本人初学。在看一篇关于有无机杂化的论文，其中关于SAXS的图像实在是看不懂，求指点啊 - 图中横纵坐标分别代表什么？ - 图里的几个数值：33.2nm，36.2nm，2.94nm分别是什么意思呢？ 相关原文： The structural transitions of LC phases of hybrid L1/T1 were examined by small-angle X-ray scattering (SAXS) measurements.15 Figure 3 shows the SAXS profiles of hybrid L1/T1 and of a single component of L1. The scattering profiles of L1/T1 at 70, 90, and 110 °C (Figure 3a-c) suggested the existence of periodic particle interactions at an interval of 33.2 nm, corresponding to the total width of a T1 particle covered with LC molecules. Therefore, the mesomorphic phase seems to have a nematic-like one-dimensional order in the direction of the long axis of the acicular particles. Figure 3f shows a profile of the single component of L1 at 70 °C, in which the sharp peak at 2.94 nm corresponds to the thickness of a layer unit of the smectic multilayer structure. 本人翻译： L1／T1杂化的液晶相结构转变通过X射线小角散射测量法（SAXS）检测。15图3为L1／T1杂化和一个L1单组分的SAXS曲线。 L1／T1在70，90，和110°C的散射图像（图3a-c）说明了在33.2nm区间内周期性粒子相互作用的存在， 相应的T1粒子则覆盖了液晶分子的总宽度。因此，介晶相看上去在针状粒子长轴方向上有向列状的一维顺序。 图3f显示在70°C时单组分L1的轮廓，在2.94 nm处达到顶点，相应近晶型多层结构的一个层。 QQ截图20131119164813.jpg 返回小木虫查看更多
