It occupys a very important position in the industry for a long time. It is the symbol of the developmental level of the electron industry in an era and updating constantly with the development of scientific technology. As a fixed function and long cycle of research and production, and other shortings, the traditional measuring instruments can not meet the demands of information age. So the large developmental space has been supplied for the new type of measuring instrument virtual of the simple construction of the hardware,software achieving a variety of functions mainly, and improving its proformance continuously with the development of the puter. It is provided with strongly adaptability and causes great concern in the world. Virtual machines pletely changed the traditional definition of equipment from the manufacturer function of the model, but in a small amount of additional hardware on the basis defined by the user equipment functions. Because it relies mainly on the operation of the software, modify or add features, improve performance are very flexible and userfriendly PC hardware and software resources and direct use of PC peripherals and working capabilities. Virtual instrument not only low cost, but also by modifying its software to increase the adaptability, thereby extending its life cycle, is a very good development prospects with the equipment. And traditional instruments, virtual instrument is 江蘇技術(shù)師范學院畢業(yè)設(shè)計說明書 （論文） 第 36 頁 共 37 頁 an efficient, open, easytouse flexible, powerful, costeffective, operational and other obvious advantages of good . Electronic measurement system in the virtual instrument of teaching and research in the application. Colleges and universities in particular, science and engineering school, master measuring instruments and equipment operators to use each student is the basic prerequisite for scientific experiments. Teaching, scientific research requires a large amount of measurement and analysis equipment, especially the experimental teaching, each apparatus must be more than targeted, but some equipment is expensive, so the investment required enormous equipment, it is very difficult to meet in ordinary schools, causing many schools Outdated equipment and lack of phenomena such as outdated, seriously affecting teaching and research. CAI use of educational softwareassisted teaching, can better overe the difficult part. However, because of electronic technology in the teaching of CAI software also small, not strong and functional, interactive, operability and the true extent of poor interface, to narrow the scope, to a certain extent, limited the use of teachers and students of the initiative. If the use of virtual instrument systems, the situation will be quite different. The use of virtual machines will not only save a lot of instruments and equipment for investment, but also can enhance the teaching and research quality and efficiency. Teachers in the classroom can be directly carried out on experimental demonstration of remedial teaching. Such as the mon signal — triangle wave, enter a different frequency, graphics interface changes will show directly. 江蘇技術(shù)師范學院畢業(yè)設(shè)計說明書 （論文） 第 37 頁 共 37 頁 二、外文翻譯稿 關(guān)于虛擬儀器及其示例 電子測量儀器是電子行業(yè)的基礎(chǔ)，它在電子行業(yè)中長期占據(jù)著十分重要的地位，它是一個時代的電子行業(yè)發(fā)展水平的標志，并隨著科學技術(shù)的發(fā)展而不斷地更新變化著。傳統(tǒng)的測量儀器由于功能固定，研制生產(chǎn)周期長等缺點，越來越不能滿足信息時代的要求。這就給一種新型的測量儀器 —— 虛擬儀器提供了極大的發(fā)展空間，由于其硬件結(jié)構(gòu)簡單，以軟件為主實現(xiàn)各種功能，且隨計算機的發(fā)展不斷提高其性能，具有很強的適應(yīng) 性，所以越來越引起世人的高度關(guān)注。 虛擬儀器徹底改變了傳統(tǒng)儀器由生產(chǎn)廠家定義功能的模式，而是在少量附加硬件的基礎(chǔ)上，由用戶定義儀器功能。因為它的運行主要依賴軟件，所以修改或增加功能、改善性能都非常靈活，也便于利用 PC的軟硬件資源和直接使用 PC的外設(shè)和網(wǎng)絡(luò)功能。虛擬儀器不但造價低，而且通過修改軟件可增加它的適應(yīng)性，進而延長它的生命周期，是一種具有很好發(fā)展前景的儀器。與傳統(tǒng)儀器相比，虛擬儀器具有高效、開放、易用靈活、功能強大、性價比高、可操作性好等明顯優(yōu)點 。 電子測量虛擬儀器系統(tǒng) 在教學、科研中的運用 。 高等學校特 別是理工科學校，掌握測量儀器和設(shè)備的操作使用方法是每個學生進行科學實驗基本前提。教學、科研需要大量的測量分析儀器設(shè)備，特別是實驗教學，每種儀器都必須配置多套，而且有的儀器設(shè)備價格昂貴，因此儀器設(shè)備所需投資巨大，一般學校很難滿足，造成許多學校儀器設(shè)備缺乏和過時陳舊等現(xiàn)象，嚴重影響教學科研。運用 CAI教學軟件輔助實驗教學，能較好克服存在的部分困難。但是，由于電子技術(shù)實驗教學方面的 CAI 軟件還很少，而且功能不強，交互性、操作性和界面的真實程度較差，適應(yīng)范圍窄，在一定程度上限制了教師和學生使用的積極性。 如果運用虛 擬儀器系統(tǒng)，情況就大不一樣了。使用虛擬儀器不但可以節(jié)約大量儀器設(shè)備的經(jīng)費投入，而且能夠提高教學科研的質(zhì)量與效率。 教師可直接在課堂上對實驗進行演示，輔助教學。如常用信號 —— 三角波，輸入不同的頻率值，圖形變化直接在界面上顯示出來。
