平均粒徑-
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。 -
Because the structure of horomill is not prefect in practice, in the second section design horomill by consulting the structure of roller grinding and applying concurrent engineering, and empolders secondly autocad2000 by using visual basic 6. 0, and sets up parameter gallery of horomill. in the third section, the dynamic model of horomill is developed. the relationship equation between energy consumption and press, and the relationship equation among the diameter of the cylinder, the diameter of roller and the average particle size are established
由於筒輥磨的結構在實踐應用中並不十分完善，本文參考了輥式磨的結構特點，利用并行工程技術設計出變徑離心式輥碾磨機，並且應用visualbasic6 . 0對autocad2000進行了二次開發，建立了筒輥磨的參數化圖庫。 -
Pilot - scale experimental results showed that, comparing to conventional gravity filtration, the up - flow filtration has greater capacity in containing removed suspended solid and producing filtrate under the test conditions. coarse media with particle diameter ranging 0. 63 - 2. 00mm were used in order to apply relatively higher backwash rate of 21 l / ( m2. s ) for achieving better media clean - up after a filtration run. under the test conditions, the media thickness ranging 82 - 85 iron, water temperature ranging 6 - 27, and influx turbidity of 30 ntu, it achieved the results of the average filtration rate ranging 16 - 18 m / h, the average effluent turbidity of 1 ntu, and action cycle ranging 14 - 24h
