本文介绍了用中子衍射法测定结构因子的方法。同位素替代的方法，它允许我们分离的偏相关函数，也被提出。合适的仪器，实验程序，和校正。其他不太传统的技术，如同构替代和异常色散也进行了讨论。最后，在硫系，分子，碲化物和磷酸盐玻璃的结构因子测定的例子进行了讨论，以说明中子衍射技术的实用性。
An introduction is given to structure factor determination by means of neutron diffraction. The method of isotopic substitution, which allows us to separate the partial correlation functions, is also presented. Suitable instruments, the experimental procedures, and corrections are described. Other less-conventional techniques such as isomorphic substitution and anomalous dispersion are also discussed. Finally, examples of the structure factor determination in chalcogenide, molecular, telluride and phosphate glasses are discussed in order to illustrate the usefulness of the neutron diffraction technique.
