. Seed quality evaluation . Mechanical damage Three replications of 100 seeds were soaked in 1% sodium hypochlorite solution for 10 min. The seeds with seed coat damage swelled visibly and were counted using a hand lens. The split (%) was obtained by passing 200 g of seed through a round hole sieve. The material that passed through the sieve was termed as ‘‘splits’’ and then weighed (Anonymous, 1985). 豆种质量评估机械损伤经过3遍流程的100颗豆种在1%的漂白液中浸泡10分钟。种子以及种皮的很明显地膨胀损坏可以通过手持透镜观测到。 破裂指数通过200g的种子经4毫米圆洞筛网筛选得到。通过筛网的原料被称作“破裂”然后称重。. Germination test Germination ability was determined according to the Association of Official Seed Analysts (Anonymous, 1981). Three replications of 100 seeds were placed in presoaked germination paper and were then placed in a seed germinator at 251C for 7 days. After 7 days, the percentage of seeds germinating normally was recorded. 发芽力检测发芽能力是按照官方的种子专家学会去定义的。经过3次流程的100颗豆种被放置在发芽试纸上预浸，人后在发芽力检测仪上以251C的温度放置7天。 7天之后， 发芽种子的比例被记录下来。. Seed vigor The seed vigor tests were conducted according to the International Seed Testing Association (ISTA) method (Anonymous, 1985). Sheets of paper towel with 350 seeds were kept in a seed germinator at 251C for 7 days. After 7 days, the lengths of germinated seedlings were measured in centimeters. The vigor index was calculated as vigor index ¼ 1 NX germination ð%Þ seedling length ðcmÞ; where N is the number of seeds that germinated. 种子的活力种子活力的检测是按照国际种子检测协会的步骤操作的。350颗豆种放在纸巾上，在种子发芽力检测仪器内以251C的温度保存7天， 7天之后， 以厘米为单位去测量种芽的长度。活力指数是按照vigor index ¼ 1 NX germination ð%Þ seedling length ðcmÞ; where N is the number of seeds that germinated.（此处由于有乱码， 无法翻译）. Accelerated aging This test was used to predict the storage potential of seed. It combines the stresses caused by high temperature and high humidity to which seed maybe exposed. It is expected that the seed lots which record a higher level of germination in the accelerated aging test can be stored for a longer period than others. Two replications of 50 seeds were kept in perforated plastic boxes. These boxes were kept at 401C and at 100% relative humidity(r :h:) for 96 h. The germination of these lots was recorded as outlined by the ISTA (Anonymous, 1985). 加速老化这个检测是用作预告种子的储存潜力的。 它包括也许种子露天放置时，由高温度和高湿度造成的作用。人们预计在发芽力检测中有高记录的那批种子能够在加速老化测验中比其它的种子储存的更久。经过2次流程的50颗种子保存在穿孔的盒子当中。这些盒子被放置在401C温度及100%相对湿度中96个小时。这批的发芽力被ISTA作为要点记录下来。. Determination of moisture content The standard oven method outlined by the ISTA (Anonymous, 1985) was employed. Three replications of 10 g seed were kept in a hot air oven at 1021C for 24 h. At the end of this period, the samples were transferred to a desiccator for cooling. The samples were then weighed and moisture content calculated on a dry mass basis. 含水量的定义ISTA大纲中的标准加热程序被引用到这里。经过3次流程的10g豆种被保存在干烤箱中以1021C的温度放置24小时。 在检测最后， 样品被转移到干燥器中冷却。然后样品称重，并计算含水量，按照折干计算。. Evaluation of damage due to free-fall To determine the effect of height of fall on the seed quality, three replications of 100 seeds, drawn from each treatment, were dropped from a height of , , , or on to a cement floor or a galvanized iron floor. The dropped seeds were tested for germination and vigor as before. . Statistical analysis of data The data collected during the experiments were analyzed using ANOVA (Anonymous, 1992) to study the effects of m:c:; process stages and heights of free-fall on the parameters of seed quality. The differences in means were examined using the Tukey test of 由自由下落造成损失的评估为了确定下落高度对种子质量造成的影响， 经过3遍流程的100颗种子， 分别从， ， ， 米处下落到水泥地或者镀锌铁板上，象以前一样，下落的种子被检测种子发芽力以及活力。数据统计分析使用ANOVA分析了在实验当中所收集的数据，研究了含水量，加工平台以及自由下落的高度参数在种子质量方面的影响。检测方式的差异已被Tukey test of significance.验证。

ADesignfor1480PlanishingMill(注：PinchPassmill,TemperMill也都是平整机，可根据专业实际任选一个)Abstract:Alongwitharapiddevelopmentofthenationaleconomy,

中国是世界上机械发展最早的国家之一。中国的机械工程技术不但历史悠久，而且成就十分辉煌，不仅对中国的物质文化和社会经济的发展起到了重要的促进作用，而且对世界技术文明的进步做出了重大贡献.传统机械方面，我国在很长一段时期内都领先于世界。到了近代由于特别是从18世纪初到19世纪40年代，由于经济社会等诸多原因，我国的机械行业发展停滞不前，在这100多年的时间里正是西方资产阶级政治革命和产业革命时期，机械科学技术飞速发展，远远超过了中国的水平。这样，中国机械的发展水平与西方的差距急剧拉大，到十九世纪中期已经落后西方一百多年。新中国建立后特别是近三十年来，我国的机械科学技术发展速度很快。向机械产品大型化，精密化、自动化和成套化的趋势发展。在有些方面已经达到或超过了世界先进水平。总的来说，就目前而言中国机械科学技术的成就是巨大的，发展速度之快，水平之高也是前所未有的。这一时期还没有结束，我国的机械科学技术还将向更高的水平发展。只要我们能够采取正确的方针、政策、用好科技发展规律并勇于创新，我国的机械工业和机械科技一定能够振兴，重新引领世界机械工业发展潮流。就小型夯实机械而言：上世纪60年代以前，我国小型夯实机械非常缺乏，很多小型场地的夯实基本上采用人工夯实。上世纪60年代初期，长沙建设机械研究所与北京建筑工程学院等单位合作，在群众性技术革新成果的基础上总结发明了具有中国特色的蛙式夯实机，1962年获国家科技发明奖。蛙式夯实机结构简单，维修、使用方便，很快成为我国60年代夯实机械的主导产品。据不完全统计蛙式夯实机累计产量达到50000多台，在我国经济建设中发挥了重要作用。70年代以后，蛙式夯实机逐渐被性能更先进的振动冲击夯和振动平板夯所替代，目前蛙式夯实机已经很少，基本被淘汰。1964年，长沙建设机械研究所开发了HB120型内燃式夯实机，开始由上海工程机械厂生产，后来主要由津市洞庭工程机械厂生产，年产量200台左右。80年代，内燃式夯实机产品质量有较大提高，曾出口东南亚和非洲地区。90年代以后，内燃式夯实机产销售量也在逐渐减少，目前只有少数小型民营企业生产。1977年，长沙建设机械研究所和柳州市建筑机械厂开发了我国第一台HZR250型和HZR70型振动平板夯，这两种产品分别于1979 年和1982年通过了由建设部组织的鉴定。随后义乌建筑机械厂、四平建筑机械厂、安阳振动器厂、津市洞庭工程机械厂等多家企业都开始生产振动平板夯。1986年长沙建设机械研究所又开发了较大的HZR450型振动平板夯。上世纪90年代以后，振动平板夯在我国有了较快的发展，产品品种、规格和生产企业增多，国外的振动平板夯陆续进入中国市场。1983年，长沙建设机械研究所和湖北振动器厂联合开发了我国第一台HZR70型振动冲击夯，1984年通过了由建设部组织的鉴定，1985年获建设部科技进步三等奖。由于振动冲击夯具有压实效果好、生产率高、体积和重量小、轻便灵活等突出特点，深受用户欢迎，得到了迅速的推广使用，并很快发展到资江机器厂、新乡第三机床厂和津市洞庭工程机械厂等几十家企业生产。振动冲击夯虽然比振动平板夯开发晚，但发展速度、产销量和使用广泛性比振动平板夯大得多，目前已成为我国夯实机械中产销量最大的主导产品。上世纪90年代以后，国外的振动平板夯陆续进入中国市场。振动冲击夯和振动平板夯在我国的成功开发，不仅为我国建设施工部门提供了性能先进的夯实机械，取得了良好的经济效益和社会效益，而且使我国夯实机械技术向前跨进了一大步，缩短了与世界先进水平的差距，促进了我国压实机械的发展。就机械加工而言：热加工 铸造 据考古发现，在北京平谷、昌平、房山等处曾出土了公元前16世纪(商代)的青铜礼器。 明永乐年间(1403～1424年)，北京制造出享誉世界的明永乐大铜钟(吨)和钟楼大铜钟(63吨)及铁钟(25吨)，采用分炉熔化、地坑造型和陶范法铸造。 20世纪50年代以前，北京在铸造上采用粘土砂手工造型。1955年，北京第一机床厂开始采用漏模造型、双面模型型板及铁型板和标准砂箱造型。1965年，开始采用塑料模型。 1980 年，北京市机电研究院与北京玛钢厂研制成功工频无芯塞杆底注式保温浇注电炉。1982年，该院与北京机床铸造二厂研究成功冲天炉风口吹氧技术。 1985～1988年，北京机床研究所试验成功浮动端面密封环的压力铸造工艺。 锻压 1959年，北京第二通用机械厂(后改名北京重型机器厂)建成2500吨水压机。1971年，该厂制造出6000吨水压机，这是当时北京最大的锻压设备。 1968～1979年，北京起重机器厂先后采用300吨油压机和2000吨油压机制造出起重机吊臂和大型覆盖件。 80年代，北京市机电研究院和北京市模具中心研制出一系列高精度多工位冲裁模具，接近或达到进口模具水平，改变了北京精密冲裁模具依赖进口的局面。 热处理 1949年前，北京已采用电炉、盐溶炉、热电偶等手段进行零件退火、回火、淬火、正火、调质、渗碳等热处理。 1956年，北京第一机床厂开始采用高频感应淬火。1961年，北京第二机床厂开始采用气体氮化淬火。1969年，北京量具刃具厂开始采用光亮淬火。 1978年，北京机床研究所研究完成机床导轨表面接触淬火工艺及设备、淬火质量检查技术条件的研究。1979年，铁道科学研究院和中国科学院力学研究所等合作完成大功率柴油机缸套表面的激光改性处理的研究。 1979年，北京市机电研究院研制成功千瓦级二氧化碳激光器，并于80年代初分别应用于汽缸套和邮票印刷设备的激光热处理。其中，清华大学、北京市机电研究院、北京邮票厂共同完成邮票厂七色机打孔器表面激光强化研究。 1984～1990年，北京市热处理研究所研究成功真空热处理、气体渗碳微机控制技术(与北京航空航天大学合作)、稀土软氮化、粉末冶金制品表面强化、煤油加甲醇小滴量法微机可控渗碳、固体渗硼、渗碳过程微机辅助工艺设计及跟踪控制系统等热处理新技术，并应用于生产。 焊接与切割 1949年，北京已有气焊、电弧焊及氧乙炔火焰切割等手工作业。 1963年，北京金属结构厂与一机部机械科学研究院合作开发出钨极氩弧焊，并实现了氮气等离子切割不锈钢。1964年，用直流钨极氩弧焊及焊丝合金化技术解决了核工业用倾斜式电解糟纯镍焊接。 1966年，北京金属结构厂开发出了使被焊球体旋转的埋弧自动焊。1968年，该厂开始以液化石油气代替乙炔切割。 80年代初，清华大学发明了新型MIG焊接电弧控制法，在控制电弧技术上取得突破。 80年代初，北京城建设计院等完成液化石油气移动式气压焊轨技术的研究和应用。 1990年，北京金属结构厂开始采用数控精密切割和具有光电跟踪及数控寻踪读入自动编程的大功率等离子切割技术。可见，我国机械发展在近代发展其迅速。China is the world's first national machinery development. Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred the founding of new China, especially in the past 30 years, our country's mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical small ramming machinery:In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial 1960s, changsha construction machinery institute and Beijing architectural engineering institute, etc., the technical innovation achievements in mass on the basis of summing up Chinese characteristic invented the breaststroke ramming machine, 1962 exceeded national science and technology. The breaststroke ramming machine structure is simple, easy to use and maintenance in 1960s, soon became the dominant products to consolidate machinery. According to not complete count breaststroke tamp cumulative yield reached more than 50,000 machine, in the economic development of our country has played an important role. Since 1970's, the breaststroke ramming machine was gradually more advanced performance of vibration shock ram and vibrating plate ram, now replaced by laying machine has rarely breaststroke, basically be 1964, changsha construction machinery institute HB120 developed movable type, type of Shanghai began laying machine, engineering machine production mainly by tianjin municipal later, annual production engineering machinery dongting about 200. In the 1980s, movable type ramming machine product quality has increased greatly, have exported to southeast Asia and Africa. Since 1990s, internal-combustion type ramming machine production sales, and gradually decreased in only a few small private enterprise 1977, changsha construction machinery factory buildings and developed in liuzhou HZR250 type and the HZR70 type vibrating plate ram, these two kinds of products in 1979 and 1982 passed by the ministry of construction of the organization.

毕业论文外文翻译：将外文参考文献翻译成中文版本。

翻译要求：

1、选定外文文献后先给指导老师看，得到老师的确认通过后方可翻译。

2、选择外文翻译时一定选择外国作者写的文章，可从学校中知网或者外文数据库下载。

3、外文翻译字数要求3000字以上，从外文文章起始处开始翻译，不允许从文章中间部分开始翻译，翻译必须结束于文章的一个大段落。

参考文献是在学术研究过程中，对某一著作或论文的整体的参考或借鉴。征引过的文献在注释中已注明,不再出现于文后参考文献中。外文参考文献就是指论文是引用的文献原文是国外的，并非中国的。

原文就是指原作品,原件，即作者所写作品所用的语言。如莎士比亚的《罗密欧与朱丽叶》原文是英语。

译文就是翻译过来的文字，如在中国也可以找到莎士比亚《罗密欧与朱丽叶》的中文版本，这个中文版本就称为译文。

主要标准

翻译是语际交流过程中沟通不同语言的桥梁。一般来说，翻译的标准主要有两条：忠实和通顺。

忠实

是指忠实于原文所要传递的信息，也就是说，把原文的信息完整并且准确地表达出来，使译文读者得到的信息与原文读者得到的信息大致相同。

通顺

是指译文规范、明白易懂，没有文理不通、结构混乱、逻辑不清的现象。

实践产生理论，欧美许多国家的翻译理论是五花八门的。从大的方面来看，可以分为两大派：一派是翻译可能论，一派是翻译不可能论。其实，完完全全百分之百的可能是没有的，完完全全百分之百的不可能也是没有的。

世界上一切翻译活动都是在这两个极端之间进行的。欧洲许多著名的人物，比如马丁·路德、M.阿诺德、.纽曼、.波斯特加特、H.白洛克、.诺克斯、V.那巴可夫等等，都对翻译提出了自己的理论。据《开塞尔世界文学百科全书》的意见，这些理论中有些是刚愎自用的。
