Although PPS materials can meet the stress values, a long time and repeated concentrated stress will lead to fatigue fracture of the carrying frame structure.
And PPS materials can completely meet the forces at the condition of swaying with human support.
Although PPS materials can meet the conditions of the indicators in a short time, a long time and repeated effect will lead to fatigue fracture of the carrying frame structure.

Geogrid is paved 0.3m each layer, the stiffness is 500kN/m, length is 10.0m, and filling material is mixture of soil and rock.
FEM Model The paper use professional geotechnical code Plaxis for calculation, parameters of material are get from experiment report.
(3) If geogrid is properly used in retaining wall, the change of filling material’s weight density has little effect for horizontal earth pressure

The semi-solid material forming technology has advantages such as lower deformation resistance, good material mobility and so on [1].
The regression calculation and analysis of above equation were done by SPSS (Statistical Package for the Social Sciences).

A total 15 products with the differencial combination form 10 materials were sold The contents of net income and costs and sales were as follows: From 1997 to 2000 ( 1st ~ 4th ) π= -F= $20 at the first year (unit: $1,000,000) The growth rate of profit was 10% from 2nd to 4th year.
Because the lower net income and lower growth rate be found, so the innovative concept is introduced[28], 6 functional packs instead of 15products after 4 materials deleted and 2 tonicsgot from a contract with Cc company.

Forest lands are less affected by personal factor, with high coverage of plants, less nutrient loss, and they can acquire the nutrient supplement produced by the surface layer deadwood fallen leaf's humification ; In addition , the physical weathering of parent materials is shallow while chemical weathering deep.

Nowadays the application of RFID is very wide, such as identifying animal chip, refrigerating supply chain with the fresh products, producing medical vaccine, producing car alarms, controlling door access, managing logistics, rescuing the wounded, controlling parking place, making product line automation, and managing material.
At the same time, the reliability and precision are also greatly increased so that it can be applied in mine production safety monitoring system, and collect information for the materials sensitive to temperature in easily decayed food, medicines and logistics.

These kinds of silica structures contain more or less water and hence, they are more or less labile from the traditional viewpoint of materials science.
Choradin et al. have reviewed the use of sol-gel materials in medicinal science and they give many good examples on the encapsulation of proteins as well as DNA, cells, algae and bacteria in silica [18].
They discuss also organic modifications of silica and hybrids materials that further widen the possibilities to use silica-based materials in medical applications.
The same conclusion has often been made on the sol-gel derived materials, probably due to the more common use of the materials after different heat-treatments.
