Result］ It could be concluded through analyzing the model that both the mass uncertainties of quinoline phosphomolybdate precipitates and tested samples were from the resolving power and precision of balance and its maximum tolerance in assay certificate; the uncertainty brought in by volumetric flask was from the permissible error of 250 ml volumetric flask, the operation of increasing the volume to scale of volumetric flask while diluting solution and the difference between experimental temperature and the temperature at the time when the volumetric flask was calibrated; the uncertainty brought in by pipette was from the permissible error of itself, the operation of increasing the volume to intake scale while taking solution and the difference between experimental temperature and the temperature at the time when the pipette was calibrated.

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. We adopted swab from the pharynges respectively, inoculated it in agar plate, isolated the bacteria, and evaluated the distribution and variation of the microbial population in pharyngeal portion.

此论文通过借鉴国内外对直升机旋翼动平衡试验台系统设计的经验，确定采用当今较新与较成熟的技术构建了集数据采集与控制为一体的试验控制系统来满足整个动平衡试验的要求。另外还对直升机旋翼动平衡试验台系统方案设计中各分系统作了简单介绍，并通过和以往系统比较分析，在借鉴前人经验的基础上进行了创新。此论文主要介绍了直升机旋翼共锥度测量分系统的设计与实现。

The calculated and experimental results of phonon structure fit well in the vicinity of the high symmetry point, while in that of low symmetry point X,the calculated results are higher than the experimental data, which results in the frequency shifts in the phonon density of states.

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。
