For example, high water impurities is one of the risk sources from material layer, it causes machine to be poor running and causes unusual work.
While the risk sources of the resource are mainly raw materials, natural attributes, such as flammable and explosive hydrogen gas, dissolution of local water and etc.
Before the accident the 2nd unit loaded 200MW with normal operating parameters. 15:06 PM the 2nd unit issued a warning signal, then the turbine driver, monitor, checked the value of stator cooling water pumps, and to determine the signal was an error. 15:08 PM, the BTG plate of the 2nd boiler issued MFT (master fuel removal) action signals as a protection malfunction.

The following should be considered when corrosion-resistant alloy is selected in accordance with ISO 15156-1[1,2,3]: 1) Temperature during service; 2) Partial pressure of hydrogen sulfide and carbon dioxide in gas phase;3) Existence of elemental sulfur;4) Concentration of Cl- or other halide;5) pH value of water phase.
Sometimes formation water may have a high chloride content, and some wells use high-concentration salt water or natural brine for killing a well.

Along with serious blowout and oil spill accident in Gulf of Mexico and Australian waters few years ago, research area related to well integrity has become a global focus.
In cementing engineering, the effective sealing of oil, gas, and water layer is the most important goal.
An important premise of water or gas channeling and sustained casing pressure caused by wellbore integrity failure is: there is pressure difference exists between the annulus and the formation or interlayer.
In fact the cementing quality evaluation is a multidisciplinary technology, combine the wide variety of professional knowledge, we could find out the real reason of cementing quality problems, and carrying out new detection and evaluation method of cementing quality.

These methods involve professional judgment, hard to explain to public and not likely to be accepted in today’s environment.
In the table, it shows that the new selected landfill must buffering 1000m from residential, 100mm from water bodies, 1000m from groundwater sources, and 25km from transfer station.
Standard criteria for new landfill site selection Malaysia specification 1 Residential (m) 1000 2 Water bodies (m) 100 3 Groundwater line (m) 1000 4 Distance from transfer station (km) 25 5 Protected forest (m) 3000 6 Airport location (m) 3000 7 Road line (m) 500 8 Slope (%) 10 9 Soil permeability (cm/sec) <10-6 10 Fault line (m) 100 Methodology Analytical Hierarchical Process (AHP) AHP is one of the methods in Multiple Criteria Decision Analysis (MCDA).
Table 3: Overall priority rating The results achieved shows that the landfill selected must be in safe buffering zone from river because the river could easily contaminated by the landfill waste such as leachate and will cause many problems to the water resources.

Australia’s creative industry enterprises to exchange Center (CIIC) released the “creative industries economic analysis report” shows that from 2008 to 2009, Australia’s cultural and creative industries contribute to the GDP has more than agriculture, forestry, fisheries and other traditional industries as well as gas, water, electricity , etc. accommodation and food service industries.
Relatively scarce talent in our country not only in this area, the management of cultural industries operate in a lack of professionals, managers present status quo is not a high level of educational attainment, industry and poor working conditions, low wages, greater mobility industry, etc.

In this way, the shared hardware and software resources and information can be like water, electricity and gas to meet the users’ demands through their terminal equipments and the matched cloud network, cloud storage, cloud security and cloud management.
Those non-common sectoral professional application systems can be constructed in this way.
The new E-government framework should possess the following several points: platformization of the basic network, cloudization of application resources and socialization of professional service

But, owing to the limited professional knowledge, the town residents are unable to obtain reliable information about the advancement, economics, feasibility and other relevant information about the energy-saving technology, resulting in a serious information asymmetry about the quality of construction between the both sides.
The adverse selection about the towns and villages energy-saving housing construction market Owing to limited professional knowledge, as the consumers, the town residents don't fully understand the information they obtained and the level of the energy-saving about the building.
The architecture which the BREEAM uses is a very transparent, open and relatively simple, and the evaluation objects including management, energy, healthy and comfortable, pollution, the use of the land, the ecological value of the location, materials, the consumption and efficiency about the water and so on, to evaluate whether the buildings meet or achieve the standards of energy and water conservation, environmental protection.
The scope of the evaluation including site planning, energy and atmosphere, water saving, materials and resources, the indoor air quality and technology innovation.
It has 14 evaluation indexes: energy/ global greenhouse, the cooling leads the global temperatures rose, traffic (the three indexes belong to “green” index), the use of water, the management of rainwater, the management of sewage (the three indexes belong to “water” index), the pollution of rainwater, diversity of natural resources, toxic substances, ozone depletion due to the cooling, the total waste released, waste landfill (these indexes belong to “venue management” index), the indoor air quality, the user satisfaction (these indexes belong to “using effect” index).
