Precision coating is a very important process in manufacturing of thin films. Among many coating techniques, slot coating may be the most promising in developing high precision coating process due to its versatility and controllability. Fundamentals of slot coating have been studied by many pioneer researchers. However, two topics: use of polymer additives and discrete operation remained relatively largely uninvestigated, especially in terms of their basic mechanisms. These two topics are studied in this thesis using theoretical analysis and experimental methods.

精密涂布技术是未来薄膜技术的重要发展方向，在诸多的涂布技术中，狭缝式涂布是用途广泛且有深厚发展潜力的一项，前人的研究阐明了许多狭缝式涂布的疑难问题，然而，随著精密涂布技术的发展，高分子添加剂与非连续操作逐渐地应用於狭缝式涂布之中，这两个研究课题目前并未发展出适当的理论来说明其机制，本研究以理论与实验的方法对这两个课题进行研究。

CPU of airborne computer implements existing data acquisition of unpiloted vehicle with low efficiency. To improve the efficiency and to solve problems on reliability, real time and precision, the design of acquisition system based on DSP which can make a circuit acquisition for 54 channels data is put forward.
