The J-lay methodology is the prime technique for laying pipelines in very deep waters.
The J-lay tower is equipped with tensioners or collars holder, which is used to hold the suspended pipeline in water.
Reel-lay is Suitable for shallow to ultra-deep waters, and has a very high production rate.
China has several S-lay vessels, but they are only suitable for shallow water.

(7) Water reducing agent (SP): The water reducing rate is 30%, and it meets the requirements of “Concrete Admixture” (GB8076-2008) and “Polycarboxylic Water Reducing Agent” (JG/T223-2007)
(9) Water (W): The water meets the criterion of “Standard of Water for Concrete” (JGJ63-2006).
It is because that limestone powder with fine particle and smooth dense surface, which scattered between the cement particles, plays the role of deflocculant in the hydration of cement, which makes the fluidity of SCC improved [8], and T50 tends to decrease as well as T700L; What’s more, the fine powder makes the volume ratio of powder to water of the concrete increased, so, the segregation and weeping reduce obviously and BJ reduces gradually.
But with the increase of the limestone powder, it needs to absorb more water, and the density of paste increases, the fresh concrete becomes sticky, which makes the slump flow decrease and BJ increase.
The hydration of cement is accelerated by limestone powder at early ages, and the water of the cement paste is consumed too quickly, so the early-age shrinkage of SCC is larger with mixing more limestone powder.

Experiment part Experiment instruments: Electronic balance, beaker, electric heating furnace, constant temperature water-bath, mixer, Hall trough, Hall trough rectifier, electric drier, scanning electronic microscope (SEM).
(2) Add 500ml water to the 1L beaker, use electric heating furnace to heat it to 80°C
(5) Move the beaker to the constant temperature water-bath, and stir it at 70°C constant temperature for 24h, after settling 24h, filter it and obtain the brightener.

For example, dragonflies need the aquatic plant growing in proper water depth so that their larvae can climb and outgrow; some water birds, one the one hand, like building nests near water, one the other hand, they like rest on the revetment with no plants and seeking food in the water.
As the professional in the development, landscape design in the conservation of biological diversity plays a decisive role in the environment.
Control on water level The control on water level not only benefit the water landscape management, but also the sensitive control on water level is the simplest and most effective tool to govern the wetland plant.
In winter, the island over the water surface can accommodate the wildfowl.
Burning The controlling method of burning is often used to manage the zoological marsh and puddles of water in the water landscape.

Introduction Dam is a hydraulic engineering building that partitions off a watercourse or water mass by a septum for lifting the water level.
The chart of water level’s changing Marks on the chart show the process of water level's measurement by developed controller.
The chart shows that as long as the water level does not change dramatically, the system takes measurements by default, but when the water begins to increase or decrease, frequency of polling also increases.

The surveys also revealed that most professionals are resigned to the fact that they will not be able to access complete information, and that they will more than likely have to conduct a site inspection so that it is possible to recreate drawings and reverse engineer the building.
The missing link here is the fact that, even with cloud computing, design professionals will still not be able to determine what information has already been produced without first tracking down the owner of that information.
Maps of utilities, such as water and power, can be used to design these services within a building, and then the additional demands on those utilities due to that design could be predicted by the Building Information Model.
For example, a water authority may only wish to grant a private organisation access to a view-only image of a network such as a PDF.

As information and processes are migrating to the Cloud, Cloud Computing is drastically changing IT professionals’ working environment.

As indicated in "Yellow Book of the international situation", in recent years, drinking water crisis caused by water pollution has accounted for a large ratio of China's man-made disasters .Over 140 water pollution cases have been taken place in China since the benzene contamination of the Songhua River in 2005 , about one water-related pollution case every two or three days.
According to the statistic data, about 60% of Yangtze River, China's largest river has been polluted.The water quality of yellow river, the important water source of north China is also deteriorating, about 40% of which has lost its function.
Excessive discharges of industrial wastewater and lack of urban sewage treatment facilities are regarded as the main source of water pollution.
First, inadequate qualification of environment authority officers such as lack of practical experience in law enforcement, inadequate understanding of legal knowledge, fear of difficulties in law enforcement , lack of the overall version sectoral interests or local interests, weak responsibilities, or even violation of professional ethics, dereliction of duty, trading power for money limits the enforcement effect.
China's newly revised "Water Pollution Control Law" stipulates that enterprises will be fined one million at most for illegal wastewater discharge.

Using common pump the water often easy stopping the pump because of water velocity is less than the pumping water speed, the residents living inconvenience, also affecting the service life of the pump.
Development of electromagnetic vibration pump has a direct practical significance to solve the residents living water intake in northwest area of difficult problem.
Its working principle is: after the power is switched on, alternating current produces alternating magnetic field in the stator around, when the magnetic force is greater than the elastic plate assembly, elastic, rotor suction, suction a shift to the left, the chamber volume between the water inlet of hinge and hinge increases, pressure is reduced, the water hinge is opened, complete absorption process.
Get widely application using reciprocating pump of this type in small reciprocating pump. 2) Vibration pump is self-priming function, use more convenient. 3) Vibration pump is especially suitable for household, the flow head range to meet the household demand, power of small, low cost, water area for household water intake pump, due to the well water storage ability is poor, in order to ensure continuous water supply, electromagnetic vibration pump because of its superior performance, is the ideal choice. 4) Electromagnetic driving vibration pump first electromagnetic drive mode and volume pump combined and applied in household, its speed can reach 10 below, is a breakthrough of low specific speed pump. 3.
However, with the drastic increase of water demand, in the nineteen twenties, low-speed piston pump flow is limited gradually replaced by high-speed centrifugal pump and rotary pump.
