Introduction Acoustic emission technique detected and analyzed the emission signal materials produced in a mechanical process by means of the sound, so as to obtain the changes of the internal structure of materials information.
Therefore, how to establish between acoustic emissions signals with material mechanics process connection is one of the important research content of the acoustic emission technique.
Acoustic emission signal is after deformation and cracking of the material after processing the information, but can still reflect the variation of the internal structure of materials.

In order to full use of BayanObo resources, a process named continuous extracting niobium from hot metal was proposed by University of Science and Technology Beijing and Institute of Metallic Materials of Japan.
Experimental Materials In the experiment, associated iron and niobium ore was chosen as the niobium-bearing material, and its chemical compositions listed in Table 1.
The reduction process can be described based on porous material reaction model.

Efficient luminescent materials used at lower voltage and higher current density for FEDs are becoming more important for real and potential applications.
Spray pyrolysis process [2,3] is an efficient technique to prepare nano-scaled phosphors [4] due to good mixing of starting materials, small limited space and relatively low reaction temperature.
