After the pioneering work by Iijima in 1991 [7], recent developments in the field of carbon nanostructured materials, such as Carbon Nanofibers (CNF) and Nanotubes (CNT), have generated tremendous interest particularly towards their application as catalyst supports.
This will involve investigation of two key challenges: firstly, obtaining good attachment of CNF to the microchannel walls and, secondly, controlled growth of CNF inside microchannels.
The purity of Ni target material was 99.99%, and at least 99.95% for adhesion metals.

Therefore, it is instructive to carry out a research on key technologies of all-welded steel truss in respect of its application and promotion.
Welding distortion is a partial plastic deformation from internal stresses caused by non-uniform temperature fields on metal components in welding reach the material yield limit.
Regarding the significant influence of welding distortion on product quality and great importance from engineering field attached, there have been a lot of researches on the generation mechanism of welding distortions for an effective control to guarantee the product quality, while the repair of welding distortion could be avoided as much as possible.
The successful engineering projects indicated that the method was very effective for the prediction of welding distortions in large complex structures.
A professional engineering software (WSDP) developed for inherent stain and welding distortion analysis is introduced for calculations of complex structures.

Introduction The axially moving structures have received a great deal of attention due to their manifestation in a wide class of engineering fields.
The known exception is that Wickert [10] used a perturbation method to investigate the fundamental frequency of axially moving materials from a nonlinear integro-partial-differential equation of transverse vibration.
The principle of transform in engineering is to find a different representation of a signal under investigation.

The key of statistical pattern recognition is to identify patterns of the extraction of a statistical characteristic value, and then to make decision according to certain standards, so to identify the digital image.
