| 中文摘要: |
| 通过建立一维喷墨模型，对压电式喷墨过程进行了阶段分析，并结合牛顿第二定律、动量守恒定律和能量守恒定律，对作用在压电元件上的电压与相应的压力之间关系进行了分析，对油墨在管腔中的运动进行了描述，并分析了液滴形成的条件以及形成液滴的大小和速度变化，最后通过实验分析了表面张力和喷射速度对墨滴形成的影响。 |
| 英文摘要: |
| One-dimensional ink-jet model was established. Stage analysis was carried out on piezoelectric inkjet process. The relation between voltage and the corresponding pressure was analyzed combined with Newton's second law, the law of conservation of momentum, and energy conservation law. The movement of the ink in nozzle was described. The condition of drop formation and the droplet's volume and speed was analyzed. The influence of surface tension and jet speed on ink drop formation was analyzed through experiment. |
