射流直径 meaning in Chinese

jet diameter

The key dimension of fan have been designed . experimentally analyzed with water spray analyzing the number distribution and mass distribution of drops when use different water volume , the main diameter range is from 20 to 50 u m . the total drop quantity is 90 percent which diameter is less than 40 u m . using proof analyzing , the water volume have litter effluence the evaporative rate , and the whole drops can evaporate fully
对冷风机的射流理论进行分析，研究冷风机的射流直径和射流范围，并对冷风机的安装高度，安装距离进行分析；通过原理设计冷风机通风和喷雾关键部件的结构尺寸，对冷风机的通风和喷雾进行检测，雾滴直径在不同的喷雾量下变化不大，基本保持在20 - 50 m之间，在不同的喷雾直径下，雾滴直径90都在40 m以内，使用数理统计方法分析雾滴粒度分布规律，根据实际数据和参数估计的进行假设检验，结果显示理论和实际数据基本吻合，冷风机的雾滴能充分的蒸发。
