Therefore, the utilization rate of global energy can be improved greatly if the professional heating systems could be equipped in civil buildings where people live.
Only the professional quality, practice skills, and design standards of design personnel can be improved in an all-round way, a scientific and practical heating design plan can be ensured for civil buildings.
The commonly used heating technologies can be concluded as follows: (1) co-generation of heat and power, which is a comprehensive energy utilization technology using the low-grade heat energy for heating after using the high-grade heat energy of fuel to generate power; (2) concentration heating of small and medium regional boiler rooms, which provide heats for buildings with hot water cycle in coal-burning, gas-burning, oil-burning ways and via regional pipe network; (3) small gas water heater, which is a economical and practical heating solution if the natural gas can be selected as heating fuel material in the newly-built civil buildings; (4) direct electric heating, which is a technology applying all kinds of electric radiator and film indoor, allowing the home owners to make an adjustment flexibly according to the specific requirements of the home owners and possessing a 100% heat utilization rate in end device.

At the same time, the initial conditions of construction and matters requiring attention during the construction phase are integrated and discussed, as well as issues such as the weights of design value, as a whole to consider, to minimize the error between the design and construction. 1 Introduction Energy-saving construction is the construction mode with the target of utilizing resources reasonably and recycled, conserving resources and reducing energy consumption for construction, which means during the process of construction, each part like the planning, design, construction, maintenance and other need to save energy such as water and electric to the maximum degree, and effectively increasing energy usage, reducing energy loss [1-3].
In addition, the progress of the construction need to be deployed scientifically, reducing the consumption of green areas in the water, which is an energy-saving construction method. 3 Conclusion At this stage, energy conservation and environmental protection and low-carbon energy consumption are the inevitable trend of the development of construction project, which needs related professionals in their work continued make reform and innovation, and integrate advanced science and technology, and make improved so as to achieve suitable for the construction.

This can explain why system with photocatalyst suspended in water or fluidized in air has shown the higher efficiency than immobilized one.
Besides, relatively poor initial design even worsened its performance so that some environmental professionals concluded that photocatalytic system had inherent disadvantages.
As a pretreatment step, dipping POF in acetone, followed by washing off remained residue with distilled water was conducted.
TiO2 suspension (5 wt%, pH 4.5) in purified water (Milli-Q, 18M� ) was prepared and dispersed sonically.
This reactor is with both solar concentrator to increase light intensity and water filter to prevent POF from melting (light guided reactor in Fig. 4).

Mountains, plains and hills make up a pattern of 70% mountains, 10%water and 20% arable land.
Yichang is rich in mineral and water resources, famous for its Three Gorges Dam, Gezhouba and other large water conservancy projects, and it is also rich in forest, tea, specialty fruit, chestnut, walnut, edible mushroom and other agricultural products.
As a provincial deputy city, Yichang is a hub of traffic, water transportation, logistics and economic development of western Hubei and eastern Sichuan.
At present time, industry is mainly on technology-intensive enterprises such as water conservancy and chemicals.
Lastly, shortage of professional technical city planner and the confined power on local planning personnel and fiscal department restricts the urbanization development in Yichang.

Currently, there is no suitable product manufacturing standards and professional test equipments abroad.
(2) Taking into account the influence of the water at low temperatures on product performance, it is advisable to increase a length of coil tube before products, which are put in the liquid nitrogen tank to carry on with condensation.
It can filter out possible water, and reduce the influence of the test results; (3) Since the direct relationship between low temperature inner leakage and closure torque, the records are needed for precise measurements of closure torque size; (4) Taking into account the actual operational condition of low temperature cylinder valves, it is advisable to install control values into Dewar vessel, which can really simulate the actual condition of control values when doing the fatigue performance test of products. 4.
Conclusion By researching systematically the use performance needs and safety indexes of globe valves and control valves in thermal insulation cryogenic gas cylinder, finally professional test equipment was developed.

During the operating process, it would establish professional pollution control companies which be provided technical expertise by research organization. 
Include the following content mainly: First, constructing automatic water quality monitoring network in the energy and chemical industry base in northern shaanxi,especially the Yellow River in northern shaanxi.
Third, it is necessary to establish an efficient, professional and reliable environment monitoring network in the base, including drinking water, groundwater, soil, vegetation, poisonous and harmful pollutants, solid waste, etc.

But considering applying the prestressed reinforcement, the plate thickness change little, and prestressed is completed by professional team.

Standards and specifications requirement for the NI mechanical parts material At present, amount the nuclear power plant, including the operating , construction and proposed ones, besides the dominant pressurized water reactor(PWR), the other reactors, such as boiling water reactors, heavy water reactors, supercritical water reactor, high temperature gas cooled reactor, are also under developing.
Supercritical water reactor and high temperature gas cooled reactor adopt high temperature material and the material type adopted in the Russian reactor is according to their own specification.
In the past, the common supplier can’t supply French brand material, except the original professional manufacturers with own smelting.
For individual specifications, small quantities of nuclear material, one can find must have professional scientific research strength of small enterprises to do, on the other hand, you can also find a large iron and steel enterprises in industrial mass production, and then through the establishment of material reserve system and meet the corresponding standards of material inventory, so as to achieve a production, many times the purpose of using.
The pressurized water reactor nuclear power station nuclear island main equipment and materials and welding of [M].

Damaged batteries pose the risk of hazardous material release and shall be recycled immediately under professional instructions.
The electrolyte is a solution of sulfuric acid (35%) and water (65%).
3) How about the influence of the spent VRLA to the air, soil and water?
The mechanism of reaction between batteries and environment, and the potential harm to the air, soil and water shall be settled.
