Introduction Silica aerogel is an attractive material in many fields, such as thermal insulation, adsorption, acoustic insulation etc. due to its high porosity (80~97%) and high specific surface area (500~1200m2/g) [1,2].
Commercial expandable polystyrene (EPS) is a traditional insulating material used in exterior insulation, food preservation, and so on for many years as its low thermal conductivity which benefits from the low density and a large number of micrometer/millimeter (μm/mm) closed/open pores[6,7].

The scalar represents the volume fraction of a distinct component (material) in a cell.
Coefficient of volume expansion is a constant for any particular type of material, used in calculating the amount by which the volume of that material will change as a result of temperature change.

There are many precious rare elements gases and compounds, which are indispensable materials of defense industry, atomic energy industry, chemical industry and agriculture industry.
Rare elements such as lithium, sodium, potassium, boron, iodine, bromine, and nuclear materials such as heavy water, hydrogen and oxygen isotopes are extracted and purified from geothermal water.
So it will have some good or bad effect on breeding and crops because of the chemical materials geothermal water contains.
Geothermal water is extracted from the well by a pump and provides heat to villas, Nangong Village Hotel, office and ordinary buildings, geothermal science exhibition center through radiator cycle.
