous rate of consumption with the vehicle acceleration, speed and the engine dynamics. In principle, instantaneous consumption models allow users to calculate the fuel consumption for any profile of vehicle operation. Some kind of models that take into account only driving dynamics can be used to describe the variability of consumption. The procedure used by this type of models is to establish reference matrices (related to specific time intervals) that for each combination of speed and acceleration determine the rate of fuel consumption. This paper Describes the design of a mobile application for the estimation of consumption, and user behavior, that applies models of instantaneous consumption. A preliminary experimental survey has been the carried out to obtain a large data base related to the acquisition of cinematic and engine parameters to allow the development of the mobile application. The experimental acquisition of parameters was accomplished in dynamic driving, connecting the OBDII port to different models of vehicles. With this procedure, reference matrices of fuel consumption for each specific class of emission (as required by ECE 15.03 - Directive 78/665/EEC and ECE 15.04 - Directive 83/351/EEC) have been obtained. The mobile phone application, after receiving as input the vehicle specifications provided by the user, can associate the specified matrix of consumption to the cinematic parameters (instant speed and acceleration obtained by GPS measures) and by using each pair of speed and acceleration can give an estimate of consumption values. At the end of the trip the user can take view of all device information on consumption also by geo-displaying the information on a map (showing the path and the related point by point consumptions). The output of the system, that can also provide information related to the dynamic behaviour and energy management in the user guide style, have been confronted with real consumption data. The advantage of the application is to estimate fuel consumption and driving style, from just GPS data, without connecting the phone to OBDII port.

Abstract: In 110~190°C for 15~75min excess sludge thermal hydrolysis test, investigated the dissolution rate of the volatile suspended solids, Sludge SCOD, TCOD concentration change in composition of organic acids in the supernatant, and analysis the improvement of the anaerobic digestion performance. The results show that, with the increase of thermal hydrolysis temperature and extension of time, sludge supernatant on SCOD, VFA rising. At 190 °C, 75min conditions, SCOD, VFA reached the maximum 6674mg / L2630mg/ L; Sludge organic solids dissolved and the release of COD, etc. mainly in the first 45 min to complete, little change after 45min. When thermal hydrolysis temperature between 90~170°C, anaerobic digestion performance increase with temperature rise, When the temperature is higher than 170 °C, the sludge anaerobic digestion performance begins to decline.

Abstract: With the increasing development of society and the economy, the concept of green construction gradually attracts the much attention, and has been more widely used. In the green construction process, materials and energy-saving is a very important aspect. The rapid development in information technology today, information technology in all walks of life have been fully applied. The digital technology has provided us with the opportunity of a construction design in a virtual environment. This paper first describes the concept of green construction, and then expounds the specific of technology on utilization of green construction material-saving and material resources,through combining with specific examples, expounds the specific benefits of green construction.

Abstract: Research on removing algae in slightly polluted Yellow River water using four combined processes , compared the effect in removing algae of every combined process , It will provide a reference for the profess of treatment drinking water using Yellow River water as headwaters for the future.

Abstract: Coal mining in Shanxi is characterized by the most severe gob and subsidence in China, so its ecological restoration is strongly typical, exemplary and stimulating for the whole country. At present, most of domestic researches focus on land reclamation rather than the ecological restoration of subsidence area for coal mining. In terms of subsidence area, ecological restoration is no longer to simply restore the subsidence area to the available settlement land, but to establish a natural complex ecosystem which is totally or partially different from the function of original land and can be harmoniously integrated with the surrounding economy, society and economics, thus generating high economic, social and environmental benefits. This paper analyzes the specific causes of environmental problems in mining collapse regions, and learns effective and advanced experience to propose techniques and methods for ecological restoration as well as the countermeasures and suggestions.
