Due to the weak construction technical standard and the lack of appropriate building materials, the small town was short of overall design.
Thus residential building system cannot be systematized, residential complete technology level is completely at a disadvantage position and Often becomes the "colony” for city to transfer lag materials and technology.

However, owing both to the excellent properties of the original materials, in particular, Japanese Hinoki tree, and to the good conditions at the site, approximately 80% of the timbers materials are surviving from the original construction.
In order to solve this problem, the light materials of bark or bronze plate were usually used after the medieval period as the roofing materials for new construction of pagodas.
This alteration of roofing materials also might contribute to improvement of seismic performance, but might not contributed to wind performance.
The roofing materials of this pagoda are copper plates, indicating that this timber pagoda is lighter than the pagoda utilizing tiles with a mud layer for roofing.

However, it should be noted that the materials used for this investigation contain small amount of carbon (12~16ppm).
Experimental procedure Table 1 is the list of materials used in this investigation.
The sample Fe-17%Cr was used as referential materials to investigate the effect of solute carbon.

When collecting dust in this atmosphere, the infiltration of liquid matter including water or oil will deteriorate the filter materials and the chemical composition will attack all the materials with which it come into contact, reducing the filter life [[] Information on ttp://www.seas.columbia.edu/earth/wtert/sofos/nawtec/1990-National-Waste-Processing-Conference/1990-National-Waste-Processing-Conference-18.pdf ].

They were impregnated into padding liquor containing fluoropolymer and acrylic resin[[] H.Shao, J.Y.Sun, W.D.Meng et al: Textile research Journal.
After about an hours later, the filter media also can provide an hydrophobicity which can prevent the moist from infiltration of dust cake, causing a high pressure resistance to air laden with fine dust[[] B.H.Park, M.Lee, S.B.Kim et al: Applied surface Science.

Influence of ageing on yield stress anisotropy of extruded 7075 aluminum alloy bar at ambient temperature Zhimin ZHANG1, a, Yongbiao YANG, b, Keren Xu 2, c (1 College of Materials Science and Engineering, North University of China，Shanxi Province Taiyuan 030051, China) ( 2 Capital Aerospace mechanical company )2 azhangzhimin@nuc.edu.cn, byangyongbiao@yahoo.cn. cforge54@sina.com Keywords: 7075 aluminum alloy; elongated grain; solution; aged; texture Abstract: Uniaxial tensile tests of extruded 7075 aluminum alloy bar were carried out on the universal test machine at strain rate of 0.001 s-1.
Introduction The 7xxx series aluminum alloys have been widely used as structural materials due to their attractive comprehensive properties, such as low density, high strength, ductility, toughness and resistance to fatigue [1-3].
This material was supplied as hot-extruded bar of φ190mm, which was in H112 condition.

Furthermore, Lippmann and Berge et al. pointed out that the shape of liquid materials on the solid surface was changed when the voltage was applied to the liquid[5,6], and this phenomenon is called the electrowetting.
The cell tissue fluid can be considered as the liquid materials, and could the cell tissue fluid show the electrowetting under electric potential?
The liquid materials in the solid surface are kept the balance by the three-phase interfacial tensions in the natural state, and it is formed an initial contact angle at the three-phase contact line.

Introduction Concrete materials are widely used in building engineering, it is important to strengthen supervision and guarantee the quality of concrete material when the existing buildings need extension and strengthening.
In addition, for comparing the results of nondestructive methods for existing building and common destructive methods, they have five characters: (1) nondestructive methods can be used directly and real reflect the quality and strength of structural concrete materials, (2) the newly built engineering and existing building all can be tested using these methods, (3) these methods have many advantages such as easy operation, small destroy, (4) no limits of size and shape, they can repeat test for many times, (5) the detection accuracy of these methods should be improved.
The design strength of concrete material (f0)was given firstly under normal case, the lower and upper confidence limits will be obtained using the methods of reference [1], and namely the evaluation strength fcu.e, the upper confidence limit fU and the lower confidence limit fL, and the strength of concrete material is always more than 0, Then the number axis can be divided into four parts
