一、引言透射电镜拍摄低倍照片有如下几个优点: 1.底片上包含了大面积的样品形貌信息,从一张照片上能看到各种组织形态的全貌,便于全面分析。 2.利用透射电镜分辨率高的特点,底片还可以作2至5倍、甚至更高倍率的光学放大,而所得的大幅面放大照片仍可不失其原来的细腻感。
I. INTRODUCTION TEM images taken at low magnification have the following advantages: 1. The film contains a large area of the sample topography information, from a photo you can see a variety of organizational forms of the whole picture for a comprehensive analysis. 2. The use of high-resolution transmission electron microscopy, the film can also be 2 to 5 times, or even higher magnification optical zoom, and the resulting large format photos can still be magnified without losing its original sense of delicacy.
