样品切片制备及电镜观察技巧

Sample preparation of ultrathin section and its microscopic observation skills

超薄切片技术是材料研究中电镜样品制备的关键环节,将样品制成超薄片或直接对样品断面切割,使得样品能够在电镜观察中得到清晰而真实的图像。然而超薄切片制作和电镜观察过程中,常常会出现异常的实验结果,观察不到样品所需要的最佳信息。本文结合实例就切片及电镜观察技巧方面进行简单探讨。

Ultrathin section technique is a key step in preparation of microscope samples for investiga- tion of materials. In this paper, ultrathin section technique and electron microscopic observation skills were discussed by combining concrete examples.
