The performance research on a two-phase gas-liquid electrostatic induction nozzle was carried out in the lab. The results showed that the droplets deposition and coverage ratio on the upper leaf surfaces achieved by electrostatic spraying were increased by 43. 03% and 22. 07% , respectively. The coverage ratio on the down leaf surfaces was up to 30. 95% ; when gas flow rate was 1.4 m3/h, liquid flow rate was 60 mL/min, voltage was 1 000 V, charge-to-mass ratio could reach to 3.2 mC/kg, which was high enough for electrostatic spraying. The optimum work parameters were: gas-liquid ratio of 0. 18, spraying angle of 0°, and voltage of 1 000 V.%对研制的气液两相感应式静电喷头进行了性能试验研究.结果表明:与常规喷雾相比,雾滴在叶片正面的沉积量和覆盖率分别增加了43.03％和22.07％,且在叶片背面覆盖率达30.95％；当气体流量为1.4 m3/h,喷量为60 mL/min,电压为1 000 V时,荷质比可以达到3.2 mC/kg,可以有效增加荷电沉积；最优工作参数组合为气液比0.18、喷雾角度0°、电压1 000 V.
