These parameters are of poor scaling for polymer material.
For example, the Generic PP material, its 7parameters are 0.2751, 24200, 4.66e+12, 263.15,0, 26.12, 51.6.
Test case Table 1 shows a part of test data of polymer material PPF401 using Capillary Rheometer.

In the discrete element method (DEM) model, the value of friction is determined according to the material of particle or wall, and the rough degree and coefficient of sliding friction, generally takes it from 0 to 1, and the value of the coefficient of rolling friction is smaller. 3 Numerical simulation Particles flow and mixed because of the common function of gravity and axial rotational motion in equipment, but for the complexity of particle flow, particle flow and hybrid mechanism researched is less, so far only a few scholars abroad devote to the hybrid mechanism.
For cone mixer is concerned, hybrid materials in mixer are mainly affected by particle properties, density, size and shape, capacity of mixer and mixer speed and the influence of operating conditions.

Introduction Large interest for solar cells, fuel cells, gaz detectors, catalysis, inter-layers dielectrics among others, led to the emergence of porous thin films as one of the leading players in modern material science.
The common tools, such as BET, being more adapted to the powders or bulky materials, a new way appeared several years ago to characterize more specifically the porous thin films : The Ellipsometric Porosimetry (EP).
The main interests for this material come from its morphological properties such as its photoinduced electronic transfer or also its high chemical stability.
In addition, Ellipsometry allows the absolute characterisation of optical properties of materials by extraction of the N and K data.

In view of the characteristics of roofwater pollutants, the media, particular size, thickness and rate of filter material were determined by laboratory tests.
It shows that roofwater was polluted slightly compared with urban stormwater, but the initial volume has a high concentration of main pollutants, such as turbidity and chromaticity [2]; in addition, the roofwater quality related to rainfall intensity and other factors, such as roof material, air quality, and temperature and rainfall interval.

These solvent systems can offer a novel chemical environment because of their unique properties such as negligible vapor pressure, low melting points, wide range of liquid temperatures(up to 400˚C), low toxicity, non-flammability, large electrochemical window, good solvents for many organic and inorganic materials, high ionic conductively and thermal stability[2].
The blue shift of ZnO was caused by quantum size effect of nanometer material.
