电子显微镜(以下简称电镜)的种类包括透射电镜(TEM)、反射电镜和扫描电镜(SEM)三种形式。它与光学显微镜相比具有分辨能力高和放大倍数大的特点(表1),能直接观察材料的微观结构。我们曾用电镜对某些固体润滑剂的制备工艺、润滑性或抗摩性能与其微观结构间的关系进行研究,现简述如下。 Electron microscopy (hereinafter referred to as the types of electron microscope), including transmission electron microscopy (TEM), reflection electron microscopy and scanning electron microscopy (SEM) in three forms. Compared with the optical microscope, it has the advantages of high resolving power and large magnification (Table 1), and can directly observe the microstructure of the material. We have studied by electron microscopy the preparation of certain solid lubricants, lubricity or anti-friction properties and the relationship between the microstructure, are summarized below.
