本文介绍了一种用透射电子显微镜检查金属试样表面的技术。通过电解抛光从一侧减薄原始样本;因此，在其中一个表面上保留了表面轮廓，例如滑动台阶。结果表明，位错揭示与表面滑移线;台阶高度和表面ontours，如那些疲劳条纹观察在高放大倍数由于锥截面效应。
Abstract A technique is described whereby the surface of metal specimens can be examined by transmission electron microscopy. The original specimens are thinned by electropolishing from one side; thus the surfaoe contours, e.g. slip steps, are preserved on one of the surfaces. It is shown that dislocations are revealed associated with the surface slip lines; the step heights and surface oontours such as those of fatigue striations are observed at a high magnification due to a taper section effect.
