China has not yet establish professional ice model test facilities. 
The propeller thrust is to be greater than this channel resistance plus the open water resistance.
Though forced self-propulsion ship model test to get the thrust coming from propeller at 5 knots, estimated ship resistance in open waters and ice resistance in corresponding ice level through the open waters ship model tests at 5 knots.
ROW is the resistance in the open waters at 5 knots.
Model ice is formed from saline water of 0.7% salinity, in the ice making process, ice water in the towing tank is in a super-saturated condition , continuously release the tiny bubbles. 

Jack-up platforms suitable for different soil conditions and the large sea water depth range.
There are 117 constructed and constructing deep-water jack-up platform in the world, among which 69% of deep-water jack-up platform work in the 106.7 ~ 121.6m water depth, and two work in the 137.5 ~ 152.4m depth.
For piling operations in the deep-water poor marine conditions, jack-up platform plays an irreplaceable role.
The underwater rock groups of drilling are adopted by the using of jack-up offshore platforms, and deep-water rock surface is grinded.
Now, multi-function jack-positive offshore platforms are moving to deep water, large-scale, professional, intelligent, dynamic positioning, and multi-functions.

To meet the requirements of LEED, the amount of sediment could not exceed 1mg of sediment per liter of water.
Water tank trucks are responsible for taking care of reducing dust generation by wetting demolished material and internal roads.
The sweeping activity also takes care to generate the least amount possible of dust, always throwing a little water before passing the broom.
Figure 18 - Images of sprinkling water on roads by water tank trucks and sweeping for dust control at construction site of the Maracanã.
In the LEED certification is not considered the learning process of the construction companies and involved professionals as a criterion for scoring.

It can work on a local area network, to support multi-user, multi-platform system, and also can coordinate with several finite element processors such as EDS [8] and other professional products supplied by many CAE suppliers [9].
PEG is a kind of water-solubility polymer, and includes series of polymers with different molecular weight.

On the other hand, the integration of mathematical modeling and mathematical experiments teaching model to the teachers to master a variety of mathematical software, data processing software and common modeling methods, to promote teachers' professional proficiency, teacher are also participated in the mathematical contest in modeling in guiding the students accumulate experience and method of research-based learning, teaching and research teaching, collect the relevant teaching material, case and course plug-ins, these resources and experience in the application of mathematics experiment and the university mathematics teaching, can promote the university mathematics teaching reform and improve teaching quality.
The mathematical model is often used to solve the practical problems such as: population model, traffic model, environment model, ecological model, urban planning model, water model, the model of using renewable resource, pollution model and so on.

Under this mode, the enterprises can concentrate much more on their core businesses, which can help to improve their professional levels and their competitiveness among other competitors.

In the life cycle of one project, the total design project construction, the related organizational measures, professional construction design and material testing organization design are called construction method.
Fig. 1 The steam turbine generator installation quality influence factor of Beijiang power plant Table 1 Influence reasons analysis of the steam turbine generator installation quality Steam Turbine Generator Installation Influence reasons Personnel The artificial measuring error, resulting in lower detection precision, for example, shafting centering error is large, the wheel connected error is large; Material At present, the main support of millions of units is mortar cushion block, the ratio of grouting material quality, the base unit water quality and the strength of bearing steel and other materials will influence the bearing settlement, resulted in the big unit vibration; construction methods There are bias because of the construction process or technical requirements, for example, in the Beijiang power plant #1 unit, a lot of weight larger auxiliary equipment foundation designed as a single form, and caused equipment settlement serious because of the soil problems; Construction

For this case , the car designers of vehicle electronic control system designed to increase the fault selfDiagnostic function modules. 1.1.1 The basic principle and composition of the automobile self- diagnosis Self-diagnostic module is targeted at a variety of sensors to monitor electric car (such as : water temperature sensor ) ,Itself and various actuator electronic control system ( such as relays , etc. ) , the failure to determine precisely for these three，Kinds of objects .
However, due to limited microprocessor memory , so the diagnosis of projects subject to certain restrictions , but not more complex fault diagnosis , so people in the research and development of newer and better self-diagnostic system . 3 ) Multi- vehicle diagnostic system In order to expand the diagnostic capacity and self- diagnosis function vehicle diagnostic system in the late 1980s Ford's vehicle diagnostic OASIS, Feng Yang Diaqmonitor diagnostic systems , such as Nissan's Consult were born , these systems function more complete, but more expensive professional and technical requirements, and the diagnostic criteria are not uniform , and thus its use and maintenance are also subject to certain restrictions .
