Electrical measurements are one of the oldest techniques also used in materials science.
The positron annihilation technique is one of the nuclear methods used in material science.
The advantages of this method are in the obtaining of both qualitative and quantitative data on defect behavior in materials.
The main assumption of the simple trapping model is that positrons annihilate in solid materials from a free or trapped state.
This model assumes that the positron exists in one of only two states in the materials, the free or Bloch state and the defect trapped state.

At the same time, we have to consider thermal conductivity, strength, material cycle and safety of insulation materials synthetically.
Besides, these insulation materials all required the best price and good processing technology, etc.
Currently there were many common insulation materials used in rural wall, but these materials were not well in the rural area because of lots of reason，such as the price, the construction and the other .
For Flat roof design, many good materials were used to arrange between the waterproof layer and the sloping layer.
