The study was carried out by model experiment in the calm water and oblique wave using 6 types of bilge keel variation in its length and width.
The first experiment is roll decay test in the calm water to get damping moment for every the bilge keels variation such as Table 1.
Conclusions Based on the experiments conducted with fishing vessel model in calm water and oblique wave, the common design of bilge keel is able to reduce roll motion.
Considering uniformity reduction roll motion in the calm water and oblique wave, normal size bilge keel for merchant ship can be applied in the fishing vessel.

According to the practical professional requirements for each layer, different transfer functions are chosen to transfer information and produce the required output result in the output layer.
It has thus been widely utilized in natural disaster risk assessment and water resources system modeling.
In a study by Gao Xuemin et al, [3] the quality standards of Chinese surface water environments were examined and several evaluation indexes were selected.
The study referred to the assessment index recommended by the water conservancy industry: standard SL450-2009.

Introduction
Yacht is a recreational tool floating on the water which differs from ordinary engineering ship.
A good yacht is based on stable structure, strong performance, a good person-boat relationship and higher aesthetic design requirements, what’s more, the design need to focus on emotional demands of the people for water leisure culture and yacht styling aesthetic needs and to highlight the symbolic expression of fashion, style, quality, and value, etc.
The yacht unlike ordinary engineering ship, it is a symbol of water leisure life, needs to create a rich aesthetic art form and comfortable and beautiful visual experience to meet the aesthetic needs of users.
It is a high grade of water recreation product, its design has a higher request, should reflect their personality style.
The crowd for a professional and a certain economic strength, the level of education ranging from specialist to PhD degree, involving design profession/ industry, shipbuilding/ machinery industry, advertising/ media/ fashion/ tourism industry, academic and research institutions.

Bone also contains water which
is very important mechanically [1,5,23,24,25].
Water accounts for approximately 11 % of the volume of hydrated bone.
Thus, changes in water content have a significant effect on mechanical properties.
Noninvasive measuring technique that would allow quantifying these parameters in a robust manner would be of great value for the medical professionals.
For a two dimensional plate immersed in water we can change the transducer spacing or the water layer thickness above the plate to change the TOF of the signal from emitter to receiver.

The measurements of the acidity of the samples (pH values) were performed with AD8000 Professional Multi-Parameter pH-ORP-Conductivity-TDS-TEMP Bench Meter, with a measuring range of -2.00 to 16.00 pH, a resolution of 0.01 pH and an accuracy of ±0.01 pH.
The hemihydrate PG powder is mixed with Ca(OH)2 and water to obtain the mixture.
The PG-Ca(OH)2 mixture is blended with water and cured.
As far as the particles of PG of type II are smaller, more water is required than for the mixture of type I.
After the 1st day, press-formed specimens are immersed in water for 5 min., in order to enhance the crystallization rate.

Community waste water and sewage can be deal with near community sewage in usable huge water process system of steel plant.
The iron and steel enterprise produces a large amount of waste gas, waste water, and waste residue with usable heat from raw materials, coking, fritting in the production process of iron-smelting, steel-making, casting in succession and rolled steel.
For example, concentrate on water treatment and water-saving technology mainly, the treatment technology of exhaust gas (especially flue gas desulfurization) preventing producing and treatment technology of other harmful gas.
At present, from the view of energy-conservation, cleaner production and environmental protection, the water-conservation, closed circulation and sewage treatment technology, hot water community of water of the steel factory supply technology are worth causing the special attention.

Because of different mixture styles there are different names which depend on the water content: viscous suspensions which contain little water are called slaked lime or fat lime.
In this case, the mixture is heated so that water evaporates and the suspension boils.
Here, carbon dioxide is taken from the air and discharged in water.
On the other hand, it is highly alkaline and should not get into soil or waters.
This "top layer" of the wool fiber is capable of absorbing water in the form of steam, however, it cannot absorb liquid water.

In China, the conventional planning generally has enough time, but the post-disaster reconstruction planning starts when people are facing severe life threat, thus is required to be completed in the shortest time, which could lead to a lack of related technology and professional support.
Before post-disaster reconstruction planning starts rolling completely, scientific professional investigation and poll evaluation need to be conducted to inspect regional difference, truly understand the actual needs and intends of victims, and firmly avoid the pursuit of forms or “achievement project".
