我们报告了隼鸟标本切割方法的调查。我们研究的目的是探索对单个粒子有效应用多种分析的可能性。我们研究了刀片切割锯、激光、聚焦离子束（FIB）和微压头物理断裂的切割性能。通过估计切割缝的长径比（即切割缝的深度比宽度）来检查切割性能。我们还调查了切割可能造成的污染和样品损坏。研究结果表明，在宽高比为10 ~ 20的情况下，可以将样品从<50 μm切割到500 μm，但会对样品造成一定的污染或损伤。我们的调查也为今后的样品返回任务所获得的样品的分析提供了重要的基础。
We report the investigation of cutting methods for Hayabusa samples. The purpose of our study is to explore the possibility of applying multiple analyses to a single particle effectively. We investigated the cutting performance of a blade dicing saw, laser, focused ion beam (FIB), and physical breaking by microindenter. Cutting performance was examined by estimating the aspect ratio of the cut slit, i.e., depth over width of the slit. We also investigated the possible contamination and sample damage by cutting. The result of the investigation shows that we can cut the samples from <50 μm to 500 μm using those methods with aspect ratios from 10 to 20, although they would introduce some contamination or damage to the samples. Our investigations also provide an important basis for the analysis of samples obtained by future sample return missions.
