At first, Professor Chou hoped we could introduce "Ice Shavings", because it's a local and common snack in Taiwan and it could attract the masses. However, the topic of the" Food Culture" was deleted on account of the difficulty in division of labor. It takes about forty teachers and students two months to finish the project; it's far from easy!

主题是由指导教授-周教授决定，本来教授希望能介绍「剉冰」，因为那是台湾一样相当有特色且普遍的冰品小吃，很能吸引大众的兴趣，但由於分工不易，所以改成「饮食文化」，由四所学校，三、四十位师生於两个月内完成，相当不容易！

In this study, the CPE processes of four different kinds of polyaromatic hydrocarbons, acenaphthene, anthracene, phenanthrene and pyrene, with two kinds of silicone surfactants, DC-193 and DC-190, were studied separately, and four different assisting methods for the phase separation of the CPE process including heating at a higher temperature, adding salts, centrifugation and stirring were introduced, respectively.

今利用两种聚醚型有机硅表面活性剂DC-193和DC-190，对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究，分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。通过测定表面活性剂富集相的体积百分率Vs/随时间的变化和最终的萃取率，研究上述四种不同辅助方法对相分离行为和萃取性能的影响。

The adjoint operator method and the theory of normal form are used to investigated the normal forms in the four dimensional nonlinear systems with cubic nonlinearities.
