摘　　要：提出了利用雾滴影像反求确定雾滴直径的测定方法。首先利用显微镜及其照相机或CCD镜头拍摄雾滴图像，利用计算机软件AutoCAD对图像进行标注，找出雾滴影像直径与雾滴实际直径之间的对应关系。再利用接口程序处理图形交换文件．DXF，生成雾滴直径数据文件。最后应用Excel进行统计分析，得出雾滴体积中径分布曲线，为新型喷雾植保机械（雾滴直径为20～500μm）的研究提供了一种直观简捷的方法。A measuring method for droplet diameter using its image is provided. Firstly, the photo of droplets with microscopy or CCD would be taken. Then the image of the droplet diameter is marked and corrected with computer software AutoCAD, which can find out the relationship between droplet image size and its reality size. Secondly, the data file of droplet diameter with DFX format is created. Finally, a curve of the diameter of volume of the droplet distribution is obtained by the way of statistics and analysis using MicroSoft Excel. This method offers an easy way for measuring droplet diameter from 20μm to 500μm.
