Decomposition temperature’s marked increasing may result from substituent (-SO3H)’s existence making the material’s symmetry become better, which will make the material insensitive and stable.
SEM photograph Figure.4 showed the SEM photographs of raw material PP-g-St fiber and SACEF production.
The chemical structure of PP-based cationic exchange fiber has no difference with granular ion exchange resin but the fibrous appearance made it has special characteristics in property and plays a unique role where most traditional materials couldn’t work.

A typical analysis of steady state heat transfer includes four steps: Before modeling we should firstly define job file name, job title and the use of the unit system, after we enter the processing stage, the completed work includes: selection of unit type, setting unit options, setting real constant, materials thermal properties, geometric model, setting the grid cell size and generation of finite element analysis grid unit.
In the set of material properties, it is noteworthy that not only to give the elastic modulus and Poisson's ratio, but also gives the thermal conductivity.

For example, design modification, handling on-site visa as well as the rise of expenses for equipment, materials and manpower.
The objective control is conducted from the angle of the real estate development enterprises—the contractors and emphasizes the control of various costs and expenses in the construction process, including the control of construction period, design modification and on-site visa as well as the control of expenses for manpower, materials and machinery equipment and indirect cost.
According to the experience of the United States, in carrying out the policies for public house construction, one of the negative effects in large-scale concentrated construction is that it has intensified the polarization between the rich and the poor in urban residential space, concentration of poverty and social segregation, aggravated social instability, and made the US government have to re-consume large quantities of manpower and material and financial resources to carry out the policy of mixed settlement to alleviate poverty concentration.

Introduction Over the last couple of years, ecological awareness and other environmental issues have led to the development of composite materials based on renewable resources such as natural fibers as environmentally friendly and low-cost alternatives for synthetic fibers and the use of plastics based on renewable resources for the development of true biocomposites.
It is also necessary to study of flame sensitivity of these composite materials, which is desirable not only for the useful insights it can produce but also for its fire-safety importance.
Experimental 2.1 Materials Polypropylene (PP), the block copolymer of ethylene (grade: Stamylan P 412MN40 of DSM) as matrix and PP maleic acid anhydride grafted co-polymer (MAPP, Fusabond P MD-353D, Du Pont) as coupling agent were used.

Fig. 1 Three-dimensional model of the Chassis made in Pro-E wildfire Choosing materials and attribute.
Suitable material is fundamental to good design of this work, which relates with the demand meeting of tractor’s function, so the materials should be chosen appropriately while the frame structure of Chassis is well designed[5].
Load the Three-dimensional model of the Chassis into Ansys12.0, when materials and attribute chosen, grid division, and Chassis constraint are finished (refer to above paragraphs), load and proceed to finite element mechanics analysis.
