In the process of the biological farming, the breeding biology and the breeding facilities have a great impact on the water exchange and other dynamic factors, and restrict the water exchange.
In the hydrodynamic of the ocean, we used the Princeton Ocean Model (POM) which is the Physical Oceanography professional model [3, 4, 5, 6].
The experiments Modify the water level.
The boundary water level is derived from the Atlas of the Oceans and get from the actually measure in general.

Because of high-rise buildings and large construction area, if safety problems occur, the consequences would be disastrous.Project unit and construction unit attached great importance to the problems, and specially invited experts in building structures to investigate and analyze the site, and held discussion meetings of the professional and technical personnel to analyze the seriousness,urgency and dangers of the current problems.
Finally, in order to ensure the safety,the project unit has commissioned a professional reinforcement firm to detect and identify the project.

It is known that adobe buildings are subjected to deterioation by weathering, especially by wind and moisture (either from excessive rain water, rinsing ground water or high humidity).
Basing myself on the study of Brown and Clifton [6], adobe is principally made of: clay: 10-15%, silt: 10-15%, sand: 70-80% and water: 25-30% [6].
Calcite is a carbonate mineral which not only reduces the extent of water absorption in bricks (porosity decrease), but also leads to plugged pores even the smaller ones due to precipiation.
It is also not easy to find experienced professionals mastering the adobe construction methods (architects, masons, etc.).
Conclusion Adobe bricks treated with ecological and low-cost composants followed by natural fibers is an effective solution for the water absorption and weathering, cycling of wetting and drying.

The wine aged with oak chips is different from the wine aged in oak barrels in terms of cost, but mouth feel and aroma of two wines are similar, it is difficult to distinguish for non-professional customers.
The applicability of the E-nose analysis technology for wines and alternative potentials for professionals are discussed.
Fig. 1 Schematic representation of the electronic nose system of PEN3 The temperature of the water bath was maintained at (25 ± 1) °C.
Each sample was incubated for 15 minutes in the water bath; then, a 5mL aliquot of each sample was placed into a 20mL glass jar.
However, by head-space dehydration, the elimination of water from wine samples became possible and significant aroma differences appeared.

Introduction Nowadays, enantioselective separation covers an important area of analytical chemistry of relevance to a wide variety of scientific professionals.
The solid was washed with deionized water and dried to give brown powders.
The residue was added ice water, and then solid was precipitated.
The yield of target product was strongly affected by water, so anhydrous condition was very important.

Current situation In recent years, the fire water supply equipment has been greatly improved in water supply capacity, equipment body, and the degree of automation.
Fire water supply equipment occurs these problems owing to human factors: the power supply of fire water supply equipment is interrupted for a long time, the normally opened valve of water supply equipment was mistakenly Off (The system can not water), long closed valve was mistakenly opened(the water provided by the water supply system will reflux) ;and more important reason is water supply equipment corroded, damaged and so on.
Second, when automatic checking, the speed of pump is low and the pump will not out of the water.In t,athe fire intelligent inspection system check the water pump and the circuit,at the same time the pipe and water spray will not be damaged.
Fire inspection control cabinet can also determine the water capacity of the pump, record water pump operation fault timely to remain the intact state of fire water supply equipment.
If use the manual inspection, fire maintenance personnel often can appear sloppy or lack professional knowledge, so that people can't invest scientifically fire control system fault.

Introduction The construction industry in worldwide is one of the main contributors to the depletion of natural resources and a major cause of air and water pollution, solid waste, deforestation, toxic wastes, health hazards, global warming, and other negative consequences.
China’s green building certification system takes much more reference of the LEED certification system, which is much similar to LEED, evaluates and certifies building environmental performance with a variety of prerequisites in six categories of land savings and outdoor environment, energy savings, water savings, materials savings, indoor environmental quality, operations and management.
Consumers are being educated about the benefits of green building; product manufacturers are increasingly aware of the environmental benefits of their products; builders are learning about new techniques and technologies that purport to reduce environmental impact; and lenders, insurers, municipalities, code officials and design professionals are reinterpreting their roles in terms of green design objectives.16 In the United States, contractors need to fully understand the categorization of LEED prerequisites and credits which have the potential to influence their existing construction project management practices, and they need to provide input to focus on these LEED credits and requirements in green building execution.
Chinese rating system breaks green building into 4 categories roughly equivalent to the LEED categories: Land-Saving, Energy Saving, Water Saving, and Indoor Environment.
Green building poses a series of new challenges to building design and construction professionals in China.

According to this, certain spectral ranges, which contained useful absorption information, were determined based on the absorption characteristics of triglyceride and the absorption interference of water in serum.
Besides this, there are two strong absorptions near 1450nm(7000cm-1)and 1940nm(5000cm-1) which divided the whole spectral ranges into three parts and we just call them “water windows”.
Experimental samples.A total of 87 serum samples, with the known concentration values of triglyceride, were prepared by professional doctors.
Obviously, the first two principal components representing not less than 94 percents whole spectral information, we can identify from their shapes, are almost of the contributions of the water absorption.
For this reason, it is necessary to eliminate or reduce the interference of water absorption while determinate the constituents in aqueous solutions.
