综述了用于结冰研究的液滴尺寸测量仪器。这些仪器包括前向散射光谱仪探头、光学阵列探头、相位多普勒颗粒分析仪、马尔文颗粒尺寸分析仪、滑油技术和旋转多缸。该报告重点介绍了这些仪器的工作原理，以及在结冰设施中使用这些仪器时的实际注意事项。本SAE航空航天信息报告（AIR）的目的是提供有助于选择、操作和评估用于飞机结冰研究和开发时液滴尺寸测量仪器局限性的信息。

A review of droplet sizing instruments used for icing research is presented. These instruments include the Forward Scattering Spectrometer Probe, the Optical Array Probe, the Phase Doppler Particle Analyzer, the Malvern Particule Size Analyzer, the oil slid technique, and the rotating multicylinder. The report focuses on the theory of operation of these instruments and practical considerations when using them in icing facilities.The purpose of this SAE Aerospace Information Report (AIR) is to provide information that is useful for the selection, operation, and appreciation of the limitations of droplet sizing instruments when applied to aircraft icing research and development.
