As we know, the FA pool is usually covered with water to prevent contamination, in order to prevent water infiltration underground, the impervious layer must be laid on the FA pool bottom, and lead to FA be in saturated state for ever.
Usually FA is divided into two types: low oxidized and high oxidized, because of its activity, it maybe used as cementing material together with cement. 1.2 Chemical Composition FA is the kind of water sediment with grey or grey White.
The proportion, bulk density, fineness and specific surface area, water viscosity standard of physical characteristics from FA, which reflect its hydration degree and it is also a important parameters. 1.4 Activity FA’s activity generally refers to its volcanic activity, the FA with more activity in hydration reaction process, the ability of generating gel performance hydrate is strong. 2.
The pile is made by the mixed the FA in the pool with a certain amount of cement, and made the weak foundation become a certain intensity of high quality foundation with hard form and water stability. 4.
Quality control and inspection 5.1 Quality Control Professional workers must be in strict accordance with the procedures.

Generally, sensory evaluation of tea quality is estimated through the judgment of the professional tea tasters according to five evaluation elements, namely appearance of both dry and infused tea leaves, aroma, liquor color and taste of the brewed tea liquor [2].
For each sample, 3g tea was infused with 150mL freshly boiled distilled water for 5min.
Distilled water was used to rinse the sensors between the measurements.
Then, 0.5mL distilled water, 0.5mL phosphoric acid buffer fluid with PH value of 8 and 0. 5mL 2% ninhydrin were added into the volumetric flask.
After the mixed liquor was heated for 15 min, it was cooled and was diluted to the mark with distilled water.

The essence of method is an inclined steel plate with water cooling [5].
The slope was cooled by a water circulation system.
The water cooled slope was used to promote nucleation on the plate.
The machined ingots were isothermally treated at 565 ºC for 5 min in a medium frequency induction coil and then quenched into water at room temperature.
Clemex Professional Edition image analysis program on the microstructure photographs was used to obtain the grain morphology such as volume fraction of primary α-Al particles, spherical diameter, sphericity rate and liquid phase percentage. 3.

Steam (steamM) is simultaneously added for adjusting the H2/CO ratio by water gas shift reaction.
In this study, the heat released during the methanation process is recovered to heat cold water (waterR) and then generate steam (steamR) at 150 °C and 1 bar.
The crude SNG produced by the methanation unit is cooled to about 40 °C and partial water contained in crude SNG is removed by condensation.
The CO2-lean solvent leaving FT4 flows to a dehydrator (DH), where partial water is removed.

So facilities and equipment consists of power supply system, water supply and drain system, heating supply system and gas supply system
While decrease in ground water level and influences from surrounding environment are for the later type, of which influence are mainly new projects in the neighborhood.
So the following items are the factors that influence application environment: high temperature, strong wind, decrees in ground water level, neighboring environment, and things like acid, alkali and salt

Professional competence is divided into competence at the sites of energy consumption in the building (numbers in parentheses indicate the status of professionally qualified persons on the date 09.20.2013) [5]: thermal protection structures and buildings (202), heating and hot water preparing (125), ventilation and air conditioning (16), wiring and building mounted lighting (37).
Polish legislation has made the criteria for U values and the maximum energy needs for heating, ventilation and hot water preparation binding.

Fourth, it is the unreasonable use of water resources.
Surface water resource is shortage in Baicheng city; the production and living water to a large extent rely on groundwater.
The Sandstorm impact on residents’ health Harm to human body for Sandstorm Sandstorms are known as particulate matter from professional angle, its harm to human body related to its size and shape.
Finally, from daily protection of residents during the sandstorm, most residents can take some effective measures such as reducing out, close the doors and windows, accounting for 28%; go out wearing gloves and scarfs, 27%; clean indoor dust, 21%; frequently hand-washing and drink more water, 23%; but, most residents take single protection mode and only a handful of people achieve all-round protection.
Secondly, we should drink more water which can timely replenish lost moisture, accelerate the metabolism of a variety of waste and toxins, and do well for skin care and body health.

In recent years, they have attracted more and more attention from the scientific and professional communities and concern from the public awareness due to the increasing frequency with which they occur and the death tolls they claim.
Flood control system was mainly consisted of water tank, pipes and flow control valve.
The water level of the underground water level test tube and the length of dry beach surface are recorded after each certain interval.

Development of polymer mortar composites [4] stems from some needs of construction, public works professionals and materials for energy efficiency in buildings.
Acidic environments, likely to be aggressive for concrete, start with pure water, then extend to fresh water loaded with little or much carbon dioxide, next to acid rain, and finally with inorganic and mineral acids, including wastewaters [8].
After the cure period of one day in water saturated with lime, the specimens were removed and they were kept in an environment with a temperature of 20±2°C and a relative humidity of 60 ± 5% up to 28 days (control medium).
The test-tubes were cleaned 3 times with fresh water, to remove the mortar and/or altered composite, and then were allowed to dry for half an hour.
The low quantity of calcium nitrate found is due to its high solubility in water.
