Methods: The author chose randomly sixty healthy children as the control group and one hundred and sixty children with asthma in acute period before ICS therapy as the experimental group. The experimental group were treated with ICS therapy and then eighty-nine children of this group were followed up for 3 months ,sixty-eight for 6 months and sixty for 12 months. The ICS in the study was budesonide with the trade name as Pulmicort.

发现在高对称q点附近，声子结构的计算与实验数据符合很好，而在对称性较低的X点附近，计算结果偏大于实验数据，导致了声子态密度计算结果"频移"现象的发生。

The teaching term took sixteen periods. The curriculum contained two topics,"acid and base", and "Taiwan's climate". Experimental treatments were teaching method. The research tools utilized in the study were " Science Concept Comprehension Test, Science-related Attitudes Scale, Problem Solving Ability Test and Questionnaire on the Attitude toward Science Teaching". A pretest administered before the experimental treatment and a posttest was held after the treatment. The data of SCCT, SRAS, and PSAT collected from pretest and posttest were analyzed by two-way ANOVA. Responses from the QAST were analyzed by ANOVA.

本研究的实验处理为以问题为中心的合作学习教学，研究工具包括「科学概念理解问卷」、「科学相关态度量表」、「问题解决测验」、「对自然科的教学态度问卷」、「教学检核量表」及「问题中心教学自我评估量表」，分析「科学概念理解问卷」、「科学相关态度量表」和「问题解决测验」资料时，以前测经验和教学法为自变项，后测为依变项，进行二因子变异数分析；「对自然科的教学态度问卷」采用单因子变异数分析；「教学检核量表」及「问题中心教学自我评估量表」则用来检核研究者的教学是否符合研究者的研究设计；在质性资料的部分，则分析学生的上课纪录、教师教学反省纪录及对自然科教学的态度问卷的理由。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.
