解釋
功率變化率-
According to the experimental data of droplet size 、 particle spectrum range 、 droplet cone shape 、 flow rate 、 cover area and cover area rate which obtained through changing the pressure of power sprayer and the nozzle diameter in greenhouse ， this paper made comparative analysis on atomizing performance in same pressure and different nozzle type between same nozzle type and different pressure. the conclusion is that : the ejection rate and the droplet cone shape change with the variation of pressure and nozzle diameter ， average particle diameter decreases obviously and particle quantity increases obviously with the increase of pressure and decrease of nozzle diameter. these results will lay experimental foundation for precise spraying 、 low pollution and highly effective operation
本文根據溫室內動力噴霧機壓力與噴嘴孔徑的變化影響霧滴大小、粒譜范圍、霧錐形狀、流量、覆蓋面積及覆蓋面積率的試驗數據，對相同壓力下不同噴嘴型號和相同噴嘴型號時壓力不同時的微粒化性能進行對比分析和研究，得到如下結論噴出量與霧錐形狀隨著壓力和噴嘴孔徑大小變化而變化；平均粒徑隨著壓力的增加和噴嘴孔徑的減小而明顯減小；粒數隨著壓力的增加和噴嘴孔徑的減小而明顯增多，為精噴量、低污染、高防效的防除作業奠定了實驗基礎。 -
