The attribute set has many kinds of reduction forms.
The intersection set of these reduction sets is called as the core of reduction.
The concept of the core can be understood from two aspects: firstly the core is the base of all reduction calculation because all reduction sets include it; secondly the core can not be reduced during the reducing calculation.
Input the data of standard pattern to knowledge base, after normalized, according to the property value, the evaluation process is divided into three degrees, namely as small, medium, large, which are represented as 0,1,2 respectively for convenience of calculation.
Here, the knowledge base finished reduction consists of R2,…, R5, R8,…, R10 7 attributes.

The results showed that stable silver nanoparticles collide solution with 20-30 nano, applied on oxidized cotton fabric under certain condition, could produce ideal antibacterial rate over 94% of bacterial reduction to both Staphylococcus aureus (S.aureus) and Escherichia coli (E.coli) after 50 consecutive washings.
The percentage reduction was determined as follows: Reduction in cfu (%) =×100% (1) A and B are the bacterial colonies of the original cotton fabrics and the finished cotton fabrics, respectively.
The antimicrobial activity of silver nanaoparticles finished fabrics was affected little by the increase of laundering circles, with more than 94% of bacterial reduction maintained even after 50 times of washing, which showed the bonds between cotton and HBP-NH2 I were durable enough after repeated launderings.

In contrast, the reduction of the series occurs in an irreversible one-electron reduction.
The data illustrate that there is quite an obvious electrochemical distinction between the compounds depending on the type of �-bridge, bridge length and the type of acceptor groups, (Table 2).

The content of SiO2 was more than 60% in the residue of pyrolusite detached manganese by reduction roasted and acid leached, and it was a better siliceous raw material because of less other impurities.
The experimental datas were well interpreted with a shrinking core model under chemical control.
The present study focused on pyrolusite slags from pyrolusite detached manganese by reduction roasted and acid leached processes.
The simplified equations of the shrinking core model when liquid film diffusion, ash/inert solid layer diffusion or the surface chemical reactions is the slowest step can be expressed as follows, respectively [11]: (2) (3) In order to obtain the kinetic parameters and rate controlling step, the experimental data was analyzed on the basis of Eqs. (2) and (3); and the experimental data validity was verified by statistical and graphical methods, the multiple regression coefficient obtained for the integral rate expression were calculated.
The results showed that the kinetic datas from the temperature studies were fitted to Eq. (3) and the correlation coefficients (R2) were greater than 0.96.

The main limitation in SiC growth modeling is the accurate knowledge of physical, thermal, radiative, chemical and electrical data for the different components of the reactor.
In addition, the link between the thermochemical history of the grown material and its structure and defects still needs further development and input of experimental data.
