Evaluation of the Effect of Chemical Treatment on the Mechanical Properties.

      Аннотация: Cellular telephones, computers, medical lasers, disease-resistant crops, satellites, biotechnology, optical fiber networks—all these 20th-century technologies and many others can trace their origins at least in part to science and engineering research. New knowledge alone is not enough to achieve major economic, military, or social objectives. But through the combined efforts of business, government, and academic and other nonprofit organizations, new knowledge has been converted into new technologies, new means of production,and new industries. In the process, science and engineering research has enhanced national security, improved human health, produced a stronger economy, and led to a cleaner environment. Science and engineering research will be even more influential in the 21st century than it has been in the 20th century. No one can predict which technologies will define the next century. But we know that the increasing interconnection of computers into a global network will transform work, communications, entertainment, and education. Greater understanding of biological processes will help to meet the needs of an expanding global population while reducing the adverse effect.
