Abstract: Since 2013, lots of places in China have suffered serious fogs and hazes, therefore a number of measures have been taken to alleviate the problem, especially in some big cities such as Beijing, Tianjin, and Shijiazhuang. Some of the measures are targeted at automobile industry. This paper gave some suggestions about fog and haze prevention after analyzing the major causes of haze weather; meanwhile, it explained the positive influence on automobile industry. As far as automobile industry is concerned, it is necessary to issue related standards, laws and regulations as soon as possible. On the other hand, the development of new energy vehicles will help alleviate air pollution, and our purpose to avoid haze weather can be achieved.

Abstract: Exhaust of propellant vapor in a confined space in case of forced ventilation was simulated by use of software Fluent. Calculated several situations, such as different vent position, vent number, and ventilation speed. The result shows that the lower of vent position, the more obvious the exhaust effect, and the more the vent number, the better the exhaust effect, and the higher the ventilation speed, the rapider the decrease of concentration of propellant vapor.

Abstract: Despite the fact that active brazing is a suitable and well-established method to join ceramics to each other and to metals, issues concerning possible influences on the wetting properties of the used filler alloys are not yet entirely clarified. It is well known that process parameters such as the temperature, the surface roughness of the ceramic, and the atmosphere during wetting influence the wetting angle and the spreading kinetics of the molten filler metal. However, a quantitative description of these influences is still missing.This study closely investigates the isolated effects of the temperature, the surface roughness of the ceramic, as well as the atmosphere on the wetting of Ag-Cu-Ti and Cu-Sn-Ti on silicon carbide. In order to evaluate the effects of the considered factors as well as their interdependencies, a multivariate statistical approach is employed and a linear regression model for both, the contact angle and the spreading area, will be derived. Besides quantitative measurements of the contact angle on solidified sessile drops, microstructural and chemical aspects will be discussed and connected to the results of the wetting experiments as well. By these means, valuable information can be obtained, which lead to a profound understanding concerning changes of the wetting behavior. Furthermore, the study allows a comparison of measurements carried out using varying experimental conditions.

Abstract: Firefighter uniform made of various flame retardant materials is put as the object. Analyzing the thermal protective performance of different composite structures covering outer fabrics, lagging materials and comfortable layer materials, discuss the best combination of supporting structures. Adoption flash fire simulation, verify the integrated prevention ability of firefighter uniform. The matching of different levels has a significant impact on the thermal protective performance, first the outer layer, then comfortable layer and thermal protective coating. Although inherent fire resistant fiber for the main material of the outer fabric has better durability and thermal protective performance, the fire might experience obvious contraction which leads to embrittlements. For insulation flocculus, the ratio of aramid fiber 1313 and aramid fiber 1414 at 9:1 has excellent thermal insulation. For comfortable layer, inherent fire resistant fiber has no notable effect on the clothing’s overall thermal protection performance; the polysulfonamide fiber is a relative better choice.

Abstract: Free-standing museum cultural relics are easy to fall off exhibition booth and get damaged under earthquakes. To find an effective method to mitigate damage of cultural relics due to fall off, influences of soft pad under relic was studied by ANSYS/LS-DYNA program. A bronze relic supported by a soft pad was selected for analysis. Based on material properties of both the relic and the pad, finite element model of the relic was built. By simulation, Von mises stress distributions, acceleration response curves as well as kinetic energy curves of the relic were obtained; effects of the soft pad to mitigate damage of the relic were discussed. Results show that collision between the falling museum cultural relic and ground can be mitigated by soft pad due to its buffer as well as energy absorption effects. It is suggested to use soft pad under relic to provide protection. Besides, by ANSYS/LS-DYNA program, falling off process of free-standing museum cultural relics can be effectively simulated.

Abstract: Cyberculture or computer culture is the culture that has emerged, or is emerging, from the use of computer networks for communication, entertainment, and business. It is also the study of various social phenomena associated with the Internet and other new forms of the network communication, such as online communities, online multi-player gaming, wearable computing, social gaming, social media, mobile apps, augmented reality, and texting, and includes issues related to identity, privacy, and network formation. With the era of cyberculture, ideological issues are prominent increasingly at all levels of society in cyberculture.

Abstract: From physiology perspective, always disturb people to rest, the sound that learn and works, namely do not need to voice, all are considered noise. When noise to the people and the surrounding environment adverse effects, the formation of the noise pollution. This paper analyzes the harms and the effects on people, and puts forward prevention and control measures.

Abstract: Traditional Chinese culture has such a long and splendid history that its influence on interior design shall never be neglected due to its inexhausitible vitality. As flourishing traditional Chinese culture is the result of interaction among Confucianism, Taoism and Buddism, these three traditional Chinese Schoolsl exert tremendous influence on shaping neoclassical interior design.

Abstract: The development of modern information technology to accelerate the rapid development of high technology, the rapid development of high technology and promote the differentiation and integration of university disciplines. By describing the main contents of modern information technology, and analyzes the impact of modern information technology on Teaching Reform of higher education and university teachers from the use of multimedia technology to improve the level and increase the ability of teachers to use modern distance education university and college teachers to improve the teaching of measures to address three aspects of information literacy universities.

Abstract: As nanotechnologies become more widely used, titania nanoparticles are being released to the subsurface environment via wastewater sludge applications. Titania nanoparticles are not only toxic to organisms in the environment, but recent studies revealed that they may also serve as carriers of hydrophobic organic contaminants and affect their fate and distribution in the subsurface environment. The mobility of titania nanoparticles varies depending on nanoparticle morphology characteristics, pH and the ionic strength of solutions, flow velocity, nanoparticle concentration, and the presence of surfactant or natural organic matter. Analogous to findings for natural and engineered carbonaceous nanoparticles, titania nanoparticles may enhance the transport of hydrophobic organic contaminants in porous media. However, to prove this hypothesis, further research is necessary. Thus experiments examining the impacts of titania nanoparticle on the hydrophobic organic matter transport in porous media were designed, which consist of three different sets of column experiments. These experimental sets will investigate the effects of the presence of titania nanoparticles, the size of nanoparticles and the organic carbon content in soil, respectively. Due to the estimation of the potential for the titania nanoparticles to facilitate organic contaminant transport, the experiment results are expected as: (a) the presence of titania nanoparticles will enhance the organic contaminant transport in porous media; (b) smaller nanoparticles will adsorb more organic contaminants and enhance their transport as the result of the increasing specific surface area; (c) soil containing higher organic matter content will compete for the adsorption of organic contaminants and retard their facilitated transport by titania nanoparticles.
