| 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。

| Abstract: | 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. |
