摘　　要：云粒子测测量系统是开展云降水物理和人工影响天气研究的关键测量仪器。目前我国使用的这类仪器主要是由国外进口。不仅仪器的定标依赖于厂家使得用户在时间和经济上的代价很大,而且传统的玻璃珠定标方法也存在易粘连等缺陷。针对这个现状,提出一种新的定标方法。利用成熟的喷墨打印技术和视觉测量技术,产生可控、稳定的5种直径(10~50μm)连续微水滴,来定标云粒子测量仪器。本文详细描述了实现此定标方法的系统原型结构,分析了影响系统工作性能的因素,通过对同一CDP(Cloud Droplet Probe)探头定标与传统方法进行对比。结果表明,此方法能够满足云粒子测量系统的定标需求,该定标方法较传统方法易于控制且性能良好。A cloud particle measurement system is a key instrument to carry out the research on cloud precipitation physics and weather modification. In China, most of the instruments are currently imported from overseas. Not only the calibration of the instrument depends on the manufacturers abroad, and costs users＇ large amount of money and time, but also the traditional glass bead calibration method has defects of easy adhesion and so on. Based on the present situation, a new calibration method is proposed, which utilizes the sophisticated inkjet printing technology and visual measurement techniques to produce controllable, stable continuous water droplets of 5 diameters （from 10μm to 50μm） for the calibration of the instruments. The prototype structure of the system is described in detail. The factors affecting the working performance of the system are analyzed. The same Cloud Droplet Probe （CDP） is calibrated, and the new method is compared with the traditional method. The results show that the method can meet the needs of calibration of the cloud particle measurement system, and the equipment performs well and is easy to control.
