采用高能球磨工艺制备了Al2O3弥散强化316L不锈钢喷涂粉末,并进行高速火焰喷涂(HVOF)试验。研究了弥散强化粉末及其喷涂层的微观组织结构和硬度。采用销-盘磨损试验机测试了涂层的耐磨性能。结果表明,球磨加工后,Al2O3颗粒尺寸大多小于1μm,由微米级、亚微米级及纳米级粒子组成并均匀分布在316L不锈钢基体粉末中。随着球磨时间的增加,粉末的显微硬度提高。喷涂后球磨粉末的微观组织结构基本不变,喷涂层的硬度比对应球磨粉末硬度低,其耐磨性明显优于单纯不锈钢粉末涂层。

出于可重复性考虑,车辆空气动力学和气动声学的研发工作主要在风洞中稳态流动条件下进行,然而在真实路况下车辆经受着非稳态湍流,这是由比如侧风阵风、路边障碍物与稳定侧风的组合影响或前方行驶的车辆所引起的.为了能够以可重复再现的方式来模拟该路面场景,开发了一套主动湍流发生器系统FKFS swing?,并运用于斯图加特大学的全尺寸气动声学风洞中,风洞由FKFS运营.该系统由垂直跨越风洞喷口的8个翼型组成,能够以高达10 Hz的频率动态改变流动角度.先前的研究表明,开口射流对主动偏转的动态响应改变了由位置和频率变化所产生的流动角度.一种用于量化该特性的方法被提出并运用于斯特劳哈尔数高达0.45的情况.本研究中,该方法被用于分析更高斯特劳哈尔数至1.2情况下的动态响应,这与非稳态气动声学相关.结果表明,在更高的斯特劳哈尔数下射流特性对流动角度的影响减小.

Traffic simulation can help to evaluate the impact of different mobility behaviors on the traffic flow from safety, efficiency, and environmental views. The objective of this paper is to extend the SUMO (Simulation of Urban Mobility) road traffic simulator to model and evaluate the impact of motorcycles mobility on vehicular traffic. First, we go through diverse mobility aspects and models for motorcycles in SUMO. Later, we opt for the most suitable mobility models of motorcycles. Finally, the impact of motorcycle mobility on different kinds of vehicles is investigated in terms of environment, fuel consumption, velocity and travel time. The result of modeling and evaluation shows that based on the mobility model of the motorcycle, vehicular traffic flow can be enhanced or deteriorated.

Could wastewater analysis be a useful tool for China?——A review

Journal of Environmental Sciences 2015年第1期27卷 70-79页

Analysing wastewater samples is an innovative approach that overcomes many limitations of traditional surveys to identify and measure a range of chemicals that were consumed by or exposed to people living in a sewer catchment area. First conceptualised in 2001, much progress has been made to make wastewater analysis（WWA） a reliable and robust tool for measuring chemical consumption and/or exposure. At the moment, the most popular application of WWA, sometimes referred as sewage epidemiology, is to monitor the consumption of illicit drugs in communities around the globe, including China. The approach has been largely adopted by law enforcement agencies as a device to monitor the temporal and geographical patterns of drug consumption. In the future, the methodology can be extended to other chemicals including biomarkers of population health（e.g. environmental or oxidative stress biomarkers, lifestyle indicators or medications that are taken by different demographic groups） and pollutants that people are exposed to（e.g. polycyclic aromatic hydrocarbons,perfluorinated chemicals, and toxic pesticides）. The extension of WWA to a huge range of chemicals may give rise to a field called sewage chemical-information mining（SCIM） with unexplored potentials. China has many densely populated cities with thousands of sewage treatment plants which are favourable for applying WWA/SCIM in order to help relevant authorities gather information about illicit drug consumption and population health status. However, there are some prerequisites and uncertainties of the methodology that should be addressed for SCIM to reach its full potential in China.

Thioredoxins Play a Crucial Role in Dynamic Acclimation of Photosynthesis in Fluctuating Light

Sunlight represents the energy source for photosynthesis and plant growth. When growing in the field, plant photosynthesis has to manage strong fluctuations in light intensities. Regulation based on the thio- redoxin （Trx） system is believed to ensure light-responsive control of photosynthetic reactions in the chlo- roplast. However, direct evidence for a role of this system in regulating dynamic acclimation of photosyn- thesis in fluctuating conditions is largely lacking. In this report we show that the ferredoxin-dependent Trxs ml and m2 as well as the NADPH-dependent NTRC are both indispensable for photosynthetic acclimation in fluctuating light intensities. Arabidopsis mutants with combined deficiency in Trxs ml and m2 show wild- type growth and photosynthesis under constant light condition, while photosynthetic parameters are strongly modified in rapidly alternating high and low light. Two independent trxmlm2 mutants show lower photosynthetic efficiency in high light, but surprisingly significantly higher photosynthetic efficiency in low light. Our data suggest that a main target of Trx ml and m2 is the NADP-malate dehydrogenase involved in export of excess reductive power from the chloroplast. The decreased photosynthetic efficiency in the high-light peaks may thus be explained by a reduced capacity of the trxm lm2 mutants in the rapid light acti-vation of this enzyme. In the ntrc mutant, dynamic responses of non-photochemical quenching of excita- tion energy and plastoquinone reduction state both were strongly attenuated in fluctuating light intensities, leading to a massive decrease in PSII quantum efficiency and a specific decrease in plant growth under these conditions. This is likely due to the decreased ability of the ntrc mutant to control the stromal NADP（H） redox poise. Taken together, our results indicate that NTRC is indispensable in ensuring the full range of dynamic responses of photosynthesis to optimize photosynthesis and maintain growth in fluc

Online Process Control of Alkaline Texturing Baths: Determination of the Chemical Concentrations

引用

American Journal of Analytical Chemistry 2014年第3期5卷 205-210页

作者： Martin Zimmer Katrin Krieg jochen Rentsch Department PV Production Technology and Quality Assurance Fraunhofer Institute for Solar Energy Systems Freiburg Germany

Almost every monocrystalline silicon solar cell design includes a wet chemical process step for the alkaline texturing of the wafer surface in order to reduce the reflection of the front side. The alkaline texturing solution contains hydroxide, an organic additive usually 2-propanol and as a reaction product silicate. The hydroxide is consumed due to the reaction whereas 2-propanol evaporates during the process. Therefore, the correct replenishment for both components is required in order to achieve constant processing conditions. This may be simplified by using analytical methods for controlling the main components of the alkaline bath. This study gives an overview for a successful analytical method of the main components of an alkaline texturing bath by titration, HPLC, surface tension and NIR spectrometry.

Literature Survey on Recent Progress in Inter-Vehicle Communication Simulations

Journal of Transportation Technologies 2015年第3期5卷 159-168页

作者： Markus Hager jochen Seitz Thomas Waas Fachgebiet Kommunikationsnetze Technische Universit&auml t Ilmenau Ilmenau Germany Labor Computernetzwerke Ostbayrische Technische Hochschule Regensburg Regensburg Germany

The vehicular ad hoc network (VANET) technology based on the approved IEEE 802.11p standard and the appendant inter-vehicle communication (IVC) has the potential to dramatically change the way transportation systems work. The fundamental idea is to change the individual behavior of each vehicle by exchanging information among traffic participants to realize a cooperative and more efficient transportation system. Certainly, the evaluation of such systems is a comprehensive and challenging task in a real world test bed, therefore, simulation frameworks are a key tool to analyze IVC. Several models are needed to emulate the real behavior of a VANET in all aspects as much realistically as necessary. The intention of this survey is to provide a comprehensive overview of publications concerning IVC simulations of the year 2013 and to see how IVC simulation has changed since 2009. Based on this analysis, we will answer the following questions: What simulation techniques are applied to IVC? Which aspects of IVS have been evaluated? What has changed within five years of IVC simulations? We also take a closer look at commonly used software tools and discuss their functionality and drawbacks. Finally, we present open questions concerning IVC simulations.
