Onundi et al. [6] reported that certain solid materials possess a high affinity for heavy metals, this enables the removal of such metals from a solution by attachment to the solid surface with high efficiency.
A number of low cost adsorbents have been tried from industrial and agricultural waste to find alternative materials to the commercial activated carbon for dye removal.

Biochar is cheap and more sustainable as it does not require chemical reagents and can be made from waste materials [5].
Based on Yu et al. the biochar made at 850°C rather than 450°C showed greater affinity for sorption of organic materials because of its higher surface area and nano-porosity [7].
Biochars produced in high temperature would have high surface area and large pore size that are applicable for sorption of substances including heavy metals and organic materials.

The experiments researched damage of cement based materials in the erosion solution.
Those materials reacted with Ca (OH) 2 and produced gelling substance.
So the materials which were easy to be eroded was reduced greatly.

Micro slits fabricated on the surface of tungsten carbide mold material with outline dimensions from 0.3mm to 2.1mm, the width and depth of 1 mm.
Owing to the glass materials has more advantages, e.g., thermal stability at high temperature, high chemical stability, high refractive index, wide range of spectrum.
In addition, the FK5 glass material, which was developed by SCHOTT to apply on PGM process [8-9], was used.

Traditional Chinese headdress is an important part of the traditional Chinese culture, which provides rich material for computer animation.
The process of traditional Chinese headdress creation includes collection, modeling and assigning new material, which is complex working and time-consuming.

When the box parts drawing, the materials of the radius region flow to the straight edge portion, the straight edge portion tangential shrinkage in the flange area( εθ < 0 ), so that the strain strength of straight edge portion increases , and the degree of hardening of the material increases[4].
The closer to the straight edge central, the less materials of rounded area flow, therefore, the smaller hardening degree of the material.
