氦离子显微镜能够提供所有扫描射线法中最高空间分辨率的表面图像，以及极高的表面灵敏度。
Helium ion microscopy (HIM) offers the highest spatial resolution surface imaging of any scanning beam method, as well as extremely high surface sensitivity.
我们已对所拍摄的光谱的谱线都进行了辨认，所有结果表明原子发射光谱分析法是研究不同条件下氦等离子体状态的一种十分有效的手段。
Spectral lines have been identified. All results indicate that the spectroscopic analysis of atom emission is an effective way to study the state of He plasma under different conditions.
因此，氦孔隙率可以作为低孔隙率胶凝材料的结构参数，而用压汞法可能会导致错误的结论。
Therefore, helium porosity may be used as a structural parameter for low-porosity cementitious materials, but an incorrect conclusion may be drawn if mercury porosity is used.
