外文翻译-机械密封的性能及新型技术改造

ture, working condition is difficult todo it. In order to reveal the mechanical seal related laws, improve the reliability of parameters of mechanical seal face test and research is the key. Special properties of nanomaterials is helpful to improve the lubrication condition between the mechanical seal face, development of nano-materials mechanical seal mechanical seal research and 8 application of nano rinses will be short-term goals. With the improvement of the experience and the development of technology, mechanical seal will be more and more mature, step by step towards zero leakage, long-term stable operation. 9 指导教师评语外文翻译成绩: 指导教师签字: 年月日注: 1.指导教师对译文进行评阅时应注意以下几个方面:①翻译的外文文献与毕业设计(论文)的主题是否高度相关,并作为外文参考文献列入毕业设计(论文)的参考文献;②翻译的外文文献字数是否达到规定数量( 3 000 字以上);③译文语言是否准确、通顺、具有参考价值。 2.外文原文应以附件的方式置于译文之后。
