我们已经确定了位置相关函数对准堆栈的完全水合磷脂双层从非镜面X射线反射率测量的热漫散射。虽然公平的协议，可以得到实验和线性近晶理论在120 A以上的长度尺度，在小r，这是暂时归因于集体突起模式发生显着的偏差。
We have determined the positional correlation functions in aligned stacks of fully hydrated phospholipid bilayers from the thermal diffuse scattering measured by nonspecular x-ray reflectivity. While fair agreement can be obtained between experiment and linear smectic theory at length scales above 120 A, significant deviations occur at small r, which are tentatively attributed to collective protrusion modes.
