A1M, which is attached to an Axio Cam camera and a professional soft.
The wood samples have been peliculized with the acrylic binder of 100% concentration and in combination of 50% distilled water, since the acrylic binder is water based.
The dispersion was made of 6 parts distilled water and 1 part acrylic binder.
The same result was also recorded for the solution of 50% distilled water and 50% acrylic binder.
Thus, the concentration of distilled water was increased to 6 parts distilled water and 1 part acrylic binder, when the generation of the aerosol began.

Cracks in the cavern zone, are criss-cross, led to water seepage in many place.
As water gasification, acid will actually gradually grow strong.
Water is the most important factor in corrosion process, actually, stone damage is not caused by the water itself, but the physical or chemical effect interacted with water.
Because once the micro-porous and water vapour channel is closed, with no allowance to drain water from the underground and internal away, cracks, water spots and other lesions will occur.
Nowadays, domestic professionals of antique maintenance are still relatively few, besides, the skill and quality is just under a low level, thus there is need more work to be done to improve this situation.

The flood control capacity is about 2~10 years encountered.
1.4 Present situation of water pollution
Municipal water has been effected by polluted water, decreased self-purification capacity , and deteriorated water quality in Nanchang.
.
At present, Wusha river channel hasn’t set up water quality monitoring station. while lacking of the special water quality monitoring data.
Otherwise, we need to accelerate the construction of domestic sewage collecting pipeline network which can absorb waste water from enterprise units and urban settlement along river, while professional team will be established for keeping clean, its works contain cleaning the dead litter, dust, garbage on the bank and floating on the water surface on time.
These designs stable riverbed, improve ecology and environment, promote self-purifying of water, make river water quality better.
It is changed from over-flow lasher water into thin-layer face water firstly, and declined by grid crushing secondly, the polluted water has been aerated largely in the dissipation of energy, which can purify water quality by aeration.

Bulk Density and Water Absorption.
The specimens were soaked in water for 24 hours and, after that, were weighed while still immersed in water to get the submerged weight.
Water Permeability.
The average water absorption of the tiles with different mixtures has the following results: The durability of concrete depends on its water absorption; the higher the water it can absorb, the more prone it is to water and other harmful ions, which can destroy the chemical stability of concrete [8].

Then at the roof of the camber-shaped region formed by PVC sheet, a water inlet is cut, which allows cold water to pour in.
If the water inside the PVC sheet should be released, just open the two switches at the water inlet.
By the gravitational potential energy of water, water on the ground level is lead to water storage box, is shown in Fig. 6.
In summer day, cold water inside the PVC sheet turns to warm water after the daylight shines on it.
So the warm water can serve as bath water after being stored in the water storage box.

The model
And the circulatory system of the cold side includes the heat absorption water tank which exposures to modules, circulating pump, water pump transformer, radiators and storage tanks.
The temperature of the water in the tank bottom should be uniform and not too high, otherwise the water in the tank bottom may boiled because of overheat.
The water temperature of model 2 is relatively distributed evenly.
This gives us the design direction of circulatory system the cold side; we can add ribs in the tank cavity, to increase the heat transfer area between the water tank internal walls and the water.
Based on the same tank, the higher Inlet velocity of water, the more heat of water tank will be carried away, and the more heat of cold side will be absorbed.

Air conditioning water system
The air-conditioning water system is a large heat exchange with water as a medium to transfer cold or heat between buildings.
Some designers do not make each water loop for water balance calculation, and also failed to take effective measures to press differences between each loop.
Air conditioning water system When the cooling water cross through the cooling tower, firstly use the temperature difference between nature and the cooling water, if this is not enough send a request to re-start the fan cooling, in order to achieve the requirements of the cooling water temperature of the chiller.
The cooling water of the cooling tower is not a separate part, which will run from the cooling towers to the chillers, cooling towers and chillers make a loop, then the contaminated water in the cooling tower fouling in the cooling water system, that make corrosion and moss so that the cooling water flow is reduced resulting in a rise in unit energy consumption.
The operation and management aspects of the majority needed regulation, which requires managers to have a higher level of professional and business skills, therefore it is necessary to the equipment managers and maintenance personnel system of energy-saving operation and management training.

The waste metal cutting fluid is dumped on the ground, down the sewers, or sent to landfills, where it finally either seeps into ground or floats on water surfaces.
And the KOH ionise quickly in water and form strong nucleophile OH- for breaking polar bond that holds the thickener and base oil in waste metal cutting fluid.
But, rising temperature can increase the solubility of solid and oil in water, so, a further increase in the extraction temperature will result in decreasing mass of oil sludge and reducing the volume of the recovery oil.
