The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

The surface appearance and hygroscopicity of ADN after coating were analyzed by SEM and weighing method. Results show that a kind of floccule of PU is formed on the surface of ADN, which makes the hygroscopicity of ADN after coating less than that before coating evidently. When coated ADN is exposed in the atmosphere for 30 days with the RH less than 60%, the hygroscopicity of coated ADN is only 0.136% and does not increase with the increasing of exposure time.

It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.

研究结果表明，Pd-Co/活性炭催化剂是目标转移加氢反应的最适宜催化剂，Pd-Co/γ-Al203效果也较好，而硅胶和硅藻土由于表面酸性较强，容易造成生成聚合物而堵塞催化剂微孔、使催化剂迅速失活；此外，添加Bi、Ce、Cu等助剂时对活性并无改善作用，而添加La和Ba助剂时可使Pd的催化活性有所提高，效果最好的是Co助剂，尤其是先浸渍Co的Pd-Co/C催化剂，原因是Co占据了活性炭的微孔、覆盖了某些对目标反应不利的官能团，使其活性和选择性都有较大幅度的提高。

Antibacterial function of body wall was conducted by the following way: microorganism was directly resisted through the change of cuticle, such as incrassation of up-cuticle protuberance and increasing length of micro-floccus in the up-cuticle dissociation surface; exudation function of large granular orthochromatic mucous cells and reticulation mucous cells in the epidermis could be enhanced when the Eisenia fetida was induced by E. coli. Moreover, the mucus that contained compound substance of mucopolysaccharide and protein could make the bactericidal function or dilute the microorganism on the surface of earthworm, which could protect earthworm from invasion of microorganism; the content of neutral mucopolysaccharide of antibacterial function could be increased according with the exudation increment of small granular proteinaceous cells in the epidermis, which could resist bacteria invading into the epidermis of earthworm.

结果表明：蚯蚓的体壁主要是通过以下途径来抗细菌的侵袭：一是通过角质层的变化(如上胶层突起的增厚、上角层游离面中微绒毛的变长等)直接抵抗微生物的入侵；二是增加表皮中大颗粒粘液细胞和网状细胞的分泌功能，分泌出大量含有粘多糖蛋白液体复合物的粘液，在蚯蚓体表对细菌进行稀释或者起到直接杀菌的作用；三是通过增加小颗粒蛋白细胞的分泌作用，在蚯蚓的表皮中分泌出更多的抵抗疾病的中性粘多糖，从而抵抗进入蚯蚓体表内的细菌。
