FITC can inhibit the antimonite-stimulated ATPase activity of ArsA and a combination of ATP and antimonite can completely protect ArsA from the inactivation of FITC. The Lys residue in the glycine-rich loop in ArsA is possibly one of the sites for FITC modification. Antimonite can induce the fluorescence resonance energy transfer between FITC and TRITC that separately labeled on different ArsA molecules.

研究还发现FITC对ArsA的ATP酶活性有抑制作用，ATP和SbO〓与ArsA的结合完全拮抗这种抑制，说明ATP和SbO〓与ArsA的结合能够引起ArsA产生一种完全不同于它们单独与其结合时的构象变化，从而使ArsA上FITC的修饰位点变得不易接近，同时ATP结合位点内的Lys可能是FITC在ArsA上的结合位点之一。

In this thesis, we implement a computational procedure to categorize and classify 3-D objects from their contour under a simple environment. First, we use foreground detection, Canny edge detection and speedy GVF snake to obtain the object's contour. The contour is then used to establish the object's features. Two databases are built using methods which compute similarity by modified aspect-combination algorithm proposed by Cyr and Kimia and new proposed aspect-combination algorithm. By using these two databases, we recognize 3-D objects using four recognition methods and compare their performance. Finally, a conclusion is made that our newly proposed algorithm is better than the modified algorithm proposed by Cyr and Kimia.

在本论文中，对一个在单纯环境下的三维物体，由撷取到辨识出此物体做了一个完整的实现，首先，利用前景侦测结合肯尼边缘侦测法和加速的梯度向量流动态轮廓侦测法，来得到物体轮廓，接著利用此轮廓找寻出物体的特徵，然后配合计算相似度的方法，代入修改后的Cyr and Kimia的外观结合演算法（aspect-combination algorithm）和新提出的外观结合演算法去建资料库，然后，对於三维物体则依据两种不同方法所建出的资料库，利用四种辨识的方法来辨识并比较其结果，最后得出新提出的外观结合演算法是优於修改后的Cyr and Kimia的外观结合演算法的结论。

The interactions of dsDNA and ssDNA with two osmium complexes have been studied by surface electrochemical methods based on DNA modified electrode. It is found that both osmium complexes bond DNA with electrostatic interaction.

After the identification of SARs in Attacus ricini rRNA gene, its rRNA gene and NTS were also found to have the ability binding with the nuclear scaffold of Saccharomyces cerevisiae. The 1kb NTS fragment which can bind clearly with nuclear scaffold of Attacus ricini was the chief fragment binding with yeast nuclear scaffold. This indicated the homology between this two kinds of SARs and provided an evidence for the evolutionary conservation of SARs.

在鉴定蓖麻蚕rRNA基因中具有骨架结合区域之后，利用体外结合的方法发现，蓖麻蚕rRNA基因及其非转录间隔区片段也具有与酵母核骨架结合的能力，尤其是能与蓖麻蚕核骨架结合的非转录间隔区1kb片段，也能明显地结合于酵母核骨架，这一结果表明二者的SAR顺序具有一定的同源性，为骨架结合区域具有进化保守性提供了又一证据。

Through the nowadays situation of the international community insurance industry and the developments of the present condition with the economy, we can see that the environment liability insurance starts presenting the tendency of insurance industry being combined with banking and stock certificate industry, the insurance means combined with tax means, the insurer combined with insured benefits, the insurer combined with insurer, the insurance liability insurance compensation combined with environmental indemnification fund and the insurance being commercial combined with the insurance acculturates increasingly.

The results show that 42.86% topsoil samples are polluted by Cadmium, soil synthesis pollution index is moderate, Cadmium pollution degree of topsoil correlate with the environment of sampling sites. The results also show that exchangeable Cd, carbonate-bound Cd, organic-bound Cd and residual Cd are found in all soil samples except for Fe-Mn oxide-bound Cd. Furthermore, the concentration of exchangeable Cd and carbonate-bound Cd, both which have high biological validity, is high. Humus has a certain correlation with exchangeable Cd, organic-bound Cd and residual Cd, and has no obvious correlation with other chemical speciations. Any chemical speciation of Cd has no obvious correlation with pH and total Fe of soil samples. Cadmium in topsoil can be eluviated by acid solution, the quantity of Cadmium eluviated by redistilled water is little. With the rise of pH of eluviating solution, eluviated Cadmium quantity decrease. For the same soil sample, the lower pH value of eluviating solution is, the more fast the Cadmium is eluviated, and the more thequantity of Cadmium is eluviated.

研究结果表明：成都市表生土壤样中有42.86%受镉污染，镉综合污染水平达中度污染，成都市表生土壤镉污染程度与采样点周围环境表现出一定的相关性；除铁锰氧化物结合态镉在部分土壤样中未检出外，所有土壤样均含有可交换态镉、碳酸盐结合态镉、有机结合态镉、残留态镉，且生物有效性较高的可交换态镉和碳酸盐结合态镉占总镉量比例较高；成都市表生土壤中的腐殖质与可交换态镉、有机结合态镉、残留态镉有一定相关性，与碳酸盐结合态镉、铁锰氧化物结合态镉相关性不显著；各形态镉与土壤pH值和全铁的相关性均不显著；土壤中的镉可被酸溶液淋出，重蒸馏水淋出镉量十分微小；随着淋滤液pH值的升高，土壤样的镉淋出量下降，且0～5小时时段的镉淋出量占镉总淋出量比例下降，5～30小时时段的镉淋出量占镉总淋出量的比例上升，对同一土壤样而言，酸度大的淋滤液比酸度小的淋滤液淋出镉速度更快，淋出镉量更大。

For the high affinity sites, binding constant decreases with the decrease of the alkyl chain lengh in the surfactants, but for the low affinity sites, binding constant increases and are not distinct when the alkyl chain is dedocyl. The binding sites are related to the alkyl chain lengh, not for the number of hydrophile groups and temperature.Isothermal titration calorimetry has been used to observe the enzyme-catalyzed hydrolysis reaction of urea.
