The areas of waterways are unpredictable, so the weather causes the water floods and landslide happen easily, and if the system can be warming immediately, it can also avoid unnecessary losses.
The professional personals propose a neural network Levenberg-Marquardt algorithm combined with MATLAB program to predict landslide surface displacement [6].
The water level sensor The water level sensor use to detect the reservoir, the river water level exceeds the set standard, and the professional personals use the measuring results to determine whether there levee break may, LED access indicator lights display flashes.
LED lights can display the result of the detection system, 8X8 LED matrix binary with flashes of principle, such as the flashing of the LED matrix on condition G sensor, infrared body sensing situation is also flashes to indicate that the water level sensor situation also flashes said, 00000001,00000011, flashing the said rainfall measurement condition, the following is to determine the identification of the LED lights table.

The development of new compositions of composite materials based on the industrial wastes from regional enterprises and aimed at the corrosion protection of construction products and structures is an urgent task for construction and technology professionals.
Water-soluble polymers introduced in small amounts (up to 3 %) in the form of powders or water solutions in the course of concrete or concrete grouts preparation exert mainly a flexibilizing effect.
The FTPS polymer composition is not soluble in water.
FTPS is a hydrophobic substance, its particles are poorly wetted with water.
The organosilicon water-repellent modifier KOZh136-41 was used in the present investigation.

In the solar energy light and heat systems, an integrated HVAC system uses the sun’s hot water and air conditioning system, as well as the heating of water through the recovery air conditioning heat.
In design and construction, the intelligence of computer and information technology professionals, from Tongji University, were also involved in the "Bamboo House".
They work with an evacuated tube collector to provide domestic hot-water [17].

Study of Close-range Photogrammetric Method using Ordinary Digital Camera Yingdan Mao Department of municipal Engineering Zhejiang Water Conservancy and Hydropower College Hangzhou, China 31852028@qq.com Key Words: three-dimensional laser scanning; deformation monitoring; point cloud Abstract.With the progressive development of photogrammetric technology, the digital photogrammetric method based on the basic principles of digital imaging and photogrammetry has replaced the traditional photogrammetric mapping method and has been widely promoted and applied.
With the development and progress of photogrammetry technology, the popularity of digital cameras, and the rapid increase in performances, the photogrammetric method of non-professional digital cameras has broad application prospects in the engineering construction monitoring and scientific experiments, etc. fields of application [3].
It uses the technical methods of the non-professional equipment (that is, the non-special equipment used for photographical measurements) to collect the data, and uses the existing computer software system to acquire coordinates for pixel points.
It is a type of better software used to acquire coordinates for pixel points among the non-professional equipments.
There must be large distortion errors in the processing and installation of general digital cameras, thereby the distortion of the acquired digital images is larger than that of the acquired images by the professional measurement camera.

The plant pest control, water and fertilizer management and maintenance, and sanitation management are in place.
There is a shortage of water and fertilizer and the management is extensive.
There are some places in the roads and parks which need to be cleaned. 3.3 Greening management and maintenance technical staff are not professional The quality of greening management and maintenance personnel is low.
The water body garbage in the park is timely cleaned, the cleaning situation in the green space is improved and the maintenance and renovation of trash can are completed.
The saving-orientated green space management and maintenance strategies are put forward to reduce the costs of management and maintenance, such as improving soil quality and green waste utilization; establishing scientific and reasonable performance evaluation and compensation system, and create a healthy competitive environment; intensify the cooperation with the professional technical departments to carry out technical advice and technical collaboration.

Researchers and construction professionals have adopted lean manufacturing concepts and strategies in the development of lean construction principles.

Talent structure and professional structure were unreasonable, professional technicians and senior engineers were rare.
Chemical synthesis, biodegradable plastics can be made by biodegradable synthetic polymer through chemosynthesis, which exists in the aliphatic polyester and water-soluble polymer.
Natural substances, The cellulose, starch and other natural polymer materials can be modified chemically, its strength, water resistance, anti-aging, thermal plasticity and other properties are close to the common plastic’s.
Appropriate and efficient environment-friendly inks can be actively developed, such as the solvent-based inks has been phased out now, water-based ink and efficient UV curing inks have been used recently.
Meanwhile, a water-based UV inks has been developed by combining the clean water-based inks and UV inks [6].

The platinum printing method is use the photosensitive nature of the platinum salt to produce images, the earliest use platinum chloride and hydrogen potassium mixed to get photographic emulsion, and now add sodium ferric oxalate. 3.2 The process recipe Platinum salt process sensitizer formula: Group A: ferric oxalate solution Group B: mixed solution of ferric oxalate and potassium chlorate Group C: chlorine Asia Platinum Potassium / tetrachloro platinum solution of sodium Developer formula: Platinum developer a (warm tone developer): mixed solution of anhydrous sodium carbonate, anhydrous citric acid and hot water Platinum developer two (micro-warm tone developer): a mixed solution of potassium oxalate and hot water Platinum developer three (cold tone developer): a mixed solution of ammonium citrate and hot water Cleaning fluid formula: Mixed solution of disodium EDTA and hot water 3.3 About the negatives and photo paper Platinum works of negatives should have a higher
The paper generally choose fine texture of rough fiber printmaking paper or water coloured paper.
Because of the complexity of the process, the success of a platinum works depends not only on the photographer's experience, intuition, but also have good luck, a platinum works to bring us a visual shock and the admire of the professional spirit.

The total of islands is about 200 and there are still countless reefs scattered under the water.
They lie beneath the water level and are very close to the surface of the waters.
These tasks need be performed by professional salvage personnel and special equipment.
Presently, the excises are mainly in the Xiamen-Kinmen waters.
