Some designers are not familiar with the design codes of steel construction, and lack of professional training of steel structure; some products are designed by manufacturers and design institute signatures.
Otherwise, because of long-term exposure to outdoor for steel sheet material and other components, the atmospheric and water stability is poor, premature corrosion and lower strength may occur, and the maintenance period will be shorten, leaking phenomenon will also occur. Ⅵ Conclusion (1) On the basis of the characteristics of granary railway canopy, although there is no design codes for arched roof structure, combined with the more complex factors, the design has regulations to follow in accordance with the relevant codes.

The most prominent feature of collapsible loess is the additional settlement is rapid and larger by water and self weight of soil or additional stress.

The development of the non-agricultural industries in bring good economic benefits, in situ absorption of rural labor employment at the same time, will inevitably leads to air pollution, water pollution, soil pollution and noise pollution and so on a series of environmental problems and ecological destruction.
One is the standard land circulation program, land circulation must sign a standard contract, a registration system, the village committee by the record, rural land contracting contract management department registration; Two is to strengthen the service, building rural land contracted management institutions, and seeking a proper settlement of staffing, working funds, timely to provide farmers with standard contract forms the land circulation; Three is to strengthen the intermediary service function, provide for land circulation land policy, transfer, information transmission, the legal consultation and land price evaluation services, and other projects. 4 it is to speeds up the agricultural informatization construction, and promote the agricultural information got to the village door engineering, establishing agricultural products price survey and release system, professional and technical personnel connection base system, natural disasters and major animal and plant diseases and insect

Experiment Materials and Equipments The main experimental materials include sub-micron titanium dioxide particles, deionized water, cationic dispersants and anionic dispersants.
Fig.8 Black/White swap The following graphic can be achieved with selecting the appropriate length scale processing map by professional image analysis software, according to box counting method, fractal dimension D can be calculated.

The samples were polished in a mechanical, using a suspension of composed polishing for: 100 mL OP-S, 30 mL deionized water, 10 mL oxygen peroxide (30 vol.), 0,4 mL HF (48 %), 0,2 mL HNO3 (65 %) impregnated in cloths of nylon type (DP-PLUS).
The acquisitions of the images were accomplished through a digital camera (PIXERA PROFESSIONAL) and in the quantification analysis the program used was Measured Cybernetic Image for Plus 4.0 / Materials-Pro Analyzer 3.1, in agreement with the norm ASTM E 1382-99.

Wet":in addition to hot summer and cold winter,another factor causing our country region of hot summer and cold winter climate condition is not livable is high humidity in summer and winter.Due to water network is densely,numerous lakes in the middle and lower reaches Yangtze,air humidity is maintained all the year round in 80% or so.Due to high temperature and humidity in summer,it’s hard for human sweat to volatilize and discharge,causing more sultry sense.Wet vapor from the human body absorb heat in winter,together with the relatively a litter seasonal sunlight,making human feel more cold and damp.
The simulation using the Fluent software,Fluent software is a kind of CFD commercial software, used to simulate complex flow from incompressibility to a highly compressibility.Due to the adoption of several solution methods and multi-grid acceleration convergence,Fluent can obtain the optimal convergence speed and precision.Fluent Air-pak is geared to engineers,architects and designers professional artificial environment system analysis software, especially HVAC domain,can simulate the internal air flow of object,heat transfer and pollution physical phenomenon precisely,can simulate the ventilation system air flow,air quality,heat transfer,pollution,comfort degree and other problems accurately,and provide comfort,PMV,PPD measure of indoor air quality ( IAQ ) technical indicators in accordance with ISO 7730 standards.
