通过对表面氧化的超细铁微粒的穆斯堡尔研究,确定了表面氧化层的德拜温度,改进了计算氧化层厚度的方法,得到了表面氧化层与核心α—Fe无反冲分数的比值随温度的变化关系.
Based on the Mössbauer study of superfine iron particles with surface oxidation, the Debye temperature of the surface oxide layer is determined and the method of calculating the thickness of the oxide layer is improved. The surface oxide layer and the non-recoil fraction of core α-Fe are obtained The ratio changes with temperature.
