本文提出了一种基于取样定理的磷脂体系X射线衍射分析中相的确定方法。通过改变烃链的长度来改变脂质层的厚度，以便从散射振幅重建连续变换。通过采用这种方法，相准确地确定在9个磷脂/醇系统的结构分析在交叉凝胶相。这9个体系分别是二肉豆蔻酰磷脂酰胆碱（DMPC）/丙醇、DPPC/甲醇、DPPC/乙醇、DPPC/丙醇、DPPC/丁醇、二硬脂酰磷脂酰胆碱（DSPC）/甲醇、DSPC/乙醇、DSPC/丙醇和DSPC丁醇体系。(C)2000爱思唯尔科学爱尔兰有限公司保留所有权利。
A new method based on a sampling theorem is proposed for determining the phase in the X-ray diffraction analysis of the structure of phospholipid systems. The thickness of a lipid layer is changed by changing the length of hydrocarbon chains in order to rebuild the continuous transform from the scattering amplitudes. By employing this method, the phases were accurately determined in a structure analysis of nine phospholipid/alcohol systems at the interdigitated gel phase. The nine systems are dimyristoylphosphatidylcholine(DMPC)/propanol, DPPC/methanol, DPPC/ethanol, DPPC/propanol, DPPC/butanol, distearoylphosphatidylcholine(DSPC)/methanol DSPC/ethanol, DSPC/propanol and DSPC butanol systems.
