This appearance is because of the variations in the effective thickness of the component along the orientation of the X-ray penetration exceed the limit of the dynamic range of the X-ray imaging system. Complete structural information cannot be obtained, and this lack will impact the quality of the X-ray image. To solve this problem, the technology of X-ray multi-spectrum imaging based on variable voltage has been advanced. In this new method, the tube voltage is adjusted several times to accommodate the full necessary range of effective thickness, and then, the extracted images are fused to reconstruct the full projection information. Experiment shows: for the 12 bit imaging system, the effective dynamic range has expanded 4 times. So the new technology can adequately enlarge the hardware potential to completely represent the internal structure information of a complicated structural component.

Application of acoustic emission technique to detect copper pressure equipment may be one of effective methods. This paper produced H62 copper tensile specimens, which stretching process was monitored by acoustic emission technique. The results show that, the copper has a shorter elastic stage; less high-amplitude signals were brought out when tensile specimen was broken because of its high viscoelastic characteristics; the effective number of acoustic emission signals related with the loading rate with the same copper specimen. And there were more effective acoustic emission signals with a faster loading rate; copper material waveform peak of acoustic emission signals appeared in the range of 210-340 kHz. Conclusions can be referred when acoustic emission monitoring was carried out for copper pressure equipments.

Hangzhou Special Equipment Inspection Institute, Zhejiang, Hangzhou, 310003, China; 2. Institute of ProcessEquipment, Zhejiang University, Hangzhou 310027, China) Abstract: Tensile process of carbon fiber composite laminate was monitored by acoustic emission technique (AE). And the acoustic emission signals by tensile specimens of different winding angles were analyzed. The results show that carbon fiber released signals of different characteristics in different stages. So, the acoustic emission technique can effectively distinguish the different stages such as delaminating, detaching and fracture. Also, different angles in specimen’s layers of carbon fiber had different mechanical properties and failure mechanisms. Analysis on experimental data showed that acoustic emission testing technique can determine the process of different internal activities in carbon fiber composite laminate. Therefore, it can be used in the integrity evaluation for carbon fiber composite materials.
