Abstract: Noise not only makes people worry, sleep disturbance, hinder learning to work and rest, affect human health, and it is difficult to completely eliminate. Sound barrier is located in the sound source and the sound receiving point between the structure with shielding enough surface density of sound, built finite noise barrier of sound source by both local area can make the operation noise source in the dissemination process has a significant additional attenuation, which weakens the noise influence in certain areas where the recipient within, to improve the quality of acoustic environment of the surrounding environment. The present research situation of new sound barrier and the research content of new sound barrier are summarized. The theoretical reference for the further development of new sound barrier is provided.

Abstract: A field survey in Shandong peninsula in China has been done on rural houses to obtain thermal adaptability model which is expressed as T_n=0.268T_out,m+20.356.An analysis has been done on local climate data by using climate analysis method combined with psychrometric chart,and establish comfort zones of two seasons of winter and summer inWeifang. In this paper, we defined six controlling potential areas (tranditonal heating, passive solar, heat storageand night ventilation, natural ventilation ,air conditioning and evaporative cooling). Finally, this paper summarized the suitable design strategies which response to climate environment on rural houses in Shandong peninsul in China.

Abstract: Qinghai-Tibet region has abundant solar energy resources. The photovoltaic power generation can be utilized to solve the electricity-supply problem in most parts of the region having no access to electricity. General household photovoltaic power can solve the basic problem of electrical lighting, but in some cases where large-power electricity supply is needed, such power cannot be utilized, which means its scope of application is limited. We employ the STM32 intelligent microprocessor controlling method to collect parameters and features of storage batteries and photovoltaic modules. The system can automatically expand capacity and output power, which is very practical in making general household photovoltaic power more widely applied.

Abstract: In order to estimate the state of health (SOH) of each cell in the battery pack, polarization resistance and ohmic resistance were analyzed in the aging process of the battery pack. Accelerating aging test for the battery was done, quantitative relationship between the ohmic resistance and the capacity aging was obtained, a method of relative state of health (RSOH) evaluation was proposed accordingly, Experiments on the LiFePO4 battery pack which is connected in series by 100 cells have been taken, the experimental results show that the evaluation method of RSOH can evaluate the cells SOH accurately and is not limited by the operating conditions.

Abstract: Abstract. Hybrid electric vehicle adopt hybrid electric power, can reduce the waster emission and energy consumption, which can solve the present problem of environmental pollution and energy consume. New type HEV based on composite electric power is proposed.To improve the performance of the system, Halbach PMSM is used instead of traditional PMSM, experimental results show its merits.

Abstract: Dense flow absorber of desulfurization is a new type of semi dry flue gas desulfurization technology, desulfurization of flue gas is mainly in the dense phase absorption tower. By using the turbulence model in Fluent.14 software, three-dimensional numerical simulation of dense phase in different flue gas entrance tower height of internal flow field. Selection of k- ε model as the calculation model, using Simple algorithm. Selected from the flue gas 1m, 2mand 3m, simulation the flow field distribution, combined with the experimental analysis.The results show that the flue gas entrance height from the top of the 1m, the flow field distribution is uniform, the minimum pressure drop.

Abstract: In the High-rise building construction, the selection, combination and optimization of top-down method have not been systematized to date and rely on experience and appraisal. In this article, four classes of parameters are selected according to the different nature of the factors influencing the design of top-down method so as to conduct systematized reorganization and analysis of the geological situation, structural characteristics, construction quality and term, and economic efficiency of the building. This study proposes several tables classifying the influencing factor, establishes selection criteria and suggests detailed flowchart for the planning of top-down method. Case study confirms the suitability of the resulting top-down method planning, and derives and combines the optimized method to provide fast construction.

Abstract: In order to make the functions of intelligent building security systems meet the need of users,enhance the core competitiveness of construction enterprises and promote diversification of real estate,study on the importance of the functions of intelligent building security systems with the method of QFD.According to stakeholder theory,investigate and analyze of stakeholder needs in deep,oriented with stakeholder needs,using Quality Function Deployment method (QFD),get each functional assessment index weight score of the design of security system.The higher the score the more important the function is,and more important for stakeholder satisfaction on intelligent building security systems,and more important for entire functional evaluation indicators.

Abstract: Qunkuqiake Region is an important exploration block in Tarim Basin. Donghe Sandstone is the main oil and gas target stratum. In order to reveal the rules of migration of the sand body and predict the favorable reservoir accurately, two high-frequency cycles are identified in Donghe Sandstone each of which consists of rising hemicycle and descending hemicycle, the sedimentary characteristics are analysed within the sequence stratigraphic framework and the barrier bar subfacies are identified beginning with the sedimentary characteristics of glutenite through the study of drilling stratigraphic section using drilling data, well logging data and cores data. This paper has disclosed the transition of the sedimentary environment from barrier-free coast system to barrier coast system during the period from rising hemicycle to descending hemicycle and the planar distribution of sedimentary facies of different high frequency sequence of Donghe Sandstone.

Abstract: In order to deeply analyze the feasibility of the application of building demolition waste on asphalt concrete, pavement performance of asphalt concrete using different content of building demolition waste was analyzed. Results show that: (1) the addition of building demolition waste increases the asphalt-aggregate ratio of asphalt concrete, and the asphalt-aggregate ratio increases 0.25% with the 10% increase of building demolition waste content; (2) the high-temperature stability of asphalt concrete improved significantly with the increase of building demolition waste content; (3) building demolition waste can improve the low-temperature crack resistance of asphalt concrete, and the optimum content is 30%~40%.
