In the process of terminology extraction, we must ensure the validity and uniqueness of terminologies, remove the redundancy and ambiguity, makes the terminologies provide a standard for the communication of professional concept.
Firstly, the basic terminologies are extracted, namely the most basic terminological concepts in the professional field.
They are usually the most common and basic professional terms in the field and serve as first-order ontology.
For example: (1) move fast; (2) cold water; (3) drill hole.

Introduction There are almost 11,600 large public buildings existed, Bird's Nest, Water Cube, the National Grand Theater, the new CCTV building are the most representative buildings.
In order to examine the public’s understanding on the crisis knowledge and crisis plan, professionals’ ability of crisis solving, crisis management feasibility and reliability. e) laws and regulations protection A5, is to determine the rights and responsibilities of chief executive officer and emergency management personnel in the process of emergency through the development of relevant policies and regulations. f) institutional arrangements A6, means that government establish the daily response and emergency management agencies in accordance with state emergency provisions, and so specify the duties.
process of public emergency, to master the basic information of the incident and quickly make appropriate decisions in the shortest possible time. c) public emergency response B3, is the public response capacity and emergency state when facing public emergencies. d) crisis control B4, stands for the measures taken by government to response to public emergencies, preventing the sudden expansion of public events and the increase of loss of life and property. e) Crisis information feedback B5 , is in the process of crisis management ,to collect, analyze, publish and report relevant information, and to ensure the accuracy and reliability of the information, and then to provided accurate and reliable foundation for crisis judgment and treatment. f) resources integration B6, is in the process of crisis handling , the use of centralized mobilization of human resources , finance, and materials .It also stands for the production and allocation of emergency supplies , transportation capacity of professional

Circulating cooling water.
In the running process of circulating cooling water, it should improve the professional quality and sense of responsibility of water quality managers, so that they not only know the importance of circulating water in production, but also fully understand the factors that affect impacts the circulating water quality, and effects of water quality on corrosion of the network equipments.
Because the circulating water systems are mostly open systems, and water evaporation is continuous during the process.
So only scientific sewage discharge according to test results of the cooling water and continuous water supply, which makes the conductivity of circulating water drop by 2.5-3 times, can reach the goal of water conservation, and also avoiding the corrosion .
Water treatment chemicals[M].

Practical verification of the accomplishment of this requirement during the flotation test of the vehicle is very difficult since to conduct a test, there is necessary to be available both water with corresponding parameters (an adequate width and depth and required current speed) and conditions suitable to perform a test (approach to water, suitable entry to and exit from water, environmental aspects …).
In general, it can be stated that for a permissible speed of a current can be considered such a speed of a current at which the vehicle can safely negotiate a water obstacle in a required place, to overcome this water obstacle by flotation in a desired direction and exit the water obstacle in a pre-determined place.
These are water obstacle width, water obstacle depth, current direction, bed and bank characteristics, bank height and slope and type of plant-cover.
From the viewpoint of maximum permissible speed of a current, two methods to assess the amphibious vehicle capability to negotiate water obstacles are presented in this paper: · Analysis of the amphibious vehicle movement during its flotation in a current under recommendations of the current professional literature; · Comparison of flotation capabilities of the evaluated vehicle with capabilities of fielded amphibious vehicles that are long time in operation.
It is seen that vehicle loses its capability to safely negotiate water obstacle even at much lower speed of a current.

Solar energy is suitable for small-scale water pumping in remote areas where the demand is regular, such as for drinking water, but it may also be used for irrigation.
Water is more precious than the rarest of diamonds.
Photovoltaic (PV) devices (solar cells) are being used to power water pumps for potable water supplies in world.
The social and institutional matrix within which solar pumping occurs may be more important than technological factors for the success of a project, rural dwellers must be involved in the planning of the system and the building of the local infrastructure, although professional support must generally be brought in from outside.
Although the original purpose was to provide clean drinking water, the water was eventually used more for domestic because the villagers preferred the taste of water from well.

The numerical results indicated an increase of 29% (non-isothermal case) and 18% (isothermal case) in the recovery factor when water was injected on the reservoir surface as compared to the water internal injection in the reservoir.
Amongst the existing techniques, the injection of water stands out as one of the most used [3].
A similar behavior can be observed in the dislocation of the injected water to the lower layers of the reservoir; however, the area invaded by hot water (Fig. 4a) was wider if compared to the isothermal situation (Fig. 4b) after 24,000 hours of injection.

The evaporation from open water remains a difficult process to measure or estimate.
Results depicted in Figure 3 show a good agreement with the experimental measurements and can be used in water management plans to estimate evaporation from reservoirs and water bodies.

For the destruction of classified storage media[3], by professional equipment to its cutting crushed, crushed residue particles required to meet national security standard BMB21-2007 the relevant provisions.
With the increase of the number of overwrite, it will be difficult for the original data completely recovery even using the professional data recovery software.
Data delete method can't completely clear data, use some special software recovery tools can make the data reduction; Strong degaussing method, burning high temperature destroyed method, physical damage method, chemical corrosion damage method these several ways need professional destroyed equipment or chemical reagent, and require manual intervention to remove storage media data destruction from buoys, it is unrealistic for marine environmental monitoring buoy data storage module.
If the positioning display buoy location is still in our territorial waters under the jurisdiction of the scope of the tube, just at the right time make buoy homing; If can’t make buoy timely homing in the short time or buoy has flown out of the sea areas, and worry about the buoy stored marine environmental elements data is illegal agencies to obtain, can make data destruct through the data overwrite way.
