当宇宙飞船载着人类对宇宙的疑问飞向太阳系边缘、探索宏观世界时,人类并未减弱探索微观世界的兴趣。科学家和工程师们正在向无穷小的微型王国发起新的进军。不远的将来,我们将能从电影上看到微型“潜水艇”进入人的血管去摧毁或溶解血栓。微型技术将在医疗实践中一次又一次得到成功的应用。这是一个极小极小的世界,科学家和工程师们只能用毫微米才能测量自己的一件件得意之作。他们 As spacecraft carry human questions about the universe toward the fringe of the solar system and explore the macrocosm, humankind has not diminished its interest in exploring the microcosm. Scientists and engineers are launching new marches into infinitesimal miniature kingdoms. In the near future, we will be able to see miniature “submarines” entering the human bloodstream from the movies to destroy or dissolve blood clots. Micro-technology will be successfully applied again and again in medical practice. It is a tiny, very small world where scientists and engineers can only measure their own piece of art with nanometers. they
