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.

Results indicate that as the molecular mass of polyethylene glycol increases, the conductance is increased obviously, and the surface tension is decreased from 36.28 mN/m to 31.30 mN/m, while the cloud point is increased from 39.6 ℃ to 58.9 ℃. Their emulsifying abilities to BA, MMA and BMA are superior to that of OP-10, and the surfactants is homopolymerize or copolymerize with acrylate at 70 ℃ under the initiation of AIBN.

结果表明，随聚乙烯醇分子量的增加，非离子表面活性剂的电导率显著增加、表面张力由36.28 mN/m降低至31.30 mN/m、浊点由39.6 ℃增加至58.9 ℃，对丙烯酸丁酯、甲基丙烯酸甲酯和甲基丙烯酸丁酯的乳化能力均优于常用乳化剂OP-10，以AIBN作引发剂在70 ℃下既能均聚又可与丙烯酸酯进行共聚反应。

The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.

实验部分采用以石油醚脱脂，甲醇为溶剂的回流提取法来提取植物多酚，用显色反应检识酚羟基；采用紫外分光光度法对多酚粗体物进行总多酚含量的测定；选取了聚生小穴壳菌、立枯丝核菌、梨叶点霉等10株常见农林业致病真菌，采用试管液基稀释法对多酚粗提取物进行了抗真菌活性筛选试验，并测定其最低抑菌浓度；采用柱层析法和薄层层析法对其中抑菌效果较好的龙血竭进行分离分析，根据其中3种化合物的光谱数据UV、IR、~(13C-NMR、1H-NMR和MS鉴定其结构。

Unifoliate opposite, rich change is simple, xiecheng grows elliptic or long ellipse to wrap around needle form, acute of account of end of end of blade is pointed, the leaf carries dot having gland on the back, xie Changyao 4 to 4.5 centimeter, xie Kuan is made an appointment with 1.2 to 1.5 centimeter; Get together unripe or 繖 inflorescence armpit is very unripe, grey is lubricious, petaline 3 reach 4, the brim has fluff, stamen is most; Berry is shown globose, mature moment can turn by green for black.

单叶对生。富革质，叶呈长椭圆形或长椭圆披针形，叶端尾状锐尖，叶背有腺点，叶长约4至4.5公分，叶宽约1.2至1.5公分；聚繖花序腋生或顶生，花白色，花瓣3至4枚，边缘具有茸毛，雄蕊多数；浆果呈球形，成熟时候会由绿色转为黑色。
