In water flow movement similar conditions, the velocity scale of the Freund's similarity and resistance similarity is inconsistency, and the flow resistance is the function of bed material grain size and flow intensity.
In the model design, the basic similar conditions include the water flow movement similar and the sediment movement similar conditions.
It should be pointed out, natural river water, sediment and bed sand sizes are varied, so no matter what prototype incipient motion velocity determining methods are approximate.
(1) The primary and secondary selection of water flow movement similar conditions is same as the bed load

Changing temperature will increase air and water temperatures, reduce frost days, increase sea level, and glaciers, permafrost, and sea ice.
In 2004,The low energy office (LEO) building which is located in Putrajaya, built as a evidence and demonstration project by the Ministry of Energy, Water and Communication [8].
On that basis, this study focused on the building sector professionals and policy makers to find or to improve systems that consumes renewable energies such as solar energy and wind that uses nonrenewable energy and electrical reduction in Malaysia and Asia Pacific countries’ residential buildings.

The spirit of ensuring basic living supplies affected object can food, water, clothes to wear, shelter, sick to get timely treatment principle requires reserve rice, clean water, clothing, resettlement places. 
Local Government in conjunction with the actual situation of the development of scientific and effective contingency planning and make the appropriate resource reserves work, strengthen emergency rescue exercises work and professional training for local governments and related organizations and the masses can occur when unexpected events respond effectively to lay a solid foundation.
It is inseparable from the study leader, the leader of the study, there are two main ways: one is through professional training, kind is self-learning.

· Lifeblood facilities: wire and cable, water pipes, gas pipes and communication facility
Because the users of the system probably were not particularly professional personnel, so we achieved two functions.
The advanced query could do professional query.

In paper, the first part introduces the working principle and working flow of ABS automobile braking system; the second part establishes the EBD control mathematical model of automobile ABS system; the third part uses Unigraphis software to carry out the numerical simulation, Unigraphis is a professional model and structure analysis software, through the modeling and analysis of ABS, it can obtain braking system temperature and braking force, to provide the theory reference for the development of ABS system.
expressed as: (5) Through the EBD generalized coordinates, they can get the generalized matrix position: (6) For the rigid mechanical system, the form of vector can be expressed as: (7) For the rigid body motion constraints, they can be hinged constraint, their mathematical expression is: (8) The velocity and acceleration constraints can be expressed as: (9) Research on the Automobile ABS Unigraphis Simulation Unigraphis is a professional

Before the construction quality control 1.1 The selection criteria of the construction unit Unbonded prestressed concrete construction is very professional, the requirement of technology and the operation is very high, according to the provisions of the relevant provisions of Technical regulation of unbonded prestressed concrete structures(JGJ/T92-93)[2] and Construction technology policy [3],should entrust construction unit that have related level of qualification to construct. 1.2 Do the technical clarificaiton work seriously 1.
Corrosion-resistant and lubricating grease Should have good chemical stability in -20℃~+70℃ temperature range, in high temperature does not flow, no fission no crisp at low temperature, has a certain toughness, has no erosion influence to the surrounding materials, can prevent water, damp proof, resistant to corrosion, have good lubrication performance, reduce the friction resistance effectively. 3.
Conclusion The prestressed concrete construction is a very professional job, have a high requirement to the construction materials, equipment, the construction technology, construction personnel technical level, so its have certain difficulty to guarantee construction quality.

With the development requirements of modern water transport, constitutes a form of jobs moving from labor-intensive to technology management type changes.
Study of the human resource of waterway system Through the research on long-term work in the channel system talent expert interview, combined with the author's many years of work experience, clear an ideal professional and technical personnel with ability quality factors, build human resources evaluation system, as shown in Table 1.
To ensure the randomness of the sample and to avoid errors caused by small sample, we make anonymous questionnaire survey between the Yangtze River Waterway Bureau belongs grassroots units and professional and technical personnel, a total of 200, finishing the last 189 valid questionnaires survey data.

With every new video, the audience intently, suddenly their mouth spray water column on the screen, this is an exciting time.
The combination of modern design and architectural innovation has been proven to be a successful art form, a new culture of communication for artists, cultural professionals, arts organizations, cultural institutions, government agencies, enterprises, and all the media, the public, and increased , public interaction space.

Using computer-aided design work can via the Internet more effectively coordinated with architects, also structural engineers, as well as water, electricity, roads and other professionals work closely with the garden project designer, in a large engineering requirements.

Furthermore, because all low-strain analysis software available thus far includes defects, judgment accuracy is still based on the experience of technical professionals.
