The researchers analysed the sizes and structures of ash particles using a variety of techniques, such as atomic forcemicroscopy, scanning electron microscopy and X-ray diffraction.
研究人员使用不同的技术研究了火山灰颗粒的尺寸和结构，例如原子力显微镜、电子扫描显微镜和X射线衍射。

Atomic forcemicroscopy generates very high-resolution images (about 5-nanometer resolution) by “feeling” the surface of a sample with a tiny probe tip.
原子力显微镜是运用一种微小的探针去“感受”样本表面，能得到高分辨率的影像（约5纳米的分辨率）。

IBM physicists built the first microscope based on that approach, dubbed magnetic resonance forcemicroscopy (MRFM), in 1993.
