The grinding wheel manufacturer specifies the characteristic values (bounding type, grain size, grain material, hardness, etc.) which are only general information and do not represent the actual state of the grinding wheel during the process.
Acoustic Emission on Grinding When a material is deformed by some kind of external stimulus, as occurs on grinding operations (contact and friction between grits and workpiece) the lattice structure of the material is distorted and rearranged.

The reason may be that the research on the mechanical properties of laminated glass with PVB film has not been conducted in domestic yet, which result in lacking of experimental data to support the material parameters, inaccurate understanding of the mechanical model of the laminated glass and corresponding numerical simulation, The shear resisting is a main factor affected the performance of PVB film, and there hasn’t experimental research on the shear modulus in China yet.

As the nonlinear efficiency is defined as γ = 2πn2/λAeff, where n2 is the nonlinear refractive index, λ is the operating wavelength and Aeff is the effective mode area, the nonlinearity of PCF can be optimized via the nonlinear refractive index, n2 of the material and the effective mode area, Aeff, which is determined by the fiber structure[2,3,4].
A nonlinear ratio of ~11,000 W−1km−1 has been proposed by utilizing high nonlinear liquid CS2 slot-structure core and high nonlinear bismuth background material [6].

Barra et al [9] reported the influence of the porous material on flame stabilization by numerical method.
They concluded that the material properties of porous media significantly affect the stable operating range.
All the arguments mentioned above were mainly foucsing on the influences of the equivalent ratio, velocities, matrix material on flame shape, location, and stablization.
