| 主要比较了无水乙醇在单根、线性单排、双排毛细管道条件下,其稳定的锥-射流模式喷洒的几项重要指标：在稳定的锥-射流喷洒模式下,雾化的起始电压、电流以及粒径与流量的关系。在实验过程中,由于温度、湿度等环境的不稳定以及装置的制作/安装过程中的精密度不高等因素的影响,实验现象细节存在少量不确定性。但是单管道、单排管道、双排管道三种情况下其起始电压、回滞电压、电流、粒径与流量之间的关系有着相似的规律。即在稳定的电压下：(1)电雾化总流量(Q)的1/2次方与总电流(I)之间成正比；(2)电雾化总流量(Q)的1/2次方与雾化液滴的粒径均值(D)成正比。 |

| Several key indexes of ethanol stable cone-jet spraying mode were compared under conditions of single capillary, one-line capillary, two-line metal capillaries, respectively. These indexes include relations among initial voltage of spray, initial electric current, droplet size and flow rate. During the experiment, some small uncertainties were unavoidable due to the temperature/humidity instability and lack of enough precision in manufacturing and assembling processes. But the relations among initial/return voltage, electric current, droplet size and flow rate present similar patterns under conditions of single capillary, one-line capillary, two-line metal capillaries, respectively. Namely, under stable voltage condition, (1) the 1/2 power of total spray flow rate (Q) is linearly proportional to the total electric current (I); (2) the 1/2 power of total spray flow rate (Q) is proportional to the mean droplets diameter (D). |
