The charge-flipping algorithm (CFA) is a member of the diverse family of dual-space iterative phasing algorithms. These algorithms use alternating modifications in direct and reciprocal space to find a solution to the phase problem. The current state-of-the-art CFA is reviewed and it is put in the context of related dual-space algorithms with relevance for crystallography. The CFA has found applications in many crystallographic problems. The principal applications in various fields are described with sections devoted to routine structure solution, the solution of complex structures from powder diffraction data, the solution of incommensurately modulated crystals and quasicrystals, macromolecular crystallography and single-particle imaging.
电荷翻转算法（CFA）是双空间迭代相位算法这一多样家族的成员。这些算法利用在正空间和倒易空间中的交替修改来寻找相位问题的解决方案。本文回顾了当前最先进的CFA，并将其置于与晶体学相关的双空间算法的背景下。CFA已在许多晶体学问题中得到应用。本文描述了其在各个领域的主要应用，各部分专门介绍了常规结构解析、从粉末衍射数据解析复杂结构、非等轴调制晶体和准晶体的解析、大分子晶体学以及单颗粒成像。
