• 中文摘要： 本文針對常見於擠壓式塗佈操作中之管道流及斜板流兩連續程序段, 進行介面穩定度分析探討。在本文中, 我們提出介面黏度及彈性差異的穩定度機制以及鑑別出各種機制競爭後的結果。根據所提出之穩定度機制, 我們可以說明存在於兩流動程序段之介面穩定度之差異。最後我們的結果顯示, 在適當安排流體流變特性及幾何因素下, 同時適用於兩流動程序段的全波長穩定操作視窗是存在的。
• 英文摘要： The stability analysis for two consecutive flow sections that occurring in the slot coating processes is performed in this work. The mechanism for linear interfacial stability and the consequence of competition between mechanisms, due to viscosity and elasticity difference across the interface, have been proposed and identified. Based on the proposed stability mechanism, we may illustrate the discrepancy of interfacial stability characteristics between two consecutive flow sections. Our results show that common stability operating windows are obtainable if an appropriate arrangement of rheological properties and geometric factors is made.
