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.

With this method the copper plating graphite powder was made up in 50% copper content .The silver- copper plating graphite composite was prepared while the silver- copper-graphite composite and the silver-graphite composite were also made up together .The mechanical and electric characteristics of the three kinds of composites were tested and it was found that the copper plating graphite powder can only optimize the properties of the silver matrix composite under the high content of the graphite ,the conductivity and the mechanical property was improved and the material could take higher current in the same carbon content .At 20% carbon content, the resistivity of Ag-graphite composite was 1.67 times as high as that of silver- copper plating graphite composite, the resistivity of Ag-Cu-graphite composite was 3.23 times as high as that of silver- copper plating graphite composite. The bending strength of silver-copper plating graphite composite was 2.17 times as high as that of silver- copper-graphite composite, and the bending strength was 2.11 times as high as that of silver- copper-graphite composite. The wearability of silver- copper plating graphite composite was also enhanced greatly at high carbon content.

利用该方法制备了50%铜含量的镀铜石墨粉，然后进一步制备了一系列相同碳含量的银-石墨复合材料、银-铜-石墨复合材料、银-镀铜石墨复合材料，对三种材料的机械、电气性能进行了综合对比，发现在低碳含量时镀铜石墨粉不能改善复合材料的上述主要性能，而在中高碳含量时则能明显优化复合材料的整体性能，提高了复合材料的电导率，使复合材料在中高碳含量时既具有较高的耐磨性同时也能负载较大的电流，复合材料的机械性能也因镀铜石墨粉的加入而大幅提高，20%碳含量时，银-石墨复合材料的电阻率是银-镀铜石墨复合材料的1.67倍，银-铜-石墨复合材料的电阻率为银-镀铜石墨复合材料的3.23倍，银-镀铜石墨复合材料抗弯强度是银-铜-石墨复合材料的2.17倍，是银-石墨复合材料的2.11倍，同时，在实验给定的条件下，中高碳含量时银-镀铜石墨复合材料的机械磨损耐磨性和通电磨损耐磨性都得以显著提高，银-镀铜石墨复合材料在实验时的接触电压降也更为稳定。
