The phenomena often appears that sea surface is above land, island is under sea surface and distortion of building inter-island in conflux area of water and land when creating three-dimensional image using fusing DEM and image.
Outlining the main features of the softwear PCI PCI Geomatica is developed by PCI company of Cadana, which has the functions of processing RS image, photogrammetry, GIS spatial analysis, professional graphics, powerful file management features, secondary visual development environment.
Generally speaking, there isn’t this step which modifies DEM in 3D RS image production process, but the study area land and water are much of the possession, if we did not modify the DEM to obtain the 3D images, then the elevation displayed by DEM at the junction and the contents displayed in image do not match, some land sunkenes below the water, some water raises above the adjacent land, and the bottom elevation of all water bodies in accordance with its ups and downs do not match with the actual water height.
Issuesing and Analysising to general practice of 3D Rs image Zhoushan area accounted for a large part of the water body, the DEM in water body is the elevation values of the bottom, while the DEM value displayed in the image is the one of the surface water ,there will be 3 problems if we directly interge the original DEM and RS image to produce 3D RS images .
Modify the principle of modification is that the elevation of the seawater is to make consistent, depression of the land rose up and raised the water falling down, the Inter-island structures returne to normal form.

The window sashes should be glazed, heating, water and electricity should be connected.
In fact, to become a professional mechanized spraying plaster compositions is not difficult.
As a rule, even if the company leases machines with guide, after two or three days plasterers of this company themselves become professionals and subsequently lease only technique.

Investigation on Synthesis Conditions of Silicon- doping Hydrotalcite-like Compounds WANG Lei1, a, XIAO Peng1, b 1 Jilin College of Professional Industry and Technology, China, jilin a wanglei03@163.com,b xp0614@163.com Keywords: Silicon-Doped–HTLc;co-precipitation;synthesis conditions Abstract.
Making up a prescription referenced to the formula of Mg6(Al2-xSix)(OH)16CO3·4H2O, MgNO3 , NaAlO2, NaOH, Na2SiO3, and Na2NO3 solutions were mixed by an experimental ratio, and the mixture was dripped into a flask containing distilled water slowly, Stirred constantly in a pH environment of 8~9.
Finishing dripping, the flask was setted into a thermostatic water-bath for 4 hours.

Design Builder can be easily utilized, so that even a non-professional user can quickly conduct modeling for a complex building .
After the processing of visualization on Design Builder model, 3D model can be output to other softwares and can play a role during the presentation . 4.2 HVAC Analysis Design Builder v3 provides a more powerful and flexible way to access Energy Plus HVAC model, and uses the complete ASHRAE 90.1 baseline HVAC system type to analyze gas load and water route. 4.3 Daylighting Analysis Internationally accepted American Radiance lighting analysis core is applied to map isophotes and calculate the average lighting factor.
Fig 2 The air flow simulation Conclusion Design Builder building software, through analyzing the basic information of project and the difference of building types , develops different technical route strategies and project location; through providing a rich selection library of products, helps designers effectively analyze the built environment; and through establishing a unified data model, completes the computational analysis of energy conservation, simulation of building energy conservation, integrated design of solar energy water heater and architecture, and some relevant simulation work, which greatly improves the design efficiency.

In the study, two types of propolis extracts were used which were prepared in different solvent environment (50 % ethyl alcohol – 50 % pure water; 47 % propylene glycol – 53 % pure water).
Although healthcare professionals need to change their masks periodically, it is known that they do not have the opportunity to change their masks as often as necessary during emergencies [2].
As it is given, the solvent of Extract 1 (E-1) is a mixture of ethyl alcohol and pure water, whereas propylene glycol and pure water were used as the solvent in Extract 2 (E-2).
E-1 50 % ethyl alcohol 50 % pure water 24 hours 40°C E-2 47 % propylene glycol 53 % pure water 24 hours 30°C Table 3.
HPLC-DAD analyses showed that raw propolis extracted in ethyl alcohol-pure water and propylene glycol-pure water media have different phenolic components which lead to difference in antibacterial activity.

It can prevent liquid from flowing into the permeable formation so that the cement is able to keep a proper amount of water, which can ensure the safety of cementing job.
Water-based drilling muds with the addition of fluid loss additive to control fluid loss or improve inhibition often cause large changes in fluid rheology.
The fluid loss of fresh water cement slurry can be controlled about 50mL with 2% P1402.

It is important ecosystems on the planet, with stable ecological communities, wetlands in maintaining water, flood and waterlogging, conditioned air, biodiversity conservation has an irreplaceable role.
Water is an essential element of wetlands in urban wetland park planning should focus on taking into account the water pollution control, and water purification function, enhance self-purification ability of wetland so as to achieve the purpose of the water system to recover.
Water Environment Ecology Landscape Environment Figure 1 Water Wetland Ecological Design In Wetland Park is not only to the local ecological restoration, but also take into account the impact of the whole basin of local wetlands proposed recovery plan for the whole basin.
Most Tinglang built by the water ( Fig. 3 ) built of wood materials.
Landscape was given so many symbolic symbolic meaning, is viewed by the people and the impact of the way of thinking, because people saw the water gushing and nourishes all things, will have a feeling of charity.

Second, the lack of innovative professionals.
Enterprises are lack of senior management personnels who have accepted systematic training and are lack of complex talents who possess both management capabilities and professional skills, multi-skilled IT talent, and research talents to apply technology.
Promote the Integration of Resource Elements to Provide Public Goods for the Development of Industrial Clusters Public goods needed by the development of industrial clusters include: the establishment of industrial belts, industrial park and the base as well as the necessary infrastructure, convenient transportation network and communication conditions, ample supply of water and electricity, a full range of specialized wholesale markets, unimpeded logistics system and good ecological environment.

Since there are no specific waste home appliances recycling base and technology is not mature, a lot of waste home appliances could not professional classified and harmless disassembled.
Some small factories purify precious metals from appliances parts using acid foam, fire and other backward technology, result a lot of waste gas, waste water, waste residues and serious environmental pollution.
Only establishing the bases with mature technology and well-managed, it could achieve professional recycling, improve the utilization of waste home appliances recycling; it could achieve safe disposal of waste home appliances, protection of the natural environment; it could continue to study treatment and recycling technologies of waste home appliances to promote environmentally friendly recycling-based new product development; it could promote the development of appliances industry, the real implementation of the principle of minimization of circular economy, reduce waste at the source.
In transport links, the appropriate and economic transport mode should be selected based on the characteristics of waste home appliances, as much as possible to reduce transportation costs. 3) Classification: Professional classification is an important part in waste home appliances recycling process.
