用Barakat模型[Barakat(1987)]研究了具有累积角和平移无序的离散螺旋的X射线散射。Acta Cryst.A43，45-49]假设子单元之间的随机旋转和平移为高斯分布。该模型与第二类准晶模型相同。强度函数表明，随着贝塞尔级数的增加，强度最大值减小，而沿纤维方向的峰值宽度和强度最小值增大。
X-ray scattering from a discrete helix possessing cumulative angular and translational disorders is studied by the Barakat model [Barakat (1987). Acta Cryst. A43, 45–49] assuming Gaussian distributions for random rotations and translations between subunits. This model is found to be identical to the paracrystalline model of the second kind. The intensity function shows that the intensity maximum decreases with increase in the Bessel order, whereas the peak breadth in the fiber direction and the intensity minimum increase.
