一.前言 电子显微镜(简称电镜)问世已近50年,在40多年前就被用来研究某些矿物学问题。但是,由于绝大多数矿物样品制备的困难及早期电镜性能等方面的问题,使其在矿物学上的应用一直停滞不前。直到70年代,由于高分辨率和超高压透射电镜的出现,并与选区电子衍射、X射线能量分析等多种测试手段相联合,同时也出现了离子束减薄制样装置,才使电镜在矿物学研究方面得到迅速发展,人们长期以来梦寐以求想直接观察矿物晶体构造的渴望终于实现了。在过去十多年中,通过使用现代电镜对矿物单位晶胞大小的结
I. Introduction Electron microscopy (referred to as electron microscopy) came out nearly 50 years, more than 40 years ago was used to study some mineralogy issues. However, its application in mineralogy has been stagnant due to the difficulties of preparation of most mineral samples and the problems of early electron microscopy. Until the 1970s, due to the emergence of high-resolution and UHV transmission electron microscopy, combined with various testing methods such as selective electron diffraction and X-ray energy analysis, an ion beam thinning sample preparation device was also introduced to make SEM The rapid development of mineralogy has led to the long-awaited realization that the desire to directly observe the mineral crystal structure has finally been realized. For more than a decade, the unit cell size has been knotted by using modern electron microscopy on mineral units
