An empirical formula, r~x~-~y=0.618λ/sinθ, has been applied to carry out qualitatively structural analysis of the diffraction curve, and another r~x~-~y=7. 766/s to calculate the interatomic distance of some strong peaks from the reduced intensity curve.

用经验公式r~x~-~y=0.618λ/sinθ进行溶液衍射曲线I-θ定性结构的分析，而用另一经验公式r~x~-~y=7.766/s计算加权结构函数曲线s·i-s上某些强峰的原子间距。

Crystalline β-BBO thin films were successfully prepared on (001)-oriented Sr 2+-doped α-BBO substrates by using liquid phase epitaxy, pulsed laser deposition and vapor transport equilibration techniques. The films were characterized by X-ray diffraction and X-ray rocking curve. The present results manifest that the β-BBO thin films grown on Sr 2+-doped α-BBO substrates have larger degree of orientation f value and smaller X-ray rocking curve FWHM than the ones grown on other reported substrates.

Binding states between modified flax fabrics and anion dyes have been investigated by infrared spectrometry, X-diffraction, peeling of color and experiments on water proofing of modified flax fabric with taking reactive red X-3B, direct Chinese red 6B and acid yellow G for examples. The results show that binding force between modified flax and acid dye is coulomb's force, and besides hydrogen bond and gravitation among molecule, electrovalent bond has been formed among direct dye and modified flax.
