This study is based on the screening technique that identifies the factors sensed by the experimenter. In order to determine the optimum processing conditions and find the combination of parameters that maximize the productivity in the experimental phase, a geometric illustration of the response has been made. The results are： the pores radius （4 μm）, surface tension （62.5 mN/m）, depth （10 μm） and viscosity （2,000 Cp）.展开更多

The results of the teaching and the investigation conducted by the author show that the choice of the teaching materials and the topics for the class must be included in the teaching plan. Besides, this paper also probed into the most difficult topic, the easiest topic, the topics that need to be explained more and the topics that need to be explained less in class; and the similarity and differences of the teaching contents for students in different grades are also analyzed. In the end, proper sources of the comparison of English and Chinese languages and cultures are revealed in order to enlarge students＇ knowledge and improve their competence in using English.展开更多
