航空学

On the hopeful 21st century, the rapid development of information, biotechnology, energy resources, environment, advanced manufacturing technology and national defense have produced the new demand for materials. More and more small size of materials will meet the demand of miniatured, intelligent, highly integrated, densely memorized and super fast transmission element. Aerospace industry, up-to-date military equipment, advanced manufactured technology and so on has required better and better properties.
