回顾了光子相关光谱（PCS）作为粒度测定实用工具的可能性和局限性。在这一部分中，简要概述了最常用的数据分析方法。通过与不同类型的用户（工业和学术研究小组和制造商）的比较研究来评估粒度分布测定的实际性能。 PCS 结果还与电子显微镜 (EM) 和静态光散射 (SLS) 结果进行了比较。由此证实，PCS 在几分钟数量级的测量时间内可以获得的有关粒度分布的可靠信息量受到数据反演过程的不良条件等因素的限制。尽管如此，从 PCS 测量中获得的信息与 EM 和 SLS 结果基本一致。
The possibilities and limitations of photon correlation spectroscopy (PCS) as a practical tool for particle sizing are reviewed. In this part the most frequently used methods of data analysis are briefly surveyed. The practical performances for the determination of particle size distributions were evaluated by a comparative study with different kinds of users (industrial and academic research groups and manufacturers). The PCS results were also compared with electron microscopy (EM) and static light scattering (SLS) results. Thereby it was confirmed that the amount of reliable information that can be obtained by PCS about particle size distributions with measuring times of the order of minutes is limited by the ill-conditioning of the data inversion procedure, among other factors. Nevertheless, the information obtained from the PCS measurements agrees essentially with the EM and SLS results.
