Currently the SFA is widely adopted in analyzing the national cycle of materials, urban material metabolism and nutrient metabolism analysis in a certain valley, and mostly in larger scale and less in smaller scale (i.e. in industrial park or ecological sensitive area, etc.), especially rare in a certain industry or manufacturer.
Arsenic and mercury, and the substance flows within industries such as chemical engineering and forestry; the other is bulk material flow analysis (bulk-MFA), which mainly studies the substance input and output of the national economy system[4], with its focus on the mixtures and bulk materials.

In addition, ANSYS/LS-DYNA finite element analysis software was used to simulate water-entry process of cushion materials with different densities.
The material models of steel and water are easy to be obtained, and the real data can be obtained only when the mechanical models of cushion materials are acquired.
The acceleration curve in Fig. 12 and the stress curve in Fig. 13 can be obtained by substituting the three densities polyurethane materials.
According to the effective stress curves of the head, the cushion effect of materials with three densities can be seen.

Improved Method of Data Quality Assessment In reverse engineering, quality evaluation is an important part of detection, now there are two major questions to resolve: first, whether the product which is manufactured is uniform with the mathematical model or not; second, the error between the reconstruction model and material object is accepted or not, if it can not be accepted, edit the model or products and analysis the error, until satisfy the needs.
