In the EDS equipped. SEM, the intensity ratio I(L) / I(K) of pure bulk samples Mn, Co, Ni and Cu has been measured with the ultra-thin window (UTW), and that of pure bulk samples Ni, Cu, Zn and Ge has been also measured with the Be window.

• 在扫描电子显微镜中用超薄窗(UTW)和铍窗的X光能谱仪分别测定了Mn、Co、Ni、Cu和Ni、Cu、Zn、Ge等四种纯元素厚试样的强度比I(L)/I(K)。
