The results revealed that iontophoresis could significantly improve the penetration of SLN. The fluorescence of images indicated that the accumulation and the depth of QDs-SLN reached in skin increased with times. Anodal delivery of QDs-SLN resulted in a higher accumulation of QDs-SLN in skin than those of cathodal delivery. Furthermore, the vertical images of skin showed that fluorescence assemble in follicle and dermis, indicating that follicle and the junctions between the corneocyte clusters provide the pathway for SLN penetration into skin.

In the former growth period, the accumulation of various nutrient components was gradually increasing and the declining rate of crude protein content was slow; in the later growth period, the accumulation of all kinds of nutrient components easily being digested was slow until stopped. The best utilization time of Arundinaria argenteostriata was in the period from May to Sept., with the content of crude protein of 13.78%-15.10%; crude fat, 3.77%-8.49%; soluble sugar, 14.57%-18.47% and acid detergent fiber,

There were larger differences in element contents between different organs of mangroves, while sodium distributed equally in the different organs of \%C. eyrei.\%(2)The osmoregulation of 5 mangroves was mainly fulfilled by salt accumulation.(3)Salt exclusion by roots was the most important salt tolerant mechanism of all mangroves. Keeping lower salt contents in above ground organs was the common feature of all mangroves.(4)Except the efficiency in salt exclusion by roots, no apparent deficiencies in element accumulation and distribution could be found between salt excluders \%(K. candel, B. sexangula\% and \%R. stylosa)\% and salt secreters \%(Avicennia marina\% and \%Aegiceras corniculatum).

结果表明：(1)红树植物体内存在一有效的盐分重新分配机制，各器官之间盐分含量差别较大，而甜槠植物体内Na分布相对比较均匀；(2)这5种红树植物主要是通过积累盐分来抵御生境高盐引起的渗透胁迫；(3)根系拒盐是所有红树植物最重要的排盐机制，在满足细胞渗透调节的前提下，保持地上部分器官较低的盐分浓度是所有红树植物的共同特点；(4)拒盐红树植物与泌盐红树植物除根系排盐效率上有所差别外，在植物体各器官元素积累及分配方面，没有明显的差异。

Nutrition solution culture, ICP-AES, the differential centrifugation technique and sequential chemical extraction method, suppression subtractive hybridization , RAPD were used in this thesis to study the mechanisms of copper tolerance and accumulation by Commelina communis grown in copper mine deposit which was reported to be a Cu hyperaccumulator, compared with C. communis grown in normal soil. Several aspects were examined, including: difference of copper tolerance and accumulation between C. communis grown in copper mine deposit and that grown in normal soil; difference of growth and nutrient accumunation between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; physiological differences between between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; subcellular distribution and chemical forms of Cu in C. communis; identification of cDNA fragments differentially expressed in C. communis grown in copper mine deposit; genetic diversity and copper tolerance of C. communis, tolerance mechanisms to copper in C. communis are discussed.

Theenvironmental risk of leachate from landfill with different operation modes depend ontheir accumulation amount rather than their sudden concentrations and fraction.(7)The high SRB metabolism activity and the accumulation of metabolitewere the main reasons of in-situ precipitation phenomenon of Cu~(2+) and Zn~(2+) inlandfill refuse in bioreactor landfill. Heavy metals in bioreactor landfill havemechanism of in-situ immobilization controlling by SRB metabolism. Thepredominant SRB in landfill refuse belongs to Desulfovibrio vulgaris sp.
