The toxic metals originate from the mined out sulphide ore veins hosted in Miocene age andesite rocks. 1-3 pH leachate is being produced around the waste rock heaps due to the complex chemical and biological oxidation of the pyrite containing material in contact with the rainwater and runoff.
Given the topography (steep slopes), hydrogeology (high infiltration rate) and geology of the area and the site-specific processes due to the mineralogical composition of the ore, mine waste material and country rock (leaching, bioleaching, partition) the runoff water is the main pollution pathway in the conceptual risk model, and to a lesser extent the pore water.
Leaching of metals from pollution sources and the characteristic parameters of the process were given based on a complex (physical-chemical-biological) leaching test using the mine waste material from the area.
The key parameters of the risk were determined: the rate of acidification and metal mobilisation and the metal concentration of the emitted leachate.

Use the Conception of Universal Design to Instruct Housing Construction Hong CAO College of Civil Engineer and Architecture, Guangxi University，Nanning, China E-mail:redfreebird@sohu.com Key words: universal design, housing construction, barrier-free, universal house Abstract.
Units of universal houses can be adjusted or modified without re-building or changing the structure and citizens can, based on utilization requirements, finish some simple non-structure adaptable reformations by themselves, such as conducting reformations of “adapting to the aged” by stage on the interior space, structure, facilities and equipments considering the physiological need that the aged are changing all the time, including changing the interior discrepancy in elevation into slopes, laying anti-skid materials on the ground, enlarging the width of door frameworks, lowering the height of washing counters, removing the wall cabinets so that the basin in the kitchen and bathroom can accommodate knees, arranging handrails in where it is required on the wall and setting up the emergency alarm system, etc.
Therefore, the conception of promoting universal houses is put forward: the State or enterprises build some material houses, track and investigate residents’ utilization status, compare the utilization effect, current issues and social benefits with those of common houses, test the feasibility and superiority of universal houses and further promote and popularize them.

This reduction process is usually divided into the following 3 stages: Restore the symbols to the association of the sign and signified, that means the specific form of symbols, just like forms, colors, materials, technology and so on.
Some of these symbols exist in material form, while some in spirit form.
Science and technology provide technique support for automotive design, as new materials, new technology application on the vehicle model have a huge impact on it.
Since the 80s of the 20th century, fast development of materials science and processing technology, electronic technology, internet applications, computer-aided design applications, as well as aesthetic and artistic knowledge and taste of the advances in automotive design have been more and more reflected.

Lead acetate, zirconium propoxide, titanium isopropoxide, lanthanum nitrate and PVP with the molecular weight of 3.6x10 5 were chosen as starting materials.
The nearly full densification of the PLZT films annealed at 700°C can be attributed to the occurrence of liquid-phase sintering since 35% excess of Pb was added in our material system.

Analysis of Coupled Electro-thermal-mechanical of Micro Gas Pressure Sensor Based on Micro-hotplate Technology Rencheng Jin 1, a, Wujin Zhang 1,b, Zhenan Tang2, Jiaqi Wang2 and Mingliang Shao1 1 Key Laboratory of Micro-system and Micro-fabricating Technology, Dalian University of Technology, Dalian, China 2 Department of Electronic Engineering, Dalian University of Technology, Dalian, China a rcjin@dlut.edu.cn, b zhangwujin82@126.com Keywords: Thermal conduction vacuum gauge, Micro-hotplate, Coupled analysis Abstract.
For the MHP-based micro gas pressure sensor, the MHP is usually constructed by multilayer films in order to enhance strength and reduce the total intrinsic stress, and because different materials have different thermal expansion coefficients, when the sensor is working at higher temperature, the MHP will produce thermal deformation, which will change the gas gap distance between the MHP and the substrate and induce gaseous thermal conduction change.
The former is induced by the temperature change after films deposit, and the latter is formed during the process of the films growth, whose magnitude is relation with material and process.

Therefore, the choice of a substrate material could be limited [13-15].
For this sample, plasma damage on the substrate was negligible, because silicon is as hard a material as the substrate.

the coordinate z (assumed to be positive within the material).
Another way to explain this phenomenon is by way of considering the misfit between plastically deformed material and the remaining body: the near-surface layers of material that have been plastically stretched find themselves too long for the substrate, and must be compressed to fit.
Strain measurement by synchrotron X-ray diffraction Energy-dispersive white beam diffraction is a highly efficient technique for the experimental evaluation of average lattice parameters within polycrystalline materials.
