| 摘 要： | 为了研究气助式静电喷雾中，药液雾化特性对其靶标背部沉积效果的影响，采用Ф80mm的西红柿果实作为靶标，配制1g／L的刚果红溶液模拟农药进行喷雾试验．运用OLID测试系统对不同施药条件（气体压力、静电电压、喷雾距离）下药液的雾化特性进行了测试，借助分光光度计定量分析靶标背部沉积量，结合试验结果对药液雾化特性与靶标背部沉积效果的关系进行了分析和讨论．结果表明：非静电喷雾时，雾滴不易粘附于标靶背部，与荷电喷雾时相比，背部沉积量较小可以忽略；在气动力和静电力的前后作用下，雾滴的粒径随气体压力、静电电压的增加而减小且分布愈均匀；增加气体压力、静电电压均可提高药液靶标背部的沉积量，其中静电电压影响最大；荷电啧雾时，雾滴的粒径愈小分布愈均匀有利于荷电药液在靶标物背部沉积．

| Abstract: | In order to study the atomization characteristics of air-assisted electrostatic spray field and its effect on pesticide target backside deposition,the spraying experiment was carried out by using a tomato fruit with a 80 mm diameter as the spraying target and preparing a Congo red solution with a concentration of 1g/L instead of pesticide.The atomization characteristics was tested and analyzed in various conditions using OLID measurement system.The target backside deposition effect was quantitatively analyz... |
