Introduction Concrete is a kind of manufactured materials which is the most widely used [1].
At present, nano materials that researchers usually used to modify cementitious materials were nano-SiO2, nano-clay, nano-Al2O3, nano-Fe2O3 and nano-CaCO3.
When the content of NA was 2%, the machanical properties of modified cementitious materials were improved most.
So to different nanoparticle, it had the optimal content to modify the properties of cementitious materials.

Thus, looking for new food packaging sterilization materials has become the focus of packaging material research.
No secondary pollution is produced in the process, which can be ideal composite materials for food packaging sterilization.

The electricity materials play important roles in the study and some study will be put on it.
During the location process, engineering materials cost should be taken into consideration in order to get the cost minimum and efficiency maximum.
The transmission line materials cost of different voltage levels will be taken into account when selecting.
