起源於噴墨印表機噴印技術的微液珠噴射技術，因可以應用在電路基板配線、彩色濾光片、微泵浦燃油噴射、奈米尺度之超精密加工、以及生醫工程等方面，而受到極大的注目。
本論文以一套壓電式噴液設備，進行去離子水及乙二醇液體的液滴噴射實驗，觀察並探討操作頻率、脈衝時間、脈衝電壓、脈衝型態以及噴射液體等實驗參數，對液滴噴射之情形、液滴之形成機制及液滴飛行之情況。以求找到最佳的液滴型態，即愈小的液滴體積、愈小的附屬液滴、無二次液滴、愈快的飛行速度、愈大的操作頻率，以及能得到最佳液滴型態之液滴噴射條件。同時以一套針對壓電式微液珠噴射技術所建立的3-D模擬系統，模擬去離子水及乙二醇液滴之液滴噴射。
在液滴的噴射實驗中，木論文找出實驗參數對液滴噴射之影響，並得到兩種液滴噴射的最佳條件。並將3-D模擬系統模擬之結果，與實驗進行比對，以驗證此模擬系統的準確性。

Micro-droplet injection technology, originated from inkjet printer’s inkjet technology, was paid to a lot of attention because of its great ability to wide application, such as IC interconnect, color filters, micro fuel pump, nano-scale working, and Bio-medical aspects.
This thesis observed and studied the influence of operation frequency, pulse time, pulse voltage, pulse type and injection fluid to droplet injection, droplet dynamics, and droplet aviation by a piezoelectric inkjet device injecting DI water and ethylene glycol. This thesis looked for the best droplet form, that is, smaller the droplet volume, smaller the satellite droplets, no second droplets, faster the droplet speed, and higher the operation frequency, and the conditions to acquire best droplet form. This thesis also simulated the droplet injection of DI water and ethylene glycol by a 3-dimensional simulation system.
With the droplet injection experiments, this thesis obtained the influence of experiment parameters to droplet injection. This thesis also obtained the conditions to acquire best droplet form. 3-D simulation results was also compared with experiment results, to verify its accuracy.
