The stress state of shearing area begins to change, and the equivalent stress is greater than that of the surrounding material.
With the deeper cutting of the disc cutter, the deformation and stress of material continues to increase.
The micro crack will appear near the blade edge of the cutter when the stress exceeds the ultimate strength of material.

Fig. 4 3D expression of railway and road (Multiage-Paradigm Company，2001) The methods mentioned above are similar, mainly by setting textures and materials on the road surface to achieve the road expression with diverse levels and building materials.
Railway has the highest level in all kinds of roads, which can be characterized in 3D environment by the rail that is similar to the real world or by superimposing railway pictures on the road surface, as well as by applicable materials after vector modeling.
Utilizing the approach stated above, the road level can be demonstrated by adopting different width, height, materials and textures.

Materials The test soil sample was took from the construction site of Linglongshan project developed by China State Construction International Co., Ltd, Tongzhou District,Beijing, China(39°54¢35²N, 116°34¢4²E).
The enzyme sample used in this study was provided by Shenzhen Terra Lutong Science and Technology Co., Ltd.
In general, the more dense material, its strength will be higher [5].

The doping could influence the electron transport in the photoelectrode materials and interface charge recombination between the photoelectrode materials and the redox electrolyte.
The study focus on the effect of metal dopant (Al, Fe, Ni and Zn) in TiO2 photoelectrode materials on the performance of the fabricated DSCs.
Table 2 summarized the concentration of desorbed dye solution per grams of photoelectrode materials films with respect to the various metal-doped TiO2.
Comparing the value of Rdc, TiO2 photoelecrode doped with Al exhibit lowest Rdc compared to other types of photoelectrode materials.
