Computer network virus and precautionsWith the new network technology and application of the continuous rapid development of the computer network should Use of becoming increasingly widespread, the role played by the increasingly important computer networks and human More inseparable from the lives of the community's reliance on them will keep growing. With With the continuous development of computer technology, the virus has become increasingly complex and senior, the new generation of Computer viruses make full use of certain commonly used operating systems and application software for protection of the weak low Spots have rampant in recent years as the popularity of the Internet in the world, will be attached document containing the virus The situation in the mail has been increasing spread of the virus through the Internet, making the spread of the virus speed Sharp also increased, by an ever-increasing scope of the infection. Therefore, the protection of the security of computer networks will be Will become increasingly important. A computer virus The definition of computer virus computer virus (Computer Virus) in the "people's republic of China The computer information system security protection regulations "which has been clearly defined, the virus" refers to the preparation or Computer program inserted in the damage or destruction of computer data functions, affecting computer use Self-replication and can a group of computer instructions, or code. " Second, network virus With the development of network and the Internet, a wider spread, the greater New harm The virus emerged This is the Internet virus. The virus is an emerging concept in the traditional The virus was not classified network virus this concept, because the development of networks, the traditional virus The network also has a number of characteristics. Today's Internet virus is a broad notion of a As as long as it is carried out using the Internet to spread destruction can be known as network viruses, such as: "Love the back door", "Panda burning incense." Third, network virus and the distinction between computer virus The original common computer virus is nothing more than the devastating formatted hard drive, delete system With the users documents, databases, etc. destruction. The mode of transmission is through nothing but also by virus infection Mutual copy of the software, carrying the virus, such as the use of pirated optical discs, such as infection disk systems The pilot virus and infected executable file virus, in addition to a network virus These are the common characteristics of the virus, but also steal users with remote data, remote control of the other side Computers and other damaged properties, such as Trojan and consumption of funding the operation of the network computer Source collapse of the network server worm. Fourth, the network against virus Network destructive virus, will directly affect the work of the network, ranging from lowering speed video Ring for the efficiency of the network, while in the collapse, undermining the server information to a multi-year work destroyed Dan. Because viruses and other network annually fraud led to economic losses of over 16 billion yuan, But this figure is constantly rising year by year. The next few years, the size of the market will reach Security 60 billion yuan. One antivirus software experts pointed out: "Network avian flu virus even more." Such as: "Xiong Cat burning incense "In addition to virus infection through the web site users, the latest virus also through QQ Loopholes in propagating itself through file-sharing networks, the default sharing, weak password systems, U disk and windows Forms bottom of the top mobile hard drives, and other means of communication. While LAN once a computer machine For infection, it can spread through the entire network instant, or even within a very short period of time can be infected Thousands of computers, can lead to serious networks. Symptoms of poisoning in the performance of computers There are enforceable. Exe files have become a strange pattern, the pattern shown as "Panda Burning incense, "and then System blue screen, restart the frequent, hard drive data destruction, serious entire company All computer LAN will all poisoning. "Panda burning incense," only more than half a month, a few varieties have high Of more than 50, and the number of its users infected constantly expanding. Makes infected, "Panda burn incense" disease The personal drug users has been as high as several million people infected with a few more corporate users is rising exponentially. Network More on the computer network the greater the harm caused by the virus. V. network transmission of the virus Features 1. Infection fast: single machine environment, the virus can only be passed from one computer diskette To another, and in the network can be adopted by the rapid spread of network communication mechanism. According to measurement Set against a typical PC network use in normal circumstances, once a computer workstation sick Drugs, and will be online within 10 minutes in the several hundreds of all infected computers. 2. Proliferation of a wide range: in the network due to the spread of the virus very quickly and spread to encompass a large area, not only the rapid transmission of all LAN computer, but also through remote workstations virus in一瞬Inter spread to thousands of miles away. 3. Dissemination in the form of complex and varied: computer viruses in general through the network " Station server workstation "channels of communication, but in the form of complex and diverse communication. 4. Difficult to completely wipe: the standalone computer virus carriers sometimes can be deleted documents Or low-level formatted drives, and other measures to eliminate the virus completely, and the network once a computer work Clean stations failed to disinfect the entire network can be re-infected by the virus, or even just completed removal The work of a workstation is likely to be on-line by another workstation virus infection. Therefore, Only workstations in addition to killing viruses, and can not solve the virus harm to the network is. 6, the type of network virus As the network increasingly developed, the type of network virus has been increasing, generally summed up as The following categories: 1. Worm It is the use of the transmission mechanism of replication and dissemination network, the mode of transmission is through the network And e-mail, the prefix is Worm. For example, in recent years the great harm "Nimda" virus is Demodex A worm virus. The virus used Microsoft's Windows operating system, computer flu With this virus, will continue to automatically dial-up Internet access and use information in the document or the address Sharing network spreads, and ultimately undermine the most important user data. 2. Macro Virus Hong virus is a Storage in the document or template in the Acer computer virus. The prefix Macro, once open such documents, which Acer will be implemented, then the virus would Acer Been enabled transferred to the computer, and in the presence of the Normal template. From then on, all since The document will be kept moving "infection" that the Hong virus, and if other users opened the flu Documents with the virus, the Hong virus will be transferred to his computer. 3. Destructive procedures virus The prefix destructive virus program is: Harm. The characteristics of this virus is a good in itself Look at the user clicks on icons to temptation, when the user clicks on the virus, the virus will direct users Computer generated destruction. If C formatted disk (Harm.formatC.f), the killer orders (Harm. Command.Killer). 4. System virus The prefix system for the virus: Win32, PE, Win95, W32, W95, and so on. These viruses The characteristics of the general public can be infected with the windows operating system *. exe and *. dll file, And through these documents for dissemination. If the CIH virus. 5. Backdoor virus Backdoor virus prefix is Backdoor. The total of such virus through network - Sowing, opened the back door to the system to the user and potential safety problems. 6. Bundling machine virus Bundled-virus prefix is: Binder. The characteristics of this virus is the virus writers will use Specific procedures will be bundled with a number of applications such as QQ, IE bundled up on the surface It is normal to see the paper, when users run these bundled virus, will run these applications on the surface Procedures, and then tied to the operation of hidden virus, which caused harm to the user. Such as: baled Tied QQ (Binder.QQPass.QQBin), the system killer (Binder.killsys). 7. Script virus The virus is usually JavaScript scripting code prepared by the malicious code, prefix is usually Spript, with the general nature of advertising, will modify your IE Home, modify registry, and other information, Computer user inconvenience caused. 8. Planting procedures virus virus This virus is of the public will run from the in vivo release of one or several new Under the virus to the system directory, by the release of a new virus damage. If the glaciers are sowing (Dropper.BingHe2.2C), MSN striker (Dropper.Worm.Smibag). 9. Joke virus The prefix is the virus joke: Joke. Also called prank virus. The characteristics of this virus is itself a nice user clicks on icons to temptation, When the user clicks of this virus, the virus will be made to disrupt the operation scare users, in fact The virus did not destroy any computer user. Such as: ghost (Joke.Girlghost) virus. 10. Trojan hacking virus Trojan its prefix is: Trojan, hackers virus prefix General for Hack. Public special Sex is through the network or system loopholes into the user's system and hidden, and then leaked to the outside world User information, hackers virus there is a visual interface to the user's computer remotely Control. Trojans, hackers often paired virus emerging, Trojan horse virus responsible for the invasive power users Brain, and hackers virus will be passed to the Trojan horse virus control. . General Trojan such as QQ News tail Trojan Trojan.QQ3344, there are big Trojan.LMir.PSW.60. Virus Form A PSW or anything like PWD general said that the virus has stolen password function, If some hacker programs, such as network枭雄Hack.Nether.Client. 7, the mode of transmission and network anti-virus Through the above, we can see that e-mail viruses spread Click homepage, users download, Others implant, implant, and other loopholes through five computer transmission, so long as holding these five A thoroughfare, we will be able to live better anti-virus network. 计算机网络病毒与防范随着各种新的网络技术的不断应用和迅速发展, 计算机网络的应用范围变得越来越广泛, 所起的作用越来越重要, 计算机网络与人类的生活更加密不可分, 社会对其的依赖程度也会随之不断增长。而随着计算机技术的不断发展, 病毒也变得越来越复杂和高级, 新一代的计算机病毒充分利用某些常用操作系统与应用软件的低防护性的弱点不断肆虐, 最近几年随着因特网在全球的普及, 将含病毒文件附加在邮件中的情况不断增多, 通过网络传播病毒, 使得病毒的扩散速度也急骤提高, 受感染的范围越来越广。因此, 计算机网络的安全保护将会变得越来越重要。一、计算机病毒计算机病毒的定义计算机病毒(Computer Virus)在《中华人民共和国计算机信息系统安全保护条例》中被明确定义, 病毒“指编制或者在计算机程序中插入的破坏计算机功能或者破坏数据, 影响计算机使用并且能够自我复制的一组计算机指令或者程序代码”。二、网络病毒随着网络和Internet 的发展,一个传播范围更广,危害更大的新型病毒应运而生.这就是网络病毒。网络病毒是一个新兴的概念, 在传统的病毒分类里没有网络病毒这个概念, 由于网络的发展, 传统的病毒也就具有了一些网络的特性。如今的网络病毒是一个广义的概念, 一般只要是利用网络来进行传播、破坏的都可以被称为网络病毒, 如:“爱情后门”、“熊猫烧香”等。三、网络病毒与计算机病毒的区别原先常见的计算机病毒的破坏性无非就是格式化硬盘, 删除系统与用户文件、破坏数据库等等。而传播途径也无非是通过遭病毒感染的软件的互相拷贝, 携带病毒的盗版光盘的使用等, 如感染磁盘系统区的引导型病毒和感染可执行文件的文件型病毒, 而网络病毒除了具有普通病毒的这些特性外, 还具有远端窃取用户数据、远端控制对方计算机等破坏特性, 比如特洛伊木马病毒和消耗网络计算机的运行资源, 拖垮网络服务器的蠕虫病毒。四、网络病毒的危害网络上病毒破坏性大, 将直接影响网络的工作, 轻则降低速度, 影响工作效率, 重则使网络崩溃, 破坏服务器信息, 使多年工作毁于一旦。每年由于病毒等网络欺诈行为导致的经济损失高达160 亿多元,而且这个数字逐年还在不断地攀升。未来几年, 安防市场规模将达到600 亿元。一位杀毒软件专家指出: “网络病毒更甚于禽流感”。如: “熊猫烧香”除了通过网站带毒感染用户之外, 此病毒还会通过QQ 最新漏洞传播自身, 通过网络文件共享、默认共享、系统弱口令、U 盘及窗体顶端窗体底端移动硬盘等多种途径传播。而局域网中只要有一台机器感染, 就可以瞬间传遍整个网络, 甚至在极短时间之内就可以感染几千台计算机, 严重时可以导致网络瘫痪。中毒症状表现为电脑中所有可执行的.exe 文件都变成了一种怪异的图案, 该图案显示为“熊猫烧香”, 继而系统蓝屏、频繁重启、硬盘数据被破坏等, 严重的整个公司局域网内所有电脑会全部中毒。“熊猫烧香”仅半个多月, 变种数已高达50 多个, 并且其感染用户的数量不断扩大。使得感染“熊猫烧香”病毒的个人用户已经高达几百万, 企业用户感染数更是成倍上升。网络上的计算机越多, 网络病毒造成的危害越大。五、网络病毒传播特点1.感染速度快: 在单机环境下, 病毒只能通过软盘从一台计算机带到另一台, 而在网络中则可以通过网络通讯机制迅速扩散。根据测定, 针对一台典型的PC 网络在正常使用情况, 只要有一台工作站有病毒, 就可在几十分钟内将网上的数百台计算机全部感染。2.扩散面广: 由于病毒在网络中扩散非常快, 扩散范围很大, 不但能迅速传染局域网内所有计算机, 还能通过远程工作站将病毒在一瞬间传播到千里之外。3.传播的形式复杂多样: 计算机病毒在网络上一般是通过“工作站服务器工作站”的途径进行传播的, 但传播的形式复杂多样。4.难于彻底清除: 单机上的计算机病毒有时可通过删除带毒文件或低级格式化硬盘等措施将病毒彻底清除, 而网络中只要有一台工作站未能消毒干净就可使整个网络重新被病毒感染, 甚至刚刚完成清除工作的一台工作站就有可能被网上另一台带毒工作站所感染。因此,仅对工作站进行病毒杀除, 并不能解决病毒对网络的危害。六、网络病毒的类型由于网络越来越发达, 网络病毒的种类也越来越多, 大体归纳为以下几类:1.蠕虫病毒它的传染机理是利用网络进行复制和传播, 传染途径是通过网络和电子邮件,前缀是Worm。比如近年危害很大的“尼姆达”病毒就是蠕虫病毒的一种。这一病毒利用了微软视窗操作系统的漏洞, 计算机感染这一病毒后, 会不断自动拨号上网, 并利用文件中的地址信息或者网络共享进行传播, 最终破坏用户的大部分重要数据。2.宏病毒宏病毒是一种寄存在文档或模板的宏中的计算机病毒。前缀是Macro, 一旦打开这样的文档, 其中的宏就会被执行, 于是宏病毒就会被激活, 转移到计算机上, 并驻留在Normal 模板上。从此以后, 所有自动保存的文档都会“感染”上这种宏病毒, 而且如果其他用户打开了感染病毒的文档, 宏病毒又会转移到他的计算机上。3.破坏性程序病毒破坏性程序病毒的前缀是: Harm。这类病毒的特性是本身具有好看的图标来诱惑用户点击, 当用户点击病毒时, 病毒便会直接对用户计算机产生破坏。如格式化C 盘(Harm.formatC.f) 、杀手命令(Harm.Command.Killer) 等。4.系统病毒系统病毒的前缀为:Win32、PE、Win95、W32、W95 等。这些病毒的一般公有的特性是可以感染windows 操作系统的*.exe 和*.dll 文件,并通过这些文件进行传播。如CIH 病毒。5.后门病毒后门病毒的前缀是Backdoor。该类病毒的共有特性是通过网络传播, 给系统开后门, 给用户带来安全隐患。6.捆绑机病毒捆绑机病毒的前缀是: Binder。这类病毒的特性是病毒作者会使用特定的捆绑程序将病毒与一些应用程序如QQ、IE 捆绑起来, 表面上看是正常文件, 当用户运行这些捆绑病毒时, 会表面上运行这些应用程序, 然后隐藏运行捆绑在一起的病毒, 从而给用户造成危害。如: 捆绑QQ(Binder.QQPass.QQBin) 、系统杀手(Binder.killsys) 等。7.脚本病毒脚本病毒通常是JavaScript 代码编写的恶意代码, 前缀是通常为Spript, 一般带有广告性质, 会修改您的IE 首页、修改注册表等信息,造成用户使用计算机不方便。8.病毒种植程序病毒这类病毒的公有特性是运行时会从体内释放出一个或几个新的病毒到系统目录下, 由释放出来的新病毒产生破坏。如冰河播种者(Dropper.BingHe2.2C) 、MSN 射手(Dropper.Worm.Smibag)等。9.玩笑病毒玩笑病毒的前缀是: Joke。也称恶作剧病毒。这类病毒的特性是本身具有好看的图标来诱惑用户点击,当用户点击这类病毒时, 病毒会做出各种破坏操作来吓唬用户, 其实病毒并没有对用户电脑进行任何破坏。如: 女鬼( Joke.Girlghost) 病毒。10.木马黑客病毒木马病毒其前缀是: Trojan, 黑客病毒前缀名一般为Hack。公有特性是通过网络或者系统漏洞进入用户的系统并隐藏, 然后向外界泄露用户信息, 黑客病毒则有一个可视的界面, 能对用户的电脑进行远程控制。木马、黑客病毒往往是成对出现的, 木马病毒负责侵入用户的电脑, 而黑客病毒则会通过该木马病毒来进行控制。。一般的木马如QQ消息尾巴木马Trojan.QQ3344, 还有大Trojan.LMir.PSW.60。病毒名中有PSW或者什么PWD 之类的一般表示这个病毒有盗取密码的功能,一些黑客程序如网络枭雄Hack.Nether.Client 等。
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(46.5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 years.After 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 industry.Just small ramming machinery:In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming.Early 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 eliminated.In 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 production.In 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. Then yiwu building construction machinery factory, siping, anyang vibrators factory, tianjin municipal engineering machinery dongting and other enterprises have started producing vibrating plate ram. In 1986, changsha construction machinery research and develop a larger HZR450 type of vibrating plate ram. Since 1990s, vibrating plate ram in our country has developed very quickly, varieties of products, specifications and increase production enterprises, foreign vibrating plate ram gradually to enter the Chinese market.In 1983, changsha construction machinery institute and the joint development of hubei vibration in the first HZR70 type vibration shock ramming, 1984, passed by the ministry of construction, organization construction technology progress in 1985 won prizes. Due to the vibration impact compaction result has good ramming, productivity, high volume and weight of small, lightweight flexible outstanding characteristics, deeply user etc, obtained a rapid promotion, and soon ZiJiang development to the factory, xinxiang municipal engineering machine tool plant and tianjin dozens of dongting production factory etc. Vibration shock ramming although than vibrating plate ram, but later development speed of development, production and use of extensive than vibrating plate ram, has become the largest in China in the ramming machinery products. Since 1990s, foreign vibrating plate ram gradually to enter the Chinese market.Vibration shock ramming and vibrating plate ram the successful development in our country, not only for our construction department provides advanced performance of mechanical, laying have achieved good economic benefit and social benefit, and make our ramming mechanical technology into a big step forward, shorten the gap with the advanced world level, promoting the development of compaction machine.The mechanical processing:According to the archaeological discovery, hot-working casting in Beijing pinggu, changping and so have proved that the 16th century BC shang dynasty (bronze objects. Ming yongle (1403-1424 years), Beijing produce world-renowned Ming yongle great 3-ton bell made (46.5 tons) and tower (63 tons of great 3-ton bell made of iron clock (25) and the furnace of melting, pit TaoFan model and method of casting. In the 1950s, Beijing based on clay sand castings in manual.
