The original material internal binding force is not enough to curb the rapid expansion of the high-density ion electron gas, and ultimately makes the material in the role of regions removed in the form of plasma eruption.
By using femtosecond laser to remove material, an unique processing characteristics is produced, such as no melt zone around the processing aperture, versatile to any materials, the processing region being smaller than the focusing size, and breaking the diffraction limit.
By using high power femtosecond lasers, building a special optical system, controlling procedures legitimately, the method can meet the needs of processing variety materials which is difficult to process.
The workpiece’s material is metal or alloy in this experiment.
The titanium alloy sample processing microwell array of 0.3mm diameter The workpiece is changed to nickel base superalloy materials in the same thickness for testing, then observed in the scanning electron microscope (100 times).

At the same time, the United States began large-scale carbon cycle science program.
Based on Xu Guoquan's research, the national per capita carbon emissions is respectively 0.667, 0.678, 0.74, 0.86, 0.98t during 2000 ~2004 [10], which is lower than those of Zhengzhou() .The reason is that Zhengzhou is the economic center of Henan province, where industrial development is very rapid and has obvious advantages in the textile, machinery, building materials, refractory materials, energy and raw material.

Thermodynamic analysis on destabilizing effect of zirconia products caused by aluminum is carried on by using material Gibbs free energy function, and then the experimental verification was tested by scanning electron microscope (SEM).
It leads to forming defects in materials, and then reducing the service life.
Experimental Verification Experimental Mixtures were prepared using stabilized zirconia with calcium oxide or magnesium oxide as stabilizer, aluminum powder as main starting materials and zirconia gel as a binder.
