On the other hand, special microbial strains are added artificially into composting materials.
Okara was added to adjust C/N 30 for the final materials compost, and distilled water was sprayed on the raw material to adjust the water content to 60%.
The last, the controlling and monitoring system[7](Fig. 2) parameters were set as follows: the highest fermentation temperature was 68℃, moisture content of materials was 50-65%，oxygen content of materials was 10-17%.The system was in automatic control mode.

Fig.2 Structure of SDMS (3)Registration of public materials in rooms.
It is difficult to manage public materials in rooms exactly and make sure whether they are damaged.
This feature could record the situation about public materials’ destruction and help managers to punish the case that students break public goods purposely.

Some of the materials have much good comprehensive function, they are difficultly machined because of the material’s high strength, high hardness, or high toughness, high hardness strengthen item, which makes the small-hole cutting more difficulty.
The material of making twist drill is high speed steel & hard alloy, the main material is high speed steel.
Here the small-hole cutting is in the difficult cutting material, there is various non-metal materials, strengthen item nonferrous metal, various difficult cutting metal materials.
