The other part explores the change of the diffusion coefficient with different carbon contents by water quenching to save the organization in the solidification.
The rest were used for water quenching.
The water quenching began when the specimens cooled to 1120℃, and the time interval was 25 seconds.
All these samples then are analyzed by professional image analyze software to obtain the average diameter of graphite nodules.

It is a high-concentrated liquid product, water soluble, non-toxic, non-corrosive, and non-flammable.
On average varies from 0.6 to 2.0 MPa [1], which shows apparently low values but viable building that has since monitoring of professional technical responsibility.
Several factors contribute to this variation of resistance: soil characteristics; type of stabilization; craft production; amount of water in the mixture; drying process among others.

For instance, in a professional football game which is called the world top sport, a great number of fans and spectators are gathered in the competing spot within a short time, leading to a crowded city and traffic jams with sharp increase in vehicle exhaust, and each day, a great deal of living waste is produced in the court and other places in the city by the crowded, which increase the labor by a large amount to clean the waste and badly pollutes local environment.
Water sports such as motor boats and water skiing cause pollution to local waters.
As can be seen in Fig.3, polluted water and rubbish produced in touring is scattered everywhere.
Fig.3 The polluted water and rubbish produced in tourism Environmental Problems Resulting from Golf Playing.
The toxic chemicals from the used fertilizers and pesticides eventually flow into ground, nearby ponds, lakes, rivers or ocean, which makes the nearby and underground water resources badly polluted.

Introduction
Under soakage effect, the water-soil polymer-composite composed of incompact substance on slope flow along the slope which forme the slope debris flow.
Compbell holds that slope debris flow is a type of shallow landslide essentially, while, the shallow landslide is caused by reduction of soil shear strength because of the ascending pore water pressure[1].Thomas K.
(1) Strength attenuation—microcrack silding nucleation stage In rainstorm state,surface water infiltrates into redbeds, molecular force between crystal lattice layer reduces because of infiltration,crystal lattice expands.The volume of rock and soil mass on slope expands after its clay mineral crystal lattice saturated for poor permeability and good water retention of redbeds.
In this stage,the extensive speed of crack expedites,meanwhile, rip crack appears on slope,whose direction is approximate to perpendicular with the maximum gradient direction.Surface water infiltrates into cracks,which engenders big osmotic pressure[11].As well as the expansive force of clay mineral increased,which accelerates the formation and transfixion of crack,the debris flow body exists local glide shown in Fig.13

The properties of RPC can be improved by reducing the amount of water, removing all of the coarse aggregate , using highly refined silica fume and introducing steel fibers [4].
After 24 hours the OC specimens were demoulded, cleaned and cured for another two days in a water curing tank.
At the age of three days, the OC substrate specimens were taken out from the water tank for surface preparation.
Then the OC specimens were further cured in a water tank until the age of 28 days since the OC casting date.

Jacket structures are designed for a specific water level (LAT).
For studying effects of water level variation on structural behavior, the water level changed and each model studied separately.
In order to study the effect of design water level on structural elements responses after water level rise, four models with different design water level are made and Von-Mises stress are considered.
The effect of water depth variation on deck displacement As this figure shows, increasing the sea water level has considerable effects on deck displacement especially for structures with high operation water depth [19].

Pore water pressure was measured by pressure sensor (full range 2Mpa) capable of accurately recording pressure changes as low as 2kPa.
Pipelines There were two sets of lines (in and out) for passing gas and de-aired water respectively.
A small vacuum pump was adopted for the preparation of specimen and de-aired water.
After passing CO2 and de-aired water through for half an hour, respectively, the specimen was then consolidated for an hour.

They are very good in elasticity, water-biding, and endurance.
Watercolors broadly refer to all kinds of water-based colors.
They are made of water and Acacia gum mixed with anti-dry and anti-mold materials.
Pastels are refined from water-dissolved colors with some Acacia gum solution as binder.
There are oil-based markers and water-based ones.

Benefits of green building criteria and sub criteria for affordable home
The potential environmental benefits are improvement and protection of biodiversity and ecosystems; improved air and water quality; reduced waste stream and conservation and restoration of natural resources.
Regional benefits include support for solid waste management and improved water quality.
From previous studies done by [3] and [4], green affordable home need 50 % less energy to operate and can cut down waste since it uses 50% less amount of water compared to conventional homes.
A study done by [10] also revealed that implementing rainwater harvesting can save up to 34% of public water supply annually with unit cost RM 1.26 per m³ for a double storey terrace house in Kuala Lumpur and Selangor.
It will based on expert panel's opinion from housing industry professional and green building practitioners in Malaysia.
