X-ray scattering studies were performed to understand the structure and correlations in the lamellar phases of thick, freely suspeded films of (i) the hydrated phospholipid dimyristoylphosphotidylcholine (DMPC) and (ii) the ternar system consisting of the surfactant sodium dodecyl sulfate (SDS), cosurfactant (pentanol), and water. The films were drawn in a temperature- and humidity-controlled environment, where the layers were oriented to within 0.1 degrees . In the DMPC system, this made it possible to directly observe the orientation of the P(beta') modulation and to identify phase L(beta') as three distinct phases distinguished by the direction of chain tilt with respect to the lattice. In the L(alpha) phase of the ternary system, power law behavior of the (0,0,L) structure factor arising from the algebraic decay of layer correlatios was observed in single crystals.
X 射线散射研究用于理解厚的、自由悬挂的（i）水合磷脂二肉豆蔻酰磷脂酰胆碱（DMPC）和（ii）由表面活性剂十二烷基硫酸钠（SDS）、助表面活性剂（戊醇）和水组成的三元体系的层状相中的结构和相关性。在温度和湿度受控的环境中绘制薄膜，其中层在 0.1 度以内取向。在 DMPC 体系中，这使得可以直接观察 P(beta')调制的取向，并将 L(beta')相识别为三个不同的相，它们通过相对于晶格的链倾斜方向来区分。在三元体系的 L(alpha)相中，在单晶中观察到（0,0,L）结构因子的幂律行为，这是由层相关的代数衰减引起的。
