The Pivotal Technical Components
The CISDI packaged soft-reduction technology for slab continuous casting involves several professional fields, such as metallurgical process, mechanics, hydraulics and automation, which would be described as below respectively.
The core function of this model is to exactly predict the heat extraction and solidification status of slab by finite difference heat transfer simulation under given casting operation condition, and its simulation results are important theoretical reference data for the reasonable design of secondary cooling water system, the precise calculation of compound heat transfer coefficient of each second cooling zone, the exact predictions of temperature field & solidifying shell thickness of slab under steady operation condition, and the correct debugging of CISDI_CCPS ONLINE[5].
In the second module, the effective casting speed of secondary cooling zone is introduced to make consideration about cooling history of slice element, and the secondary cooling water is dynamically controlled by the corresponding target surface temperature curve of slab.
By means of the positive cooperation between CISDI and Liusteel for more than one year, the whole debug job was completed smoothly, in which, all the significant control functions have been realized normally in turn, such as the remote roll gap adjustment, the dynamic secondary cooling water control, the static soft-reduction control and the dynamic soft-reduction control.

Due to differences in professional background and accomplishment of the responsible person, the data provided were confused, inaccurate, even lacked, which resulted the poor applicability of the basic statics during the investigation.
The plant coverage is great.There are winding tree-lined paths and small outbuildings, or water.
Other green space The green space that have directly effects on quality of urban ecological environment,resident’s leisure life,urban landscape and biodiversity conservation.It includes the scenic area, water source conservation, country parks, nature reserves, forest parks, scenic forests, urban greening belts, wildlife parks, wetlands, landfill restoration green space,etc.
There were different calculation for the water in park.

(2) Wide area of scattered water distribution.
Through a unified planning and design, by renovation of existing water bodies, good water landscape can be shown.
Ecological Restoration is an effective way of managing eutrophic water and maintaining long-term stable and healthy development of water.
Aquatic plants can not only absorb nutrients in water and sediment, but also can get a variety of biological clusters to their surface, resolving organic matter and nutrients, increasing water transparency, and improving water quality.

For 'Coral Star', the wavelength around the 950 nm water absorption band was also found to be useful for firmness predictions [15].
Hong et al. adopted nearly same method with Guo to predict the sugar content, water, weight of Chinese pear.
The results showed that the ANN model could predict water and sugar contents with coefficient of prediction of 0.996 and 0.94 respectively.
Therefore, development of multispectral system based on optimal wavelength which was extracted by hyperspectral imaging system will be potential to implement in a real-time detection of agricultural products with the development of fast, efficient data analysis algorithms or professional software.

It is a homogeneous mixture of a water-soluble phenol-formaldehyde prepolymer brand FRV-1 with the product OP-7 (surfactant) and aluminum powder brand PAK-4.
Heating of the raw material was carried out by the contact method when the container with the prepolymer was immersed in a heated liquid (water) with constant stirring of the prepolymer and control of temperature indicators. 3 Results and Discussions For the beginning of research, it was necessary to determine the effect of the starting components and their content on the main properties of phenolic foams.
And also, the toxicity of phenolic foam is reduced by removing free phenol and formaldehyde monomers together with water vapor from the foaming composition.

Normally, technology is the achievement from different professional fields and it is abstract, hard to
be understood, but customer needs products which are intuitive, easy-operated and emotional
satisfied.
Such cases of physical contradiction are quite common in industrial design, for example, we need hot water to make a cup of tea, but meanwhile the cup must be not too hot to be held by hand; here come a pair of physical contradictions.
Some designer takes advantage of separation principle to design a cup by separating the area of hands holding part and water containing part of cup to fulfill the function.
Without direction, innovation or creativity would be nothing but bring much more business rubbish to society, so, direction to designers just like water to fish, it performs critical action.

The Seafood street of Zhuhai gongbei, Tianjin City Food City businesses base on the professional market to maintain its own operating characteristics, thus avoiding the vicious competition in the same “niche”.
Just think, if Beijing does not have the alley, Shanghai does not have a lilong, Guangzhou does not have Xiguan big house and arcade, Suzhou does not have a small bridge, flowing water, white walls and black tiles…well, what personality at all for the folk architectural style of these cities there?
New city is a modern city and the old city is to maintain the south of Yangtze River style: small bridges, water, and people’s charm.
Small town in the south of Yangtze River, bridges, water, people, is Zhouzhuang in the history of construction on the natural environment natural select, which is “niche” choice.

For immersion liquid, distilled water was used and a single pan balance used to do the measurements.
Equation 1 shows the relationship which helps in calculating the densities: d=dwwawa-wl (1) where the mass of the glass sample is represented by wl when it is suspended in distilled water and the mass of the glass sample is represented by wa when it is in air, (density of water, dw = 1g cm−3 at 23°C).

Because of the common brick masonry has good water absorption, to ensure the mortar do not condensed too fast which would influence the construction, fully watering humid in planted before the injection, but in the planting aperture should not have flowing water.
