摘要
研究了几种液力式雾化喷头的雾滴直径分布规律。根据实测的数据，采用χ２假设检验的数理统计方法，确定了其雾滴直径的数量分布一般服从对数正态分布或贯山棚泽分布规律。
The paper studied the droplet size distributions of several kinds of hydraulic nozzles applied to equipment for plant protection, air washer and spray irrigation. By a laser droplet analyzer, the number and the volume of different droplet size were measured under different spray pressure from 0 10 MPa to 0 30 MPa. Based on these data, the pattern of droplet size distributions, which were expressed in probability density function, were studied by the method of mathematical statistics of χ 2 hypothesis testing. It showed that the droplet size follows the lognormal or Tsuranuyama Tanasawa distribution in number, and the normal or RosinRammler distribution in volume.
