Comparisons of Laser Cut and Water Cut for Silicon Steel Plate Geng-wu Liu Electrical and Mechanical Department, Hunan Railway Professional Technology College Zhuzhou, Hunan, 412001, China Keyword: Silicon Steel Plate; Cutting Technology; Laser Cut; Water Cut; Comparison Abstract: Silicon steel plate is main material of motor and transformer, and can be produced by Laser cut or water cut.
The silicon steel plate of laser cut and high-pressure water cut are two kinds of new technology.
The demand of water for the machine is to use no hydronium water.
Because the ordinary water contain a number of exiguity grain that cannot melt in water, such as calcium carbonate, manganese, iron, silicon dioxide and so on.
Research on Water cut of Silicon steel plate ICEAMT2012

According to our current teaching methods, the vocational talents who are cultivated in this situation are qualified in their professional field.
Hydraulic engineering technology is a highly practical major course in water resources.
The teaching of water conservancy major concerns more on subject system and knowledge infusion and less on ability training and overall quality education.
There is not enough emphasis on knowledge application, creative spirits and practical ability, and professional training skills are relatively weak, which make students have mature professional skills and hardly adapt to profession changes.
(1)Let construction course teachers actively take part in practical exercises, get experience and improve professional skills.(2)Hold professional skills training courses and lectures.

Recycled concrete crushed and milled to a coarser fraction used as a substitute aggregate in the concrete mix was examined by countless professionals and experts [2, 3, 4, 5], because it is a widely used method of application.
The grinding was carried out without water.
The increase of the amount of water (water/cement ratio) in the mixture is due to the higher demands of FGRC on water.
· More water in the mixture of the samples with the recycled concrete caused an increase of pores resulting from the water desiccation
· Shrinkage of cement mortar with fine ground recycled concrete is influenced by the water cement ratio, i.e. the amount of cement and mixing water

There are also some cases of destroying the surrounding environment of ancient buildings, such as constructing tall buildings, chimneys, water towers, cable cars and cableways within the scope of ancient landscape.
The lack of technical professionals has made the protection work even harder.
Protection Contents and Principles The protection work of ancient buildings must obey some regulars and principles which are effective experiences concluded by many professionals.
Once again, governments should train abundant protection professionals which undertake a lot of responsibility in carrying out surveys, making complete scientific record files, and studying protection technology and maintenance method.

In a modern building, there are a large number of different professional mechanical and electrical equipment, such as central air conditioning systems, ventilation systems, plumbing systems, elevators, lighting and so on and which is characterized by numerous and dispersed.
It is not enough just installed tens of thousands of electricity pieces, water meters, gas meters, heat meters and other energy-saving products to each building.
Intelligent terminals installs a professional, standardized client by middleware implementing data statistics, analysis, display and the setting of data bound value, demand value and links with the background expert database.
Sense layer is mainly composed of various types of sensors, including various intelligent electrical water tables in the building and humidity sensor monitoring environment parameters and so on.
For the users, they don’t need to install the server locally and the professional software.

Engine room staff professional skills, physical conditions, psychological characteristics and other factors will directly affect the error rate.
Specific measures are as follow: (1) Strengthen the crew professional quality education and training.
Crew professional qualities include business skills and professional ethics.
Ship managers should combine with professional features to educate and train crew members, so as to enhance crew professional emotional development, strengthen the sense of professional responsibility, norms of professional technology conduct, reduce the adverse psychological effects and other aspects, meet with the crew competency requirements of “both ability and integrity” eventually
The Safety Assessment of tanker ballast water exchange: (a master's degree thesis).

The spray cleaning equipments include hot-water high-pressure cleaner, pressure pipe and water gun.
The hot-water high-pressure cleaner can adjust the cleaning fluid’s pressure and temperature [10].
The water gun is mounted on the end executor, and is able to spray every part of the monitor.

The product conforms to JC/T984-2005 (China professional standard: Polymer cement waterproof mortar).
The water used was tap-water.
The water reducing agent was 0.5% respectively (based on the cement weight).
Its water resistance was also poor.
The mortar conforms to JC/T984-2005 (China professional standard: Polymer cement waterproof mortar) and GB/6566-2010 (China mandatory standard: Building materials radionuclide limited).

The future of China’s golf clothing will appear in professional way or focus their products on high-grade level.
The ball is easy to corrosion cracking in water during rainy days.
Gutta glue can be softened in hot water.
The golf ball is usually made of a single strand of rubber thread under tension, wrapped hundreds of times around a sac or core containing water, oil, liquid silicone, nylon, or rubber.
A man called JamesⅠwas a professional golf club maker from England as early as in 1603 [5].

In recent years, for the development of green energy-saving eco-building, many professionals are dedicated to research high-tech industrialization of walls, actively develop new wall materials, and explore new forms of building structure [2].
Combine with modern building insulation feature, professionals have developed many excellent insulation wall materials to take place of brick, and used many new technologies and equipment integrated to improve the ability of external wall insulation.
It can effectively solve the thermal bridge effect [5], eliminate the condensation, and cover cracks in the external wall to prevent water seepage.
Because of its unique closed-cell structure, it performance superior resistance to water vapor, simplify construction technology and reduce the project cost.
