Nanometer materials and their application technology as an important part of nano science and technology, is considered to has a decisive role to the development of contemporary science and technology.
In order to promote the development of nano science and technology, in July 1990 in the United States in Baltimore held the first international conference of nanotechnology, and announced that "nanotechnology" the international journal.
Nanometer materials.
Countries engaged in materials science experts and scholars are desire to develop new nano materials (especially the nano composite material), seeking for new technology of the preparation of new nano materials, to further explore the particle size of nanometer material, the amount of phase interface, the interface phase relationship between atomic structure and nanometer material performance, and the diffusion process of nanometer materials, the formation mechanism of nanocrystalline ceramics (especially the reticular formation) for further research.

The database collected corresponding materials on public sports from nearly 60 countries, with up to 2 million characters in volume.
With the document literature method, we have retrieved academic journals published between 1998 and 2010 on sports and material databaseinformation from Chinese Journal Full-text Database, and have also consulted related works in information science and material databasedesign.

Finally, the experiment results show that this proposed method can exactly identify the faults of composite materials.
Finally, the experiment results show that this method can exactly identify the faults of composite materials.
It has very great applied foreground to use ANN for damage identification of composite materials.
In this paper, it was studied to use improved BPNN for damage identification of composite materials.

Building Materials Composition Influence to Sound Transmission Loss (STL) Reduction Erni Setyowati1,a, Anggana Fitri Sadwikasari2,b 1Building Science Laboratory, Engineering Faculty, UNDIP, Semarang, Indonesia 2Islamic University of Indonesia (UII), Yogyakarta, Indonesia aernisyahdu@gmail.com, banggana@gmail.com Keywords: Airport noise, building material composition, STL reduction.
The development of the airport always causes the noise impact to the surrounding environment.1 Housing close to the airport will be annoyed by the aircraft noise, especially if the building is not added by absorber building materials.
The decrease of the noise level found out from the research is caused by the value of Sound Transmission Loss (STL) of the building materials composition.
In some journals that I wrote that the building models are not assumed to be a single model.

The materials transportation system with storage bin is widely used in mines, power plants, material yards, and etc.
Introduction In some materials transportation system, storage bins are often set.
The block diagrams of the materials transportation system with storage bin.
(1)When links ahead of bin 1 are in failure, links behind bin 2 can continue transporting materials of bin, The maximum value of materials of bin is designed bin capacity Q tons.
