20世纪末期,人类认识自然的手段有极大的进步,其中在时间和空间的测知方面已达到飞秒级和原子级。扫描隧道显微术(STM)的发明(1986提获诺贝尔物理奖)使人们可以直观地观测原子,这无疑对研究物质的表面结构以及被吸附在表面上的任何分子、原子及原子、分子的排布状况前进了一大步,具有巨大的理论及实际意义
At the end of the twentieth century, mankind has made great progress in understanding nature. Femtosecond and atomic levels have been reached in the measurement of time and space. The invention of Scanning Tunneling Microscopy (STM) (1986 Nobel Prize for Physics) allows one to visualize atoms intuitively, which undoubtedly affects the surface structure of the material studied and any molecules, atoms and atoms, molecules, molecules The arrangement of the situation a big step forward, with great theoretical and practical significance
