1. The synthesis and refinement of 2, 3 dichlorobenzaldehyde are described in this thesis. By the new refinement the total receipt rate is raised from 32. 6% to 45%. 介绍了2，3二氯苯甲醛的合成及提纯方法，采用新的提纯方法，可使总收率由文献值32。6%提高到45%。
2. First, these data will be made a local decision by decision-maker, and then ad- justed in the period of Deta Refinement and Object Refinement, last will be transferred to fusion center. 这些数据首先由决策器进行本地决策，在通过数据提取和对象提取阶段的时间和空间校准之后，传送到融合中心进行决策。
3. the problem of local statistical feature value refinement has been studied, and a refinement method has been given which can decrease the boundary effect in calculating the feature value. 研究了局部统计特征值的改进问题，给出了一种对所提取的纹理特征值的改进算法，一定程度上克服了计算纹理特征时的边界效应。
4. The religion most prevalent in our northern colonies is a refinement on the principles of resistance:it is the dissidence of dissent(Edmund Burke. 北方殖民地普遍的宗教是对拒绝原则的巧妙的改进：它是对持不同意见人的异议（爱德蒙德·伯克）。
