l The typical coding methods such as water code, level code, abbreviated code, character code and so on , are designed to" the template of coding rules ".
The software interface should have many advantages, such as simple operation, complete information, fluent input method, clear content etc, so that non-professionals can realize specific coding rapidly.
Visual design of man-machine interface will shield the profound professional knowledge and complex programming process.
It is very convenient not only for the professional and technical personnel to design the code specific information but also for information standardization personnel to manage coding rules.

It has five operating modes, air-condition cooling and heating, hot water, cooling and hot water, heating and hot water.
In no hot water supply mode, the tube condenser does not work and avoid the water temperature kept going up and cause risks.
The COP of cooling and hot water is larger than individual cooling or hot water mode, this shows that the energy saving in the cooling & hot water mode is good.
If you choose hot water, when the water in the tank get to 48 ℃, the indoor fan start to work.

Avoid simply for landscape and landscape design, regardless of the specific environment blindly no practical function, water bridge, pavilion, rockery, pillars, flower, greens and so on, or excessive use of tiles paving, this will only result in duplication of landscape.
In addition, while many universities are now training professionals in landscape design, often their experience is not comprehensive enough.
These programs include forestry, which emphasizes on green development, urban construction which emphasizes architecture and city planning and the art institute’s emphasis on professional essays and modeling.
Overall greening can make the microclimate environment better adjusted, as vegetation and water can alter the temperature, humidity, wind, and available shade, as well as improve the quality of ventilation, and reduce noise pollution, green development can also be used to improve the quality of the water, as well as reduced the heat reflecting surface, so that the water temperature of the surrounding environment be improved.
Uniform rules, coordinating layout Greenbelt is an essential part of residential environment of space, but also in the whole city with green system plays an important role, composed of vegetation, ground water, and all kinds of landscape sketch.

Near the water "line", water full enriching, ice crystal or ice layer forms.
When provided protection, the water content in the upper layer has a small amount of increases, but the deeper the water content can be effectively reduced by means of drainage facilities.
For the embankment, although there is no in- layer water problems, but note the impact of water seepage between the roadbed shoulder seams, timely seal the seepage seams or cracks, and exclude water out of the embankment toe through Water bar.

In one word, the chemical weapons abandoned in China have a large quantity and a wide distribution and were often corroded seriously because they were difficult to store and under ground or water for a long period without protection by the butter.
After the burial sites are determined basically by using geophysical methods, investigation on pollution of chemical weapons can be carried out from simple to complicated under the instruction of professional staffs in selected districts to accumulate experience step by step.
Carry to professional labs to analyze in time to avoid emit of volatile substance and influence to test result.
Concrete work should be undertaken by professional units.
In the districts where water or soil have been polluted, determine pollution range and degree, then take regional risk assessment, on the basis of which, put forward measures to manage and prevent collision pertinently References [1] J.

Remove scale: common cleaning methods to removal scale are phosphate,alkali and acid wash.phosphate removal scale is injecting with the 3%-5% trisodium phosphate solution and maintain 10-12 hours, then rinse off with clear water.
Alkali removal scale is applying solution with caustic soda, kerosene and water preparation of hybrid for cast iron parts; use solution with sodium silicate, liquid soap and water preparation of hybrid for the aluminum alloy parts cleaning.
Acid wash remove scale ,commonly used acid wash are phosphoric acid, hydrochloric acid, chromic acid, etc., after use the acid wash to remove scale, then reoccupy clear water wash thoroughly.

Metallurgical secondary cooling of continuous casting based on neural network adaptive system design of water distribution Jun-li Jia1, a, Jin-hong Zhang1, a, Guo-Zhen Wang1, a 1 Hebei College of Industry and Technology, Shijiazhuang City, Hebei Province, 050091 China azhangjinhong2008@126.com Keywords: Secondary cooling water, Dynamic controlling, Neural network Abstract.
Efficient secondary cooling water control level slab continuous casting process and quality are closely related.
Therefore, the artificial intelligence optimization algorithms such as genetic algorithms, neural networks, fuzzy controllers, introducing continuous casting secondary cooling water distribution and dynamics of optimal control methods, the rational allocation of caster secondary cooling water and dynamic control is important.
(3) The traditional formula distribution method The traditional formula of water distribution method can be completed using the formula a static allocation, enter the main was an average speed of the formula, the formula optimization of the parameters based on Genetic Algorithm Using fuzzy control of water or water at a certain speed optimization by least squares regression.
