大分子晶体的X射线衍射数据集的统计描述符可以使用初始衍射图像中存在的信息来建模。给出了晶体质量、光束孔径、振荡宽度、分辨极限、冗余度与数据统计量之间的定量关系。根据BEST方案中的模型，对这些方案进行了辐射剂量要求方面的分析。讨论了辐射损伤对数据统计的影响。
Statistical descriptors of the X-ray diffraction data set for a macromolecular crystal can be modelled using the information present in the initial diffraction images. Quantitative relationships between the crystal quality, beam apertures, oscillation width, resolution limit, redundancy and the data statistics are presented. They are analysed in terms of the radiation-dose requirements based on modelling in program the BEST. The influence of radiation damage on the data statistics is discussed.
