摘要
本文叙述了用θ—2θ型X射线衍射仪精确测定电解质溶液结构的新的实验技术,设计制作了具有恒温功能的超厚液体样品池,并建立了样品池窗口强度的校正方法。建立在Johansson和Yamaguchi工作基础上,发展了液体X射线衍射数据处理和结构参数精细化的计算机程序,获得了非常令人满意的实验结果。由θ-2θ型X射线衍射仪精确测定的径向分布函数与θ-θ型衍射自由表面散射比较,表明DRF分辩率有所提高。
A new method to determine the structure of aqueous electrolyte with θ- 2θ type powder diffractometer has been developed in the paper. The super-thick liquid sample cells with the isothermal function have been disigned and the correction procedures for the diffraction miensity of window on the cell proposed. A very satisfactory experimental result of molten salt of hexaquamanganese nitrate has been obtained. The comparision between the radial distribution function cruve with powder diffractometer and θ-θ liquid diffractometer by the free surface scattering show that the resolving power has improved to the extent.
