In the years passed since the first conference held in 1999 [1] the subject has expanded from isolated pioneering publications to one of the most actively developing trends in materials science and related disciplines such as materials processing technology, solid state physics and chemistry.
Recently the scope of NanoSPD was broadened to include further engineering and medical branches, thus increasing the number of publications in this field to several hundred per year and boasting top-cited papers in leading materials science journals [2].
As a resume of the scientific outcome of the conference, it was stated that bulk nanostructured materials produced by SPD have become an extensively pursued area of research in materials science.
In particular, the International Symposium on Ultrafine-Grained Materials moved its sessions on all aspects of science and technology of bulk ultrafine-grained materials produced by SPD techniques and other techniques.

This paper illustrated the Safety levels in the Chinese Construction Materials Industry (CMMI) during the Twelfth Five-Year Plan.
Introduction CCMI is one of the most important basic raw materials industries in China and plays an important role in the national economy.
Half of the world totals of these materials are produced by or consumed in China(Nesadurai,2005).
Moreover, the quantity and quality of Chinese new wall materials, glass fiber products, glass deep processing products, FRP products, and cement products has also improved significantly.

At present, cermet materials are focused on more and more [2-5].

The problem following is that process brings too much unrecycle talc paper plate leftover materials when the talc paper plate is cut out and molding.
Those leftover materials always be abandoned as crab.
Different concentrations of immersion materials indicate the same variation rule.
Influence of immersion concentration Figure2 indicates that decomposition rate increases as concentration of immersion materials increases, but the variation amplitude is less.
