To the problem that large-scale labeled samples isn't easy to acquire in the course of SVM training, the active learning strategy is used in the SVM training and an incremental training algorithm of active SVM based on the uncertainty based sampling of distance ratio is proposed in the paper. The experimental results show that the active SVM learning strategy can considerably reduce the labeled samples and costs compared to the passive learning method, and at the same time it can ensure the accurate classification performance is kept as the passive SVM and also expedite the SVM training.

针对 SVM训练学习过程中难以获得大量带有类标注样本的问题，本文将主动学习策略应用于SVM增量训练中，提出了一种基于距离比值不确定性抽样的主动SVM增量训练算法，实验结果表明在保证不影响分类精度的情况下，应用主动学习策略的SVM选择的标记样本数量大大低于随机选择的标记样本数量，大大降低了标记的工作量或代价，而且训练速度同样有所提高。

The effects of increasing the stereospecilicity is due to deactivation of different selectivity for both atactic and isotatic active centers and the deactivation of atacitic active centers is much greater than that of isotactic active centers.

EB、DIBP和TMP用作Din的效果则各不相同。烷氧基硅烷等Dex提高等规度的作用是由于它们选择性地使无规活性中心失活大大高于等规活性中心。

Concerning about the active computer vision, the thesis put an emphasis on the stereo matching scheme based on multiscale wavelet edges and other active control plans such as depth from focus, convergence motion. Combining these schemes with the point correspondence problem in color image pairs, a compositively active and integrated strategy is developed successfully for visual processing.

在视觉影像的主动分析方法中，论文着重探索了基于多尺度小波边缘的立体匹配控制策略、基于焦距的深度测量方法、基于聚散运动等多种主动控制方法，并将这些方案连同彩色立体图象中的点对应问题一起，相互有机结合起来，构成了一个较为完整的面向视觉影像处理的主动、复合分析方案。

目前工业上采用的活性炭提取液脱色存在的主要问题是，活性炭中难免夹带有灰黄霉素，废弃活性炭的堆积与处置对环境造成污染。

The types, attributes, generation mechanism and enzyme activity of eliminative system of active oxygen species in plant are presented in this paper. In addition, the possible function of active oxygen species that may contribute to disease resistance and the difference of active oxygen species between compatible reaction and incompatible reaction in plant- pathogen interaction are discussed.
