世界毫微技术新发展目前，科学家已研制出大小不到－毫米的发动机。日本研究人员正在设计一种微型机器人，小到可在人的血管里穿行，以便把治病的药物准确地投放到人体内的正确部位。目前已研制成的汽车防撞气袋里含有许多微型加速计。这种加速计小到肉眼看不见的程度。美... New Developments in World Nanotechnology At present, scientists have developed engines of less than a millimeter in size. Japanese researchers are designing a miniature robot that travels through human blood vessels to precisely target therapies to the right parts of the body. Has developed a car anti-collision bag contains many miniature accelerometer. The accelerometer is so small that it can not be seen by the naked eye. nice...
