Laser cutting is a thermal process which is used contactless to separate materials.
During laser beam machining, the resultant thermal effect depends on the concentration of the beam and the physical properties of materials.

Mercury of cement plants comes mainly from coal and raw materials.
Depending on the different size and raw materials, of the plants, and mercury emissions under different conditions is not the same, so there is no mature mercury removal technology can be applied directly.1 Overview Mercury is a toxic heavy metal and non-essential element for the organism.
After dust removal the concentration of Hg in flue gas is different ,due to different Hg content of raw materials.
The more higher Hg content raw materials contain, the more higher the Hg concentrations are in flue gas.

Likewise, another way to enhance power factor(PF) is searching materials with a desirable band structure with small band effective mass and high valley degeneracy.
Recent theoretical work and experimental work suggest that the dimension reducing of materials could significantly improves the TE performance.

During the shear strength analysis, the failure criterion and materials stiffness degradation rules fitting for the analysis of X-cor sandwich’s failure mechanism were proposed and the X-cor sandwich’s failure process and modes were also clarified.
Strength Criteria and Materials Stiffness Degradation Rules.
Table 1 Materials stiffness degradation rules Failure type Materials stiffness degradation rules Z-pin shear off failure ，，，，， Z-pin buckling failure Resin region failure The final failure criterion is that as the strain increases the stress begins to decrease, the X-cor sandwich can be considered to totally fail and the analysis is stopped.

Experimental results Contour of ablation The failure mechanisms of materials under the shock of laser are ablation and vaporization, depending on the power of laser.
The former only needs to break the local keys of materials and requires lower power, and the later has to break the molecule keys and requires higher power.
In general, the pressure of materials under laser shock is several TPa [5].
