On the basis of previously research, this paper re-probe into the mechanism of electro-chemist mechanical manufacturing process, making the rational technological parameter, and developing the manufacturing equipment. Through a lot of technology tests, get a lot of labratory data, accordingly, researched the surface feature of the electro-chemist manufacturing process, and deeply discussed its influence on the work piece feature. The last result is that: the electro-chemist mechanical manufacturing process can reduce the low-frequency component significantly, but on high-frequency component, it has little influence, having obviously positive pole flat effect. After manufacture, the tip parts on the surface of the work piece is cut off, there is micro "high land" shape, the parameter for surface roughness is reduced a lot, the surface outline of the work piece is negative, the bearing length rate is cliffy. Also the surface quality of the work piece is improved. This can help to avoid changing the shape, improve the feature of rub, gear and reduce the time to suit. This would also ensure the precision and result in a longer work piece life.

在以前研究的基础上，本论文重新探讨了电化学机械复合光整加工工艺的机理，确定了较合理的工艺参数，对电化学机械复合光整加工设备进行了改进，通过工艺实验广泛地搜集了大量实验数据，依据实验数据，多角度地研究了电化学机械复合光整加工的表面形貌特点，并且从理论上深入讨论了电化学机械复合光整加工表面形貌对工件工作性能的影响，最后得出的结论为：电化学机械复合光整加工对工件原始表面的低频成分有较大程度的降低，而对高频成分影响较小，有明显的阳极整平作用，被加工工件表面的尖峰状凸起被去除，工件表面呈现出微观&高原型&，表面轮廓不平度高度特性参数大幅度降低，工件表面轮廓分布集中，且呈负偏态，轮廓偏斜度为负值，轮廓支承长度率曲线陡峭，工件的表面质量得到综合改善，这对提高零件的抗接触变形能力、改善摩擦、磨损性能、降低工件的磨合时间、提高工件的精度保持性、延长工件的寿命均有利。

Methods The compound preparation was administered intragastrically in mice, whose spontaneous activity was observed along with their tolerance of the preparation after long-term administration. The hypnotic effect of the compound was assessed by investigating the changes in the pentobarbital sodium-induced sleeping. The compound was tested for its antiseizure effect in mice with pentetrazole-induced clonic and tonic convulsion. Diazepam was used as the standard control in all experiments.

AFM images revealed that as the sputtering time was prolonged, the film thickness increased, the film became compacter, and the specific area of the film also increased, thus, the release rate of silver ions increased, which led to improved antibacterial properties. EDX test results indicated that increase in film thickness led to increase in silver weight percentage per unit surface, causing improved antibacterial properties. Moreover, when the film thickness was 1 nm, the inhibition percentage of Staphylococcus aureus and Escherichia coli were 100%.

结果表明：随着薄膜厚度的增大，样品抗菌性能提高；溅射时间延长，薄膜厚度增大，膜层的致密性改善，单位面积上的银含量增加，膜层表面积增大，银离子释放几率增大，是提高抗菌性能的主要原因；当纳米结构银薄膜厚度为1 nm时，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到100%。
