文档介绍：Design of a new type vibrating mesh nebulizers based on piezoelectric actuator Abstract
The electronic balance and a video camera were used to catch the data of quality change in the working process of nebulizers. It was demonstrated that the flow rate was affected by the pore size and the viscosity of liquid, and the bubble was the main reason of the changes in the flow rate curve. Scanning electron microscopy (SEM) was chosen to to determine the size of the water droplets in frozen state, and the particle size proved to be between 5 and 20 micrometers, suggesting a great potential for submicro- & nano- manufacturing.
