Many researches studied the influence of the slurries for the polishing of semiconductor and metal materials [1-5].
Also the pH value indicates the chemical property of the slurry, and different materials need polishing slurries with different pH value in the CMP process.

Most of the work is the simulation of materials which martensitic transformation is in the presence of welding process.
For example, for the first layer of weld, three different materials are set to simulated the phase transition processes.

The dried material was crushed, then we weighed 4 g of the homogenised crushed mixture into which we added 0.9 g of wax.
Due to this, the experiment could be realized with other contaminated material.

When the frequency of sound wave is 10kHz and the thickness of polyurethane is 2mm, the curve of the sound-transparent coefficient changing with different characteristic impedance materials is shown in Fig 3.
Fig. 2 The change curve of transparent Fig. 3 The curve of the sound-transparent polyurethane sound coefficient coefficient changing with different characteristic along with its thickness impedance materials in the second layer From the above diagram, it can be seen that the characteristic impedance of the second layer medium is different, the acoustic penetration coefficient will also be different, when the characteristic impedance is,that is, the characteristic impedance is equal or close to that of water, the sound-transparent coefficient will be the highest.
Material and geometry of the cilia, bonding mode between the cilia and central box, sheet resistance and the package materials have been optimized.
