人类眼睛的分辨率一般小于0.1mm,光学显微镜的分辨率为200nm,而电子显微镜则可以达到0.1nm。因此,可以说,借助于电子显微镜人类观察微观世界的能力放大了百万倍以上。无论是纳米材料的研
Human eye resolution is generally less than 0.1mm, optical microscopy resolution of 200nm, and electron microscopy can reach 0.1nm. Therefore, it can be said that the human ability to observe the microscopic world by means of an electron microscope has magnified more than a million times. Whether nano-materials research
