采用小角中子散射法研究了含有等体积水、油和不同浓度表面活性剂的AOT（二-2-乙基磺基琥珀酸钠）/${\ mathm {D}}_{2}$O/十烷的单相微乳的结构。每个散射中子谱都有一个明显的相互作用峰。随着AOT体积分数从0.18增加到0.42，峰值位置向较大的$Q$移动，峰高减小。光谱与有序的液滴相一致，而不是双连续结构。
Small-angle neutron scattering is used to investigate the structure of single-phase AOT (sodium di-2-ethylsulfosuccinate)/${\mathrm{D}}_{2}$O/decane microemulsions containing equal volumes of water and oil and a variable concentration of surfactant. Each scattered-neutron spectrum exhibits a pronounced interaction peak. As the volume fraction of AOT is increased from 0.18 to 0.42, the peak position shifts to larger values of $Q$, and the peak height diminishes. The spectra are consistent with an ordered droplet phase, as opposed to a bicontinuous structure.
