EI not only includes the concept of urban green space system, and include all system which can provide the natural service, such as large scale landscape pattern, natural reserve, forestry and agriculture system, the urban green space system, water system and the historical and cultural heritage system, etc.
The way to ensure security pattern is to take landscape processes, such as the expansion of cities, space motion of species, the flow of water and wind, the spread of the disaster process and so on, as the processes that can implement landscape control and coverage through overcoming the space resistance.
Ecological corridor is mainly composed of ecological structural elements such as vegetation eco-system and water eco-system, etc.
The final spatial pattern of regional ecological infrastructure should be the result which is jointly discussed by professionals, policy makers and the public.

However, there is a professional gap between the field of microclimate and urban form studies and the urban form design practice, which impedes the transformation of research achievements from the former to the latter and has an impact on the orientation of the research issues.
This leads to the fact that such knowledge is mainly grasped by technical experts and professional software, and it is difficult to be converted into the design instruments which can be accessible to the designers. 2.
This helps narrow the professional gap between this field and design practice.

Bromate in drinking water appears as a by-product formed in the process of ozonation or chlorination of bromide containing water [2].
Bromate in drinking water could occur by water treatment with sodium hypochlorite produced by electrolysis of bromide-containing salt.
Bromide concentrations in seawater are above 65 mg/L, in fresh water from trace to 0.5 mg/L and in desalinated waters up to 1 mg/L [2].
Experimental An ion chromatographic, metal-free system (IC-850 Professional model, Metrohm AG, Switzerland) controlled by Metrodata MagIC Net™ software and equipped with 858 Professional Sample Processor, sample filtration system with a 0.2 µm regenerated cellulose membrane, six channel injection valve, low pulsation high-pressure pump, chemical suppression and CO2 suppression, eluent degasser and conductivity detector was used.

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.

It is tough to improve the amount of the clients of the venues which service the professional team because of the special clients, so the other ways of realizing the low carbon operation should be explored.
The control of the consumption of electricity energy includes refrigeration, lighting, air condition; the control of the consumption of heating energy includes heat supply, hot water.
The carbon compensation system should be established for the professional sports team using the high carbon venues.
For example, the member of the professional sports team could call for the low carbon conception by welfare AD, or plant the trees.

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

Reinforcement Analysis of Wanjiakouzi Arch Dam Using 3D Nonlinear Finite Element Method WEI wei1,a, JIANG Qinghui2,b, YAO Chi1,c, XIE Tao2,d 1State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, Wuhan 430072, China 2School of Civil Engineering, Wuhan University, Wuhan 430072, China aweiwei_276@qq.com, bjqh1972@yahoo.com.cn, cyaoc51@yahoo.com.cn, dtseaser@163.com Keywords: Wanjiakouzi hydropower station, arch dam, complex foundation, 3-D finite element method, reinforcement.
Water-retaining structure of the station is a roller concrete double hyperbolic arch dam, the foundation of which is at the elevation of 1285.00m.
At the Wanjiakouzi dam site, the water flow direction of the river is between 25°and 30°, river surface width is 20m~33m, river bottom elevation is 1295m~1300m and the angle between rock strike and water flow direction is greater than 70°.
It can be concluded from Table 4: Table4 characteristic values of dam stress with different calculating schemes Principal stresses With reinforcement Without reinforcement Upstream face 1.57 1.32 -4.68 -4.45 Downstream face 1.07 0.84 -5.95 -5.75 (1) The maximum principal tensile stress value is 1.57MPa without reinforcement measures, which is greater than the limited value 1.50MPa in the design specification for concrete arch dams (The Professional Standards Compilation Group of People′s Republic of China.
