Only relatively pristine material has the goods Landman is after, so his team USES a scanning electron microscope (below), which utilizes a beam of electrons to image surfaces, to find the best nacre.
只有相对原始状态的材料才拥有兰德曼所需要的研究对象，因此他的研究小组必须使用利用电子束表面成像的扫描电子显微镜(下图)去寻找最好的珍珠层。
Results EBCT had the advantage of high speed in scanning and high resolving power of time without mechanical abrasion due to the using of electron beam.
结果：电子束ct使用电子束的磁偏转代替球管机械运动，既加快扫描速度，又减少机械磨损，有很高的时间分辨率。
It is very effective to use the scanning electron beam (EB) heating to braze the stainless steel structural part with capillary-to-plate joints.
用电子束扫描加热的方法对具有毛细管板接头的不锈钢结构件进行钎焊是非常有效的。
