                Steam type appliances work like this: First, make the water convert to steam, then recoverability to change clothes in physically (the surface of the flat) with the steam temperature and humidity [7].
In this stage, 19 kinds of fabrics were made pleats first with reference to the AATCC 128-2004 standard [12], then the garment steamer of Midea YGD30A1 was used to finish the ironing experiment, and last two trained professionals evaluated the smoothness appearance grades after ironing.
When rating the smoothness appearance grades after ironing, two trained professionals must not interfere with each other.
The smoothness appearance grades in Table3 were the average of the results of two trained professionals.

                Bearing radial force is small, mechanical strength and installation of the bearing is relatively low accuracy requirements; 2), magnetic agitator without the mechanical seals,  to achieve zero leakage fully 
3.2 comparison of Mechanical agitator and magnetic agitator installation 
Mechanical agitator installation required by professional trainers, you need professional installation tool, the bearing clearance, shaft straightness and other requirements are very high.
(Import agitator requires measurement of the new bearing clearance, the new bearing clearance in the 0.12-0.25mm, jacket and bearing no circling phenomenon. axial deviation of not more than 0.10mm, straight off the greatest degree of shaft center distance of 1mm / m) Magnetic stirrer overall installation, without requiring deviation,the installation work is mainly connected flange bolts, without professional training.
Magnetic agitator without mechanical seals, mechanical seals do not change the workload, the bearings lubricated with water cooling, cooling water into the slurry, carbide bearings, high hardness, small friction, thermal properties, and normal operation of the life of more than five years.

                According to the survey, all kinds of existing public building in Shenyang energy consumption situation have the following characteristics:
 Office building
In addition to heating energy the office building consumption mainly includes: lighting energy consumption, office electric equipment power consumption, integrated service equipment system power consumption such as electro thermal boiling water reactor and elevator ,air-conditioning power consumption as well as the information center and other specific function device system power consumption etc.
Building energy consumption density is between 215.09 and 398.69kWh/ (m2·a),compared with the standard arcade building energy density of 200 ~ 300 kWh/ (m2·a) ,we found that the energy density is high in commercial building of Shenyang, energy waste is very serious; only 60% of the commercial building electricity and water using system is measured separately, through the form of feedback information display, there are 80% departments reflect that the energy saving effect of sub-metering in general.
In order to save operating cost, create greater economic benefits, more than 80% of the hotel launched a series of energy saving and performance optimization about the equipment which use energy, the optimization model is divided into "Self optimization", "equipment manufacturers optimization" and "professional energy-saving company optimization".70% of the hotel established technical archives of energy-saving operation, but it is mainly for central air conditioning and power supply equipment, while still the lack of lighting and other aspects of energy equipment .
Raising the level of operation of energy saving management The owners of governmental organization office buildings and large-scale public buildings and the property management units should build special energy management organizations; they must employ professional people to do the work.
Intensifying the work about energy-saving and reconstruction of existing buildings We suggest Shenyang to establish a professional energy service organization .The owner or the users of the public buildings can authorize the energy service organization to have a scientific demonstration on the necessity, feasibility and profitability of energy-saving, then they could choose energy management contract to implement is.

                Solar water heating further reduces energy costs.
Water Efficiency Reducing water consumption and protecting water quality are key objectives in sustainable building.
Waste-water may be minimized by utilizing water conserving fixtures such as ultra-low flush toilets and low-flow shower heads.
Point of use water treatment and heating improves both water quality and energy efficiency while reducing the amount of water in circulation.
Regulation and Operation As a result of the increased interest in green building concepts and practices, a number of organizations have developed standards, codes and rating systems that let government regulators, building professionals and consumers embrace green building with confidence.

                There is also severe situation of water pollution and waste of water in China.
Through deep processing, the water can be used as landscape water and green irrigation water for constantly reuse.
When it is rotated loosely, bulk water or water column will come out.
This initiates people to conduct deeper and more refined professional research with full use of modern high-tech achievements, breeding new ideas and new technology.

                It causes the information between all professionals and all stages separated.
The same one component element only need to be inputted once, then groups of workers can operate the component element in different professional angle, which can provide bottom support for the collaborative design. (3)The designers can use the function of collision check in BIM design software to find conflict timely, which can thoroughly remove hard collision and soft collision to optimize the configuration scheme of pipeline.
The designers can make use all kinds of professional analysis soft wares, such as Ecotect.
On the basis of simulating, it can analyze and calculate energy consumption, water consumption and carbon emissions of building, in order to help value management team to optimize the design scheme.

Abstract.
There are many weak links in the traditional urban management systems, mainly as follows: information lag, passive management, overlapping functions between professional management department and bull management [1].
The database is a key session of gridding management for hydropower construction project consisting of the following parts: 1) The geographic information database and the professional database is a resource base of gridding management for the hydropower construction projects [4].
But the degree of information of the overall hydropower industry is low and the maturity of the professional information systems meeting the demand of gridding management is on the low side, so the management of projects needs to enhance the overall level of industry information.
To achieve gridding, professional and fine management need more data to support and improve data sharing.
