The Influence Analyses of the Intangible Factors in Urban Real Estate Appraisal;

What is worthy of serious attention is disorderly elements in institutional transformation and the negative impact of "policy inertia" of the original system.

To the material factors as the main driving force for research clusters upgrading is mainly based on immaterial factors embedded in the material factors, so that the critical point of the marginal revenue dimin- ishing which it is decided by the itself resources characteristic passes backward.

With the development of society and economy,the relative proportion of material factors is descending and immaterial factors increasing,which are made up of the whole basic factors.

Based on the summary of the traditional research on increasing returns,the paper point out that the changing direction of returns is determined by the relative proportion of material factors and immaterial factors,which are made up of the whole basic factors.

Effect of shape factor on heat pot transformation of casting;

Based on the reduced scale ring rolling and finite element simulation,materials axial transferring pattern was studied and a formability evaluation method was proposed including the shape factor.

Based on the fact that particles are non spherical,the author focuses on the studying of the effect of shape factor of particles on the viscosity of slurry according to Simha s equation.
