| 摘 要： | 本文讨论了测量Kubler指数时产生的误差来源;提出以统计学方法描述“Strip型”衍射峰的半高宽度及其误差大小;以衍射强度、衍射峰形态与测量条件关系式描述“Digital型”衍射峰半高宽的测量误差大小。并特别提出了数字化衍射仪平滑操作产生的误差原理和总体趋势。提出的原理及公式,不仅适合半高宽的误差计算,也适合于其他衍射参数的分析计算,并可用于数字化光谱分析计算中。

| Abstract: | The error sources were analyzed from the measurement of the Kubler Index. A statistical method was proposed for the error calculation of full width at half maximum (FWHM) of X-ray diffraction peaks from the "Strip-chart" diffractometer, while formulas describing the relations a-mong the intensity, shape and measuring conditions were used for that of "Digital" diffraction peaks. A special discussion is given for the data smoothing-an operation could be used for "Digital" peaks--in which the principle of error production and general trend of smooth operationare described. It is believed that these equations and principles could be also used for the calculations of any other peak parameters and digital spectrum analyses. |
