【正文】 。 教師可直接在課堂上對實驗進行演示，輔助教學。 如果運用虛 擬儀器系統(tǒng)，情況就大不一樣了。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。 高等學校特 別是理工科學校，掌握測量儀器和設備的操作使用方法是每個學生進行科學實驗基本前提。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 。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的外設和網絡功能。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，由于其硬件結構簡單，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 性，所以越來越引起世人的高度關注。 有人可以僅靠自己的力量獨立的完成一項工作，我的設計在大量資料的指導前提下進行，最后要感謝那些在虛擬儀器等領域有著卓越建樹的專家學者，他們的開拓性工作為后輩提供了高起點，為整個社會的發(fā)展做出了巨大貢獻！ 江蘇技術師范學院畢業(yè)設計說明書 （論文） 第 33 頁 共 37 頁 附錄 附錄一 實物圖 江蘇技術師范學院畢業(yè)設計說明書 （論文） 第 34 頁 共 37 頁 附錄二 元器件清單 元器件名 型號 個數(shù) 雙運放 LM358 1 瓷片電容 1uf 1 可調 電阻 100K 1 可調電阻 47K 1 電阻 10K 3 電阻 20K 1 電阻 1 導線、插針 若干 江蘇技術師范學院畢業(yè)設計說明書 （論文） 第 35 頁 共 37 頁 附錄 三 中英文翻譯 一、 外文原稿 The Virtual Instrument and Its Instance Electronic measuring instruments is the basis of the electron industry. 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 江蘇技術師范學院畢業(yè)設計說明書 （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. 江蘇技術師范學院畢業(yè)設計說明書 （論文） 第 37 頁 共 37 頁 二、外文翻譯稿 關于虛擬儀器及其示例 電子測量儀器是電子行業(yè)的基礎，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，并隨著科學技術的發(fā)展而不斷地更新變化著。通過編程和數(shù)據(jù)采集卡，采集外部的信號，這使我產生了很大的興趣。 在畢業(yè)設計的這一段時間， 首先要感謝我的 畢業(yè)設計 指導老師， 劉素芬 老師一直耐心的指導 ，培養(yǎng) 了 我獨立學習思考的能力，建議 我在原有程序上改進與 創(chuàng)新 。 江蘇技術師范學院畢業(yè)設計說明書 （論文） 第 31 頁 共 37 頁 參考文獻 [1]陳小林 .基于 LabVIEW 的虛擬儀器的設計 [J].溫州師范學院學報， 2021， 25（ 2）： 7376.
