| 图4 样品3的自扩散系数测定实验结果. (a)~(c)分别对应在2%、7%、10%梯度强度下的氢气扩散谱；(d)空隙内外两种氢分子信号强度ln(I/I0)随(gγδ)2(Δ-δ/3)的变化. 图中“in-pore”代表空隙内氢气分子信号强度，“ex-pore”代表空隙外氢气分子信号强度 |
| Fig. 4 The experimental results of the self-diffusion coefficient determination for Sample 3: (a)~(c) correspond to the diffusion spectra of hydrogen gas under diffusion gradient strengths of 2%, 7%, and 10%, respectively; (d) the relationship between the ln(I/I0) signal intensity of two types of hydrogen molecules (inside and outside the nano pores) and (gγδ)2(Δ-δ/3). The term 'in-pore' in the figure refers to the signal intensity of hydrogen molecules inside the pores, while 'ex-pore' refers to the signal intensity of hydrogen molecules outside the pores |
