| 摘 要： | 采用θ-2θ型粉末衍射仪测定了液体汞的结构.提出了直接利用由X射线衍射分峰法所确定的衍射峰的位置和强度分析单原子液体结构的简单方法,并测得液态汞的最近邻原子间距R1为3.00 A,次近邻原子间距R2为3.38 A.研究结果表明X射线衍射分峰法对单原子液体体系的结构分析是有效的.

| Abstract: | The structure of liquid mercury is determined by 0 -20 type powder diffractometer. A new simple method is proposed to analy the structure of non-atom liquid by using the intensity diffraction profiles. It is found that the space between two nearest neighbor Hg atoms is 3.00 A and the second near neighbor atoms is 3.38 A. The method of peak separation for X-ray diffraction profile is proved to be effective by applying to non-atom liquid system. |
