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。
