综合分析狭缝系统对反射法定量测建极图的影响,提出了依靠合理选择衍射狭缝以减少散焦效应,提高测量精度和有效扫测范围的方法。据此,推荐了一组测定六方晶格钛材织构的衍射狭缝系统。 A comprehensive analysis of the influence of the slit system on the quantitatively measured polarographic map of the reflection method is proposed. The method of reducing the defocusing effect and improving the measuring accuracy and effective scanning range by means of choosing the diffraction slit rationally is proposed. Accordingly, a set of diffraction slit systems for determining the texture of a hexagonal lattice titanium has been proposed.
