科學依據(jù)（包括課題的科學意義；國內(nèi)外研究概況、水平和發(fā)展趨勢；應(yīng)用前景等）
隨著科學技術(shù)的發(fā)展，機電產(chǎn)品日趨精密復雜。產(chǎn)品的精度要求越來越高、更新?lián)Q代的周期也越來越短，從而促進了現(xiàn)代制造業(yè)的發(fā)展。用普通的機床加工精度低，效率低，勞動度大，已經(jīng)無法滿足生產(chǎn)要求，從而一種新型的數(shù)字程序控制的機床應(yīng)運而生。這種機床是一種綜合應(yīng)用了計算機技術(shù)、自動控制技術(shù)、精密測量和機械設(shè)計等新技術(shù)的機電一體化的產(chǎn)品。數(shù)控機床是一種裝有程序控制系統(tǒng)的自動化機床，它對加工精度和自動化都有嚴格的要求。數(shù)控車床上的工位夾緊裝置對于加工的精度有著直接的關(guān)系，以往的機床的工位夾緊裝置使用簡單的機械裝置，在加工時容易產(chǎn)生大的加工誤差。隨著數(shù)控車床自動化程度的提高，使用液壓系統(tǒng)控制這一過程已經(jīng)大大提高了自動化和加工精度。液壓傳動在機械設(shè)備中的應(yīng)用非常廣泛。有的設(shè)備是利用其能傳遞大的動力，且結(jié)構(gòu)簡單、體積小、重量輕的優(yōu)點，如工程機械、礦山機械、冶金機械等；有的設(shè)備是利用它操縱控制方便，能較容易地實現(xiàn)較復雜工作循環(huán)的優(yōu)點，如各類金屬切削機床、輕工機械、運輸機械、軍工機械、各類裝載機等。所以研究液壓系統(tǒng)有很好的應(yīng)用價值和廣闊的前景。我國進入世界貿(mào)易組織之后，對我國的機械行業(yè)是個機遇，更是一個艱難的挑戰(zhàn)。因此作為二十一世紀的主人，我們更應(yīng)該通過作大量的設(shè)計制造和廣泛地使用各種先進的機器，以便能加快我國國民經(jīng)濟的增長速度，加快我國現(xiàn)代化建設(shè)。

英文原文
Machinery, Machina Mechine derived from the Greek and Latin,
Mechanical gear (figure 1) means "clever design", as a general mechanical concept, can be traced back to the Roman period, main is to distinguish and hand tools. Of modern Chinese language the word "Machine" is organization is (Mechanism) of the English and the floorboard of the Machine (the Machine). Mechanical characteristics are: machinery is a combination of physical components. To determine the relative motion of mechanical parts. So the Machine can convert mechanical energy or accomplish useful mechanical work, is the most basic concept in modern mechanical principle, the modern concept of Chinese machinery more derived from the word "Machine" of the Japanese, Japanese machinery should supplies to do the following definition (that is, in accordance with the following three characteristics is called mechanical Machine) :
1, the machinery is a collection of objects, concentration to the various parts are also difficult to deformation.
2, the object must implement the mutual movement, single, regulations.
3, to exert energy into a useful form, or converted into mechanical work effectively.
Mechanism and machine definition is derived from the mechanical engineering, belongs to the most basic concept of modern mechanical principles, mechanical more modern concepts derived from Chinese of the word "machine" in Japanese.
All have certain sports machine and the floorboard of the system. Such as machine tools, tractors, etc.
Mechanical engineering is related to the theoretical basis of natural science and technology,
Mechanical gear (figure 2) combined with the accumulation of technical experience in the production practice, study and solve in the development, design, manufacture, installation, use and repair of all kinds of machinery an applied subject of theoretical and practical problems.
Every development in the field of engineering requirements in mechanical engineering has adapted to the development, need mechanical engineering provides the necessary machinery. Some mechanical invention and improvement, and could lead to new engineering technology and the emergence and development of new industry. Large machinery manufacturing success, for example, led to the establishment of electric power system; The invention of the locomotive led to the rise of railway engineering and railway undertakings; The invention of the internal combustion engines, gas turbines, rocket engines, etc and progress, as well as the successful development of aircraft and spacecraft has led to the rise of aviation and aerospace business; The development of high voltage equipment lead to the success of many new synthetic chemical engineering and so on.
Mechanical engineering is in all respects under the pressure of rising demand for development, at the same time from different disciplines and the advancement of the technology improved and innovative ability.
Machinery is a simple device, it can transfer energy, force from one place to another place.
Mechanical gear (FIG. 3) it can change the shape of the object structures to create new objects. In life, all around us there are thousands of different kinds of machinery in the work for us.
Everyday understanding of mechanical is a mechanical device, which is all kinds of machines and equipment.
From the point of view of mechanical professional: machinery has a very important basic position.
Machinery is a modern society the five factors of production and service (that is, people, money, energy, materials and machinery).
When Marx to industrial society, industrial society, especially in big industrial society, which is machine production machine age.
Whether from life in contact with all kinds of physical devices, such as telephones, electric lights, television, refrigerator, elevator and so on contains the machine, or included in the general machinery, and from the point of production, all kinds of machine tools, automation equipment, aircraft, ships, god five, six, and so on, are short of machinery.
So, machinery is one of the foundations of modern society. If someone say agriculture is the foundation, also understandable, but in modern society, mechanical serve as the basis for the rest of the industry and engineering, it is no exaggeration to think is the big pillar in society.
Any modern industrial and engineering applications require machinery, is the People's Daily life, are increasingly used all kinds of machinery, such as cars, bicycles, watches and clocks, cameras, washing machine, refrigerator, air conditioner, vacuum cleaners, etc.
The first "machine" is defined as the Roman architect vitruvius pollio (Vitruvii) in it
Mechanical gear (figure 4) for building ten book mainly for carrying heavy things work machinery and tools: the difference between "mechanical (machane) and tools (organon) seem to have the following differences between. The machine is most artificial and very big power and effect, such as heavy ballista and grapes press. While the tool is a manipulation of the staff carefully processing, to achieve the purpose of such as were the shape of light range ballista or circular spiral device. Thus, tools and machinery are used in the indispensable thing." The ancient Greek for cylindrical gears. Alexandria, Mr Hiro (Heron of Alexandria) in the 1st century first discussed the basic elements of machinery, mechanical elements considered to be five classes: wheel and shaft, lever, pulley, wedge, spiral. Hiro's discourse reflects the classical mechanical characteristics. BC China has guidelines on the application of complex gear system, the incense burner in the application of the permanent "control level of the bogie and other parts of a cross. "Annotations", said: "the machine, the crossbow tooth; enclosed, the arrow around." Said wen jie zi "explanation of" machine "is" machine, the main mover ", refers to the crossbow.
Mechanical in leipzig, Germany in 1724 and liao poulter (Leopold) is defined as "machines or tools is a kind of artificial device, use it to produce favorable movement; at the same time can't use other ways to save time and power, it can save". British mechanics, Willis (truly illis) in its "agency theory" (The Principle of Mechanism, 1841) give The definition of:
Machinery gear speed reducer "any machine (machine) are made in a variety of different ways of connecting a set of artifacts that make it a component, the component will happen in a certain sport, these artifacts and the initial movement of the components of relative motion relationship depends on the nature of the connections between them." German machinery at le loro (F.R euleaux) in the theory of kinematics (Theoretische Kinematik, Grundzuge einer Theorie
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.

中文原文
機械，源自于希臘語之Mechine及拉丁文Machina，
機械齒輪（圖1）原指“巧妙的設(shè)計”，作為一般性的機械概念，可以追溯到古羅馬時期，主要是為了區(qū)別與手工工具?，F(xiàn)代中文之“機械”一詞為機構(gòu)為英語之（Mechanism）和機器（Machine）的總稱。機械的特征有：機械是一種人為的實物構(gòu)件的組合。機械各部分之間具有確定的相對運動。故機器能轉(zhuǎn)換機械能或完成有用的機械功，是現(xiàn)代機械原理中的最基本的概念，中文機械的現(xiàn)代概念多源自日語之“機械”一詞，日本的機械應(yīng)用品對機械概念做如下定義（即符合下面三個特征稱為機械Machine）：
1、機械是物體的組合，假定力加到其各個部分也難以變形。
2、這些物體必須實現(xiàn)相互的、單一的、規(guī)定的運動。
3、把施加的能量轉(zhuǎn)變?yōu)樽钣杏玫男问?，或轉(zhuǎn)變?yōu)橛行У臋C械功。
機構(gòu)和機器的定義來源于機械工程學，屬于現(xiàn)代機械原理中的最基本的概念，中文機械的現(xiàn)代概念多源自日語之“機械”一詞。
一切具有確定的運動系統(tǒng)的機器和機構(gòu)的總稱。如：機床、拖拉機等。
機械工程就是以有關(guān)的自然科學和技術(shù)科學為理論基礎(chǔ)。
機械齒輪（圖2）結(jié)合在生產(chǎn)實踐中積累的技術(shù)經(jīng)驗，研究和解決在開發(fā)設(shè)計、制造、安裝、運用和修理各種機械中的理論和實際問題的一門應(yīng)用學科。
各個工程領(lǐng)域的發(fā)展都要求機械工程有與之相適應(yīng)的發(fā)展，都需要機械工程提供所必需的機械。某些機械的發(fā)明和完善，又會導致新的工程技術(shù)和新的產(chǎn)業(yè)的出現(xiàn)和發(fā)展。例如大型動力機械的制造成功，促成了電力系統(tǒng)的建立；機車的發(fā)明導致了鐵路工程和鐵路事業(yè)
