【摘要】 在自制X射线纤维衍射相机的基础上,对聚酯纤维进行两种照相几何安排.首先分离出完全无规取向的无定形态的散射贡献。然后,用合理的取向非晶态散射贡献的表征函数,对取向非晶态与晶相的衍射总贡献,进行计算机分峰拟合分离。由此获得具有全反射球统计性的取向非晶态含量。更多还原

【Abstract】 Two different geometrical patterns of PET fibre were obtained in the x-ray diffraction camera. The isotropic scatting noncrystalline region was first separated. The scattering of the oriented noncrystalline zone was characterized by a selected function. And its extent in terms of whole reflection sphere was then calculated after a multi-peak-resolution process in a microcomputer.更多还原
