But because the magnetic field strength generated by eddy current is very weak, and the electromagnetic wave in sea water is easy to be absorbed by seawater, the detection range is smaller.
We first imaged the lakebed in the water areas without steel tube to test the penetration depth of SAS.
Because the sound wave has penetrability and the sediment exist apertures, after the sound waves go through the water and hit the seafloor, a part of sound waves will continue to spread the depths of the sediments [5], and will be reflected back one after another, different echo will be reflected back when the sound wave hit the armoring layer of SOFC.
FIG.3 3-dimensional imaging of certain bridge pier Problems and solutions of InSAS detection The application of InSAS in the detection of SOFC is different from the general study of InSAS, it has more professional and targeted, some improvement and optimization for SOFC detection need to be done.

Taian is also the middle place of the travelling hot route of “one mountain, one water and one sage” in Shandong Province.
One water refers to Jinan City, which has many springs.
Dongping should highlight the Shuihu Culture, speed up the tourism development of Lake Dongping and build the large tourist holiday resort with hills and waters.
Another very important thing is that tourist practitioners must have a wide range of knowledge and the superb professional skills.

The following intermediate layer compositions were developed (refer with Table 1): - alumina cement: crushed fractionated high alumina refractory at a mass ratio of 1: 3 and the fractional composition of high alumina refractory material 0.25–0.63 mm; 0.63–0.80 mm; 0.80–1.25 mm; - aluminous cement: crushed fractionated high alumina refractory at a mass ratio of 1: 3 and liquid sodium glass, introduced with mixing water in an amount of 5%; - aluminous cement: crushed fractionated high alumina refractory at a mass ratio of 1: 3 and liquid sodium glass, introduced with mixing water in an amount of 10%.
Indicators of block foam glass quality with a protective and decorative coating (processing speed 10 mm/s, thickness 4000 µm) № Quality indicators Dimension Quality indicators values 1 Adhesive strength MPa 0,74 2 Cold resistance Сycles 50 3 Microhardness HV 740±20 4 Acid stability – Spots and stains are absent 5 Water resistance Hydrolytic class III The studies results of operational factors indicate a high quality vitreous two-layer heat-resistant decorative coating with a wide color grade.

To insure the fully evolution of pearlite and gain different lamellae pearlite prior to LSP, all specimens were vacuum annealed at 1050℃ for 15 min, then put into the salt bath furnace at 600℃, 700℃ for 30 min, respectively, followed by water cooling outside the furnace.
After that, the sample surfaces were polished with SiC paper with different grades of roughness, followed by cleaning in deionized water.
A water layer was used as the transparent confining layer and the professional Al tape with a thickness of 100 μm was used as an absorbing layer to protect the sample surface from thermal effect.

Starch itself is weak and easy to absorb water, so it requires blending with other biodegradable polymers to make the starch toughening and strengthening and meets the requirements of foam preparation.
According to the deliquescence character in the hot water can divide starch into amylose and amylopectin, dehydrate glucose structure of amylose mainly unit to passα-D-(1,4) indican key conjunction, the structure is shown as Fig.1.Straight chain part of amylopectin structure is coupling byα-1,4- indican key, embranchment part is coupling byα-1,6- indican key, such as Fig. 2 showing.
Polyvinyl alcohol, viny alcohol polymer, poval is shortened form PVA, the chemistry structure type is [C2H4O]n.PVA is a kind of water-solubility complex bond, the agglutination mechanism is that impregnate volatilizes while heating.
When standard residual>2, the observation point is excrescent, for these points should combine professional knowledge to deal, the results in this analysis are all in the range of the error margin and satisfied with the requirement.

Since the 1990s, China began to promote the development of sustainable architecture, and puts forward the concept of sustainable construction with Chinese characteristics-“energy and land saving buildings ”, the main content including energy, land, water saving, material saving, emphasis on sustainable development, in order to deal with the contradictions increasingly urgent population, resources, environment and industrialization, urbanization, rapid economic growth.  
In this evaluation, the definition of green building is “the whole building life cycle, to maximize the conservation of resources (energy, land, water saving, material saving), protect environment and reduce pollution, provide health, application and efficient use of space for people, symbiotic harmony with the natural building” [2].
Make full use of the natural landscape and the natural energy, water saving and land saving and material saving, pollution control on site, reduce the influence of the surrounding hydrology, wind power, lighting and ecological diversity, establish people-oriented green building system of biological and non-biological systems.
In respect regional culture environment, construction, under the premise of human relations, integrated rational organization of construction technology, using cross multidisciplinary cooperation, more professional, the curing and application of methods and means of implementation, coordination system combined with indoor and outdoor environment building body, achieve the pleasant, comfortable target.

They play a certain role in increasing the income of the farmers, but the majority of them also bring water pollution, solid pollution, air pollution, noise pollution, radioactive pollution and soil pollution.
In the history of China, the water way is an important mode of transportation.
Water pipeline, road lamp, waste disposal facilities and fire facilities, all these should be fixed based on keeping environment of ancient town.
Increasing literacy, professional training and health education can constitute important steps to improve autonomy and self-capacity of ethnic groups in order to break the poverty circle.

Some of the hydropower stations are not professional, and they do not have the qualification to exploit the hydraulic project.
Water is an important clean energy, so the first task for government is to follow “Renewable Energy Law” and “Water Law” to distinguish the responsibilities between the department of water exploitation and water management department, and define clearly series of rights, such as the plan of water resources, exploitation and management, attornment, examination, etc.
So far, other countries are going to the stage of water management instead of water exploitation.
There is no doubt that the whole world would reinforce the water management in 21st century which means that water would be used according to reasonable management.

When using the ion exchange method, the resulting quality of purification allows the use of purified water from heavy metals in the water recycling cycle.
Collection of information and development of a project with its subsequent implementation and technical support requires a professional approach in each individual case.
Therefore, when purifying water, it is necessary to partially desalt it, in other words, to correct all salts dissolved in the water.
This is especially important if purified water is in the circulating water supply, then sulfates will be a source of hard sulfate scale.
