Results of this study indicate that CCUA is an efficient indicator for measuring the sustainability of the pattern of urban expansion, which can assist the urban planning process of professionals and facilitate the decision-making process of local government.
In the meantime, we can’t afford unprecedented scale of urban expansion/sprawl caused by rapid urbanization, which has occupied large amount of area of other land use types (i.e. arable land, forest, water body), degraded the quality of the environment and ran a risk on the food security.
Four LULC types - urban land use, arable land, forest, and water body (Tab. 1) (since the scale of green land in the city was small and had the same spectral characteristic as cultivated land, thus they were all assigned to arable land ), were identified using unsupervised classification, and the base map was displayed in rainbow colours.
Water body Includes rivers, lakes, and reservoirs.
With the procedures illustrated in this study, the assessment of urban spatial patterns is of immense help for facilitating decision-making or urban planning by local governors or professionals.

As a newly, useful, and potential unconventional water resource, reclaimed water can be used broadly to improve the unsatisfied situation of water utilization in Tianjin.
The general approach in this research is to collect information through survey of experts and interested parties, expert interviews, together with a review of comprehensive literature including chronological statistics yearbooks and various professional documents.
Reclaimed water use project in TEDA. a.
TEDA reclaimed water plant.
By 2010, six water supply centers for public reclaimed water will be built in the central city.

The tracks are mostly built in the holiday villages, science and technology parks, parks, water parks or scenic spots near the TV stations.
The bold intervention of professional guidance in sports can not only promote scientific level of such programs, but also accelerate the construction of intangible sports industry by implanting sports goods advertisement and the upgrade of tangible sports industry by developing sports apparatus, bringing in new developing space of sports advertising and sports goods industry.
In the program “Boys and girls, Go” by Anhui Satellite Television, its track in the first season was located on the south bank of Swan Lake, and then moved to the Pleasure Island (Aqiu Bay Water Park) on Fanhua Road in Hefei.
The tracks of the program “I am the Best” by Zhejiang Satellite Television is in Leyuan Water Park of Hangzhou.
So we need to take advantage of sports professionals to design the tracks in accordance with the law of human body motion so as to promote the competitiveness of the program, need to implant the professionalized concept of sports apparatus production to guarantee the humanization of sport’s level design, and need to start from participants’ clothes to promote the publicity and the sale of sport’s goods.

The main machine of pipe hydrostatic tester includes front beam, filling water calipers, exit gas calipers, moving trolley and frame beam etc[3-5], as shown in fig. 1.
The water pressure is produced by the main oil cylinder and side oil cylinders set on the moving trolley.
A big axial force from the high pressure water is acted on the filling water calipers and the axial force is transferred to the front beam through the filling water calipers.
front beam filling water valve filling water calipers exit gas valve exit gas calipers moving trolley frame beam Fig. 1 Main machine structure of pipe hydrostatic tester FE models building of the front beam and the moving trolley of pipe hydrostatic tester The nominal force of the pipe hydrostatic tester in the study is 32MN, which can be used to test steel pipe of Φ406-1626.
In the study, the geometric models of the front beam and the moving trolley are built with professional CAD software SOLIDWORKS and then they are lead in professional CAE software ABAQUS to built their FE models.

The information database contains not only the geometric information, professional attributes and status information used to describe building elements , but also includes the status information of non-component objects (space, exercise behavior and its like) .
Green Building and Design Concept Green building refers to the practice of improving the efficiency of the resources used by the building (energy , water, and materials ) while reducing the building’s impacts on human health and the environment.
Save water resources, including green water conservation . 3) Returning to nature.
As a professional simulation and analysis software of natural architecture’s lighting, through establishing relatively accurate digital model that is suitable to simulate indoor lighting and setting a number of different simulation parameters, it can assist the design or research.
Meanwhile, its model can be saved in the formats of many major professional analysis softwares, so that it can be output for accurate simulation analysis .

Therefore students spend a lot of time on studying TADS and overlook some professional courses, which badly affect the growth of professional skills [1].
Nobody, who doesn’t have excellent professional design skills, can create a good design works.
It’s just like a castle in the air without essential professional knowledge and excellent creativeness in actual design.
Therefore, the basic purpose of TADS teaching should be focused on the enhancement of comprehensive ability in architecture design, including both the TADS leaning skills and the professional knowledge improvement.
The teachers should keep the abreast of the latest development of it and improve their own ability both on professional knowledge and teaching skills.

Then we changed cooling water flow.
Data of the cooling water flow Experiment 1 2 3 4 5 Cooling water flow(L/h) 500 400 300 200 100 Results and Discussion The result is as Table 3, Fig. 1and Fig. 2.
The distribution of impurities by different cooling water flow Fig.2.
But When Cooling water flow arrived at 400L/h, if increased cooling water flow, the impurities contents would increase.

But with foreign countries, the information management system, industry standards and professional supervision institution as compared with domestic in risk management, there are a lot of problems: （1）The related laws and regulations is not sound.
At present, many industries have corresponding professional technology level exam qualification examinations and industry.
Such as accountant from job seniority card, audit from job seniority card, construction engineers, accountants and auditors, engineers and other related qualification and professional level certificate, and certified public accountants, registered plant engineering and other professional supervision practice certificate.
But for the information of the personnel qualification requirements, professional skills to identify and relevant supervision industry practice requirements are not standard, is still in the explorative.
Because the supervision industry informatization employees professional level is low; The information of the authorities in charge of supervision industry is not clear, have a plenty of science, have a plenty of work in the letter hall, chaos; Supervision company service effect is not obvious, the sense of responsibility, coordination ability is poor, professional morality low, appear even and joint deceive the phenomenon of the manufacturer.

Defects on some of them and unfortunately even accidents of some cases of bridge objects, mainly recently published by media, related to corrosion of prestressed reinforcement awoke interest of both professional and wide non-professional public related to its durability.
Recent breakdowns of some bridge buildings related to reinforcement corrosion steered attention of mainly wider professional public towards points of issue of corrosion of prestressing reinforcement and at the same its anti-corrosion protection [2], [3].
Defects and Breakdowns An important impulse that attracted the attention of not only professional public to the issue of corrosion of steel prestressing cables, appeared in relation to an unfortunate collapse of the footbridge over Vltava river in Prague.
Penetrating water in some cases also evidently migrated in the core or on the surface of wires of PSC tendons, pouring down by gravitation in the direction of longitudinal slope of the bridge deck.
Humidity condition in ducts and slots of the footbridge in Troja was for sure affected by floods during which the footbridge twice fully disappeared under the water.
