Analysis of water, drainage in thermal power plant Fig.1 A typical thermal power plant water distribution The typical unit in power plant water into the circulating cooling water system, ash water system, cooling water system, industrial chemical desalting water system (boiler feed water system), desulfurization water system, life and fire water system and reclaimed water system
Ash water system of power plant is second water and water consumption system. 
Fire water should be indoor fire water and outdoor fire water and calculation
The miscellaneous water many, including watering road water, green water, repair water, room miscellaneous water, washing water, coal handling system of coal humidifying water etc.
Summary Water saving relates to thermal power plant boiler, steam turbine, the power of hydraulic, chemical plant, power plant ash and environmental protection, professional, in water-saving process must be the com., consider the overall effect of water saving; water saving technology in thermal power plant including water, reuse, treatment, reuse, emissions and other links, use a variety of water-saving technology combined to become the development trend of water saving technology in thermal power plant. 

According to the energy professional assessed estimates, each year the ineffective domestic cooled water wasted in the whole country can reach at least more than 100 tons, which is equivalent to five medium waterworks’ year-round water yield.
Design Structure and Working Principle This system mainly consists of hot water pipe, temperature sensor, control switch, water-saving box, pressure-regulated suction device, water-mixing valve and cold water pipe.
Then through pressure-regulated suction device 5 the water in water-saving box will go into the water-mixing valve 7 meanwhile the cold water from cold water pipe 8 will go into it too.
There they will mix again with hot water from hot water pipe 12 and goes to solenoid valves 1 and 2 to go either out of shower nozzle or into water-saving box.
It makes it possible in the negative pressure area to imbibe the water in water-saving box with atm press to go into the water pipe

Quality Evaluation of Specialty Employment for Engineering Education Zhenhua LIU Department of Municipal Engineering,Zhejiang Water Conservancy and Hydropower College,Hangzhou Zhejiang ,China liuzhh@zjwchc.com Keywords: Engineering education, employment rate, dimission rate, specialty matching rate, specialty employment-quality index Abstract.Employment quality is the core indicators of specialty or discipline about engineering education reform effectiveness.Evaluation indicators of specialty employment includes mainly employment rate,specialty matching rate, dimission rate.Specialty employment-quality index is presented, the article lists the mathematical expressions in order to facilitate application.
Figure 2 shows that the overall employment rate of graduates is on the rise in China, the social demand for graduates is relatively large because China's rapid economic development needs for large numbers of professionals.
The specialty matching rate indicates a measure of the graduate career interests and specialty,it is an important basis for the evaluation of professional personnel training.
Acknowledgments This work is supported by education and teaching reform projects of Zhejiang water conservancy and hydropower college in 2012, the young and middle-aged teacher training,and is also very grateful to MyCOS Institute.

RFID antenna production using ink-jet method can use water-based conductive ink.
Water-based ink composes the main conductive nano-metal particles, solvents, surfactants, stabilizers and other additives.
Outlook of Water-based Conductive Ink Printing RFID Antenna It is reported that comparing to the traditional manufacture, the cost of using water-based conductive ink printing each RFID tag can be reduced one-tenth, down to $ 0.004.
As indicated by a professional institute, the market capitalization of conductive inks will be three times as the current market by 2015.
Furthermore, the water-based conductive ink for printing RFID antenna will have broad prospect.

The design and construction of the stiffening steel truss bridge is a complex and large-scale professional program.
Especially for decision makers, they don't have the ability to read professional drawings and lack spatial imagination ability for the designed project.

The scenario method intends to build on the premise that those who can directly control details of housing products including developers, marketing professionals and designers, must interact with potential homebuyers.
Stages of Housing Development Process - Stage 1: Planning and Development Developers and marketing professionals usually identify a target group of homebuyers for a development at the outset of development process, attributing specific needs and preferences to them.
It is equally important to increase the storey height to improve the layout of plumbing installations, particularly for additional horizontal connection to replace the conventional vertical connection of electricity, water and gas [6,7,8].

The solar water heating system, the gas turbine's closed cooling water system and the phase change material for cooling of reefer container are the objects of engineering investigations in the third chapter.
This edition will be helpful to researchers and engineers whose professional activity is related to materials science, machinery and biomedical engineering.

Water for fishing rafts that are close to the harbor is provided by the pipes connected to land.
The unorganized water & electricity transportation and the disordered wires and water pipes could bring great potential safety problems.
Currently, the offshore villages are only built for the professional fishermen who work and live on the sea.
