Used the gauss body heat source to irradiate underwater aluminum target material, in this paper, simulated the process of punching, gauss body heat source equations as follows: (1) Where U is energy on the surface of the aluminum material; a is the optical depth of material; b is the absorptions of material for laser energy; r is 95% of the heat source center to spot radius.
Governing equation of the model can be expressed as a function of temperature: (2) Where is the density of material; is the heat capacity of materials; is time; is the heat source; is changing with temperature coefficient of thermal conductivity.

It belongs to the thermal theory of natural science.
According to some data, the value of materials commonly used in building is about 0.7W/(m*K).
The first is the use of long and short-foam construction materials.
Secondly, we can use hollow bricks and aerated concrete materials to reduce thermal conductivity.
