Materials Science and Engineering Materials outlook


Bound state, by the soliton and anti-soliton structure has been polaron structure, which includes the distribution of atomic structure and electronic band structure. In polyacetylene, the Ministry of the conduction band and valence band work, is a next, then becomes an anti-cis (B phase), its energy will be higher than trans-cis one. Thus the ground state is only one, other polymers such as poly-phenylene, with its ground state is nondegenerate in non-degenerate ground state polymer, can not generate solitons, polarons can only be produced, and can produce a variety of polaron, there is only a single charge ± with the polaron, there is also charged with two = Ze's polaron - bipolaron due to the presence of a constant attraction for non-degenerate ground state polymer. soliton and anti-soliton pair can not be separated into independent movement of the soliton and anti-soliton. soliton and anti-soliton will always in the bound state, this situation called annihilator ... 3 for polyacetylene, trans-ground state is degenerate, cis-non-degenerate, so the trans-polyacetylene in the soliton can have the independence movement. 2 Conclusion The new material is some improvement from the development of traditional materials up, some are constructed according to design come. some are from basic research and applied basic research results and gradually developed the new material of this source represents the three different levels. description of human knowledge and transform the world from the realm of necessity the ability to transition to the realm of freedom, that the universe is regular exercise, can know the new material is knowledge-intensive, technology-intensive, capital-intensive industries, a new class; many disciplines intersect, penetration, complementary most of them the result of organic chemistry, inorganic chemistry, quantum chemistry, analytical chemistry, solid state physics, solid mechanics, metallurgical science,p90x workout schedule, ceramic science, biology, emblem electronics, optoelectronics and other subjects of the latest achievements J: New material with other high-tech development is closely related to,love bracelet cartier, for example: the synthesis of new materials and manufacturing are often associated with many extreme conditions (high pressure, ultra-high temperature,ghd planchas, high vacuum, ultra-high catch, ultra-pure, micro-gravity, plate temperature, etc.) and technology linkages; new materials testing and evaluation of a wide variety of more sophisticated equipment needed: any new scientific and technological development in the traditional science and technology is always based on, in the traditional materials is based on the development of new materials and raw materials a base material an engineering material is closely related to the general circulation, where every aspect of improvement and innovation will lead to new materials produced in the 21st century is the century of life science technology, due to the knowledge economy and sustainable development. at all times The unity of science will gradually melt units. and even the dung of science natural sciences, humanities and social sciences will be unified financial units in the new century, materials science and engineering is bound to the rapid development of modern science and technology on the basis of large scientific uniform convergence trend toward high-function, ultra-high can win, complex and intelligent direction of the pilot materials and materials science has been an important material basis for social progress, human society is bound to the material make a significant contribution to the construction: References: [1] Shi Changxu new materials and materials science and technology status and development [M: Changsha: Hunan Science and Technology Press, 1984 [2 Introduction to Materials Science spine Zuyao .* [MJ .
