Although the whole of human society has been not tremendous development but a good opportunity for development based on the advancement of science and technology, but it is still faced with a certain social risk and disaster.
Integrated the view of predecessors and objective practice, this article argues that "modernization is not , which is different from traditional society, a comprehensive and fast special social changes of social manner, the organization mode and social life way based on the wide application of science and technology but a social dynamic evolution process of traditional factors and modern factors exist fusion, and it generally includes material, system, spirit three levels".

In the solid state, the hard and soft segments tend to phase separation due to segmental incompatibility, this two phase structure give rise to the interesting and useful properties of these materials.
The PTMO and MDI are commerially raw materials used in polyurethane manufature.
Small-Angle X-ray Scattering The degree of phase separation (DPS) and degree of interfacial mixing for two-phase materials were measured by SAXS.

Figure 2 Stamping direction Drawing molding material circle design.
The face width of the material circle is bigger than the pull deep rough before forming material flange surface about 40 ~ 80mm, and taking into account of the installation location, size, etc.
The concave molding material surface, die fillet and die hole are provide by die.
