用小角度X射线衍射方法测定了层状液晶各种组分变化的层间距离；
The interlayer space of lamellar liquid crystal was deter-mined by small angle X-ray diffraction.
代位元素在铁素体中的固溶，导致了铁素体晶格的畸变，进而引起了衍射峰向小角度方向漂移。
The high concentration of substitutional elements in ferrite results in distorting lattice of ferrite and thus the diffraction peaks of ferrite deviate to little Angle.
结果发现，经直接混炼之后，有机蒙脱土的衍射峰向小角度偏移很小，层间距没有明显变化；
However, the diffraction peak of the original montmorillonite significantly shifts to small angle, the layer distance increases more than three times.
