摘要：
Red-sandstone reinforced with hexagonal wire mesh is a new concept of composite reinforced soil. In order to study the mechanical properties of this composite reinforced soil, a series of laboratory triaxial compression tests on specimens reinforced with hexagonal wire mesh were carried out. 3D finite element method was introduced to simulate the triaxial tests. The macro stress-strain relation of the red-sandstone specimens reinforced with hexagonal wire mesh inclusions was reproduced and verified by 3D finite element model. The results indicate: finite element method is a ideal technique to study the mechanical characteristics of composite reinforced materials. The peak strength of red-sandstone are increased by hexagonal wire mesh reinforcements, and the peak shear strength arrives at a larger shear displacement than the plain red-sandstone specimen.
摘要：
In order to improve the biodegradability of xanthate, the biodegradation process of butyl xanthate as the sole source of carbon and energy was compared to that with an external carbon source added. The experimental results showed that the degradation rate of xanthate was significantly increased in the co-metabolism process. The biodegradation rate of butyl xanthate was 65.2% after shaking culture for 72 hours under the following conditions: constant temperature of 25°C, external glucose as growth substrate with a concentration of 0.20g/L. While using butyl xanthate as the sole source of carbon and energy, its biodegradation rate was only 43.1%, and there was a 22.1% increase of the degradation rate. So the co-metabolism may be one of the effective ways to improve the biodegradability of butyl xanthate.
摘要：
A neutralization hydrolysis route has been used to synthesize titanium oxide nanoparticles. Transmission electron microscopy(TEM) and X-ray diffraction(XRD) characteri- zation results showed the TiO2 nanoparticles were single anatase phases when calcined at 600°C-800°C for 2h. The particle diameter ranged from 15 to 30nm. The pH value was key factor for precursor composition. When pH value 2-4, the H2TiO3 precursor with low agglomeration was obtained. As-prepared anatase TiO2 nanoparticles, during photodegradation of methylic orange under UV-light irradiation(λ=254nm), exhibited excellent activity, more than 95.5% methylic orange was degraded in 1h.

摘要：
The idea of smart growth has been accepted by many farseeing cities around the world. Their goals are to concentrate growth in the center of a city to avoid urban sprawl. Against this background, shared parking which needs less space but provides more parking spaces is welcome in urban area. However, it has been still a challenge for traffic engineers and metropolitan governors to make parking garages and lots in large-scale area, especially in the central business distribution, shared as an integrated one. This paper tries to adopt traffic organization to solve the problem of shared parking. First, it introduces space syntax which is a paradigm of city and modifies its behavioral hypotheses for motor vehicles. Then, it improves the traffic system by making use of space syntax in traffic organization combining with parking guidance and information system (PGIS). Finally, it presents the application of this method in Yanghuyuan micro center business district (MCBD), which is located in Changsha, China.

摘要：
Constructing metro tunnel in shallow stratum destroys surrounding stratum structure, causing corresponding deformation and settlement of stratum. So it's very important to accurately predict stratum deformation and settlement for metro tunneling. In this paper, the features of FLAC3a and built-in material constitutive model are firstly analyzed, then compared with other calculating procedures, besides it is used to predict stratum deformation and settlement caused by the Shenzhen metro tunneling. It can be seen from the numerical results of the calculation obtained from FLAC3D that stratum deformation and settlement agree well with that of in-situ measurement, and can reflect the typical characteristics and change laws of stratum deformation and settlement caused by metro tunneling, which indicates that using FLAC3D to analyze stratum deformation and settlement caused by metro tunneling is feasible.
摘要：
The purpose of this paper is to construct the option pricing model of land- use right based on the real option theory. Method of real option model was employed. The results indicate that the land- use right is interpreted as an American call option, the underlying asset is regarded as housing price, the price of land-use right includes two parts, the discounted value of land development income and development of premium (real option value). It is concluded that the land development decision-making faces growing uncertainties, which makes the discounted cash flow method more and more unsuitable for pricing of land-use right, because the traditional method neglects the uncertainty and flexibility, which underestimates the value of land-use right, and affects the psychological price of real estate developers, while in the “highest bidder” policy, underestimating price often leads to failure of the land bidding; however, the real option theory applied to the pricing of land use right can effectively determine the maximum price of land use right and overcome the deficiencies of traditional pricing methods, which can improve the offer capacity, and prevent over-bidding.

摘要：
Most of graph-based methods for semi-supervised learning are transductive, giving predictions for only the unlabeled data in the training set, and not for an arbitrary test point. SLC(Semi-supervised Local Linear Coordinate), which is based on LLC(Local Linear Coordinate) is present here as an inductive method. The mixture of factor analyzers is used to model the raw data set, and the label smoothness over the graph is enforced by local approximation. At last, smooth nonlinear projection is achieved by local affine transformation. Experiment shows the superiority of our proposed method in comparison to others.

摘要：
I2S (Inter-IC Sound Bus) is one of the general audio buses applied in various industrial or embedded systems. It only processes the audio data, while other signals like various codes and control signals are transmitted individually. This paper presents an approach how to construct an embedded audio system using the I2S bus to connect relevant supporting code chip and decode chip. This system can reduce the consumption of system resources drastically, therefore fluent WAV broadcast can be guaranteed. Moreover, the familiar media files, such as MPEG1, MPEG2, MP3, MPEG4 can be played through adding its decoder. The ARM chipset of the LPC2300 series is applied in this system, therefore, system's reliability can be improved. This method can be wiedly used in vehicle- borne, ship-borne embedded flash players and portable media players.

Characteristics of Luminescent;Microstructure;Porous Silicon (PS);Sonic Vacating-Method
摘要：
The special physicochemical environment caused by sonic-vacating provides an important outlet for the preparation of highly efficient luminescent porous silicon films. Experimental results show that sonic chemical treatment is an effective technology for the improvement of the microstructure of porous silicon, and the luminescent efficiency and stability thereof. Luminescent porous silicon films, prepared by ultrasonic enhanced anode electrochemical etching, display better qualities than the samples prepared by conventional methods widely used at present. This ultrasonic chemical effect roots in sonic vacating, i.e. the generation, formation and rapid collapse of bubbles in the etching solution. In the process of the porous silicon being etched, the escape rate and caving-in of hydrogen bubbles in the pores is increased as a result of the work of the ultrasonic waves, which is helpful to the vertical etching of the pores.

摘要：
On the basis of Bieyancao Tunnel project, which is one of the eight level I risk tunnels in Yichang - Wanzhou railway line, the safety risks for tunneling in fault fracture zone are analyzed. The safety risks include mutations of engineering geology and hydrogeology, surrounding rock instability, sudden water inflow, structural damage of tunnel lining, exhaustion of groud water in tunnel top. Based on that, an idea is presented that the key to safety risk control of Bieyancao Tunnel is precise geological forecast system and reliable grouting reinforced structure system. By means of advance detection, a detail forecast is made for the geological conditions of F1 fault fracture zone and its influence zone. The reasonable thickness of grouting reinforced region is determined in engineering analogy method, and water plugging reliability of grouting reinforced region is checked by theoretical calculation. The tunnel construction shows that, practical geological conditions are very close to forecast results, the water plugging results of grouting reinforced structure system is very close to theoretical calculation, and the stable grouting reinforced structure system guarantees a safe tunnel project. The safety risk control system used in Bieyancao Tunnel has a very good effect, and it can be used for reference in similar projects.
