近年来以复合材料、超导材料为首的新材料的开发十分活跃 ,微型致动器和微型传感器等微型机械的实用化以及在电子领域小型高功能化和环境问题都日益受到重视 ,还有医疗界各个领域中都对于微小材料和微型制品的应用日益关注。但是对于这些微小材料的实用化至关重要的 ,便是对其? In recent years, the development of new materials such as composite materials and superconducting materials has been very active. The practical application of miniature machines such as micro-actuators and micro-sensors, as well as the miniaturized high-functionalization and environmental issues in the field of electronics are increasingly being emphasized. Increasing attention is being paid to the use of tiny materials and micro-products in all fields of the industry. But for the practical use of these tiny materials is crucial, is it?
