摘要
喷灌喷洒水滴直径是衡量一个喷头性能的重要指标。针对传统喷灌水滴直径测量较为复杂的问题,提出基于Adobe 7.0软件测量水滴直径的方法,运用该方法对色斑直径与水滴直径关系进行了率定,并对雨鸟系列喷头的水滴直径进行了测量,得到了3种水滴平均直径的关系、水滴直径与喷头距离的关系以及水滴累积体积百分数曲线图。
Based on the Adobe 7.0 software, proposed the new water droplet diameter measurement method. The method evidently decreased the heavy task in traditional methods. The relationship of color spot diameter and droplet diameter was confirmed, and the water droplet distribution was measured. We got the three kinds of mean droplet diameter, correlation between water droplet diameter and the distance to the nozzle and calculate the droplet volume percent accumulated curve. We proposed a new method to measure the droplet diameter, improve the measuring precision and reduce the work load greatly.
