激光法测量雾滴的直径保定地区农机研究所宋林平雾滴直径的大小和分布是表明喷雾器械性能优劣的一个重要指标。在喷雾器械的研制试验阶段、制造的质检过程和推广试验中，经常需要测量雾滴的直径。常规的雾滴测量方法虽有多种，但基本以手工操作为主，需要经过采样垫制作、... Measuring the Droplet Diameter by Laser Method Song Linping, Institute of Agricultural Machinery, Baoding, China The size and distribution of droplet diameter is an important indicator of the performance of the spray instrument. It is often necessary to measure the diameter of the droplet during the development and testing of the spray device, the quality control process and the extension test. Although there are many kinds of measurement methods of conventional droplet, it is mainly based on manual operation and needs to be made through sample pad.
