Introduction Slope stability has long been an important research subject for geotechnical engineering, in which departments of water conservancy, transportation, mining, national defense and so on involve largely.
At present, a number of large universal and professional softwares have been developed based on FEM, such as ANSYS, ADINA, MARC, ATRAN, etc.

Therefore, detection of soil caves with water or clay in the soil layer or the empty caves within the bedrock is with low efficiency [10].
For instance, carbonaceous limestone shows low resistivity, which is close to the resistivity of water-saturated strata materials, and it’s hard to extract water-bearing information when the low resistivity layers are interbedded with high-resistivity layers[2,9].
The borehole ZKS551 located at the right survey line chainage K253+257m reveal the cave with an obvious signs of water erosion, and filled with breccia (30%), silty clay.
However, when the carbonaceous limestone area is developed with karst caves filled with air or water/clay, the resistivity of the caves is quite different from that of the surrounding bedrock.

Relevant data sources are mainly in Slovakia: Slovak Hydrometeorological Institute, which provides meteorological and hydrological forecasts and warnings, weather analysis, weather history, emissions, air quality, Slovak Water Management Enterprise, sp, which indicates the flow conditions and water resources.
Moreover, due to the complexity of the functions are GIS applications to modeling flood situation almost ideal for a wide range of flood protection at the professional and scientific work analyzing the myriad of landscape indicators for floods.
The first phase of flood modeling using raster calculator option creates a new layer in the format specified GRID reflecting elevation of water level of the river.
This procedure is defined in the following steps the increasing water level of water flow, but that still does not reflect the course of the river bed and thus determines only the area of potential flooding hazards due to a lower altitude values than the given height level.
This form of the model shows the flood risk areas around the river in question set specific elevation of the water surface.

It suffers gas pressure within the specimen and suffers water pressure, transformed by the gas pressure, outside the specimen.
Respectively imposing different size of water and gas pressures, the specimen produces the corresponding radial stress σr.
Measured by the standard compaction test, the maximum dry density of the loess is 1.60 g/cm3, the optimal water content is 19.7%.
By water film-transfer method, the water content of compacted loess sample is controlled at 19.7%, and conserves in the conservation tank for 3 days.

In China, there are two professional journals publishing papers on wetlands, Wetland Science and Wetland Science & Management.
Tab.2 Major English journals publishing wetland science papers written by Chinese researchers (1957–2009) Order Journal Number of publications Percentage (%) Impact factor(2008) 1 Wetlands 248 7.74% 1.117 2 Ecological Engineering 81 2.53% 1.836 3 Journal of Environmental Quality 60 1.87% 2.145 4 Hydrobiologia 50 1.56% 1.449 5 Water Research 41 1.28% 3.587 6 Aquatic Botany 37 1.15% 1.129 The author distribution of the wetlands scientific literature During 7,788 Chinese and English literature published by Chinese researchers, there was totally 6,121 first authors published paper, accounted for 78.6% of the total number of all the literature, this close to Lotka's inverse-square law, author who published one paper account for 60% of total calculated value of all author [8], it indicate that the author distribution of wetland scientific literature normal exist discrete description.

The emergency information system may involve following departments: public security, fire control, civil air defense, environmental protection, first aid, police, power, drug administration, seismological bureau, oceanic administration, meteorology, chemical administration, tap water companies, the gas company, civil affairs bureau, port office, drought and flood control headquarters, the railway, airports, Red Cross, petroleum and other government departments, make these departments’ various information data unified integration to realize linkage inquiry[2][3].
A) The establishment of database The databases required in emergency plans are: expert members library, leadership decision library, organization library, resource library, geographic information library, and other related information database. 1) Expert members library Expert members library is formed with professional who are needed for emergency, providing decision-making information for emergency managements, technical information and attending the emergency work.
The corresponding information should be contained in itself, such as the need data information of geographical location, the height and winding of mountain, the depth and wide of water, the grade and range of bridge and railway, lane number and journey.

Coal seam cavity technology.The professional cavity bit of CBM produced by the institute of exploration techniques of the Ministry of Land and Exploration is adopted.
The drilling is in under-balance situation, which will be useful to prevent water blocking damage brought by high differential pressure fluid.
As a result, many problems in Binchang mining area, such as water-shortage in construction, collapsing and breaking of coal-bearing strata, and mud loss in fritted rocks section, can be solved.

The U.S. definition of energy-saving and environmental protection industry between OEDC environmental protection industry and environmental protection industry, they divided it into three categories: energy -saving and environmental protection services, environmental protection equipment, and environmental resources.[2]This paper focuses on energy-saving and environmental protection equipment, which mainly includes: oil-water treatment equipment, instruments and information systems, air pollution control equipment, waste management equipment, cleaner production and pollution prevention technologies and equipment.
For an industrial enterprise, the establishment and implementation of product image is a gradual process, whether start from the business inside, or in collaboration with a professional design company, the first selection of a suitable product design is the safest and effective way to ensure the accuracy and adaptability of the latter system.[6]The selection should satisfy a number of conditions: the product is typical, to reflect the typical characteristics ;‚ easy to grasp the characteristics and features;ƒ mass production and smaller craft restrictions;„structural engineers and industrial designers should participate the selection of product meanwhile.

Tourmaline is endowed with spontaneous polarization which enables it to generate an electric field on the surface, which facilitate the photoelectrocatalytic effect of sub-micro/nano-grade ZnO and may be helpful to improve ZnO's electromagnetic properties according to the built-in field theory[4] because of the two reasons below: (1)Tourmaline facilitates the capture of holes Tourmaline's surface electric field may drive water molecules to be ionized, which results in reduced water molecule groups, enriches the concentration of OH-, facilitate capturing holes and reduces hole's constraint on electrons on the surface, thus enhances its conductivity.
