What Exactly Is LabVIEW,and What Can It Do for Me?
準確地說,什么是LabVIEW,它又能為我做什么呢?
LabVIEW,short for Laboratory Virtual Instrument Engineering Workbench,is a programming environment in which you create programs using a graphical notation (connecting functional nodes via wires through which data flows); in this regard,it differs from traditional programming languages like C,C++,or Java,in which you program with text.However,LabVIEW is much more than a programming language.It is an interactive program development and execution system designed for people,like scientists and engineers,who need to program as part of their jobs.The LabVIEW development environment works on computers running Windows,Mac OS X,or Linux.LabVIEW can create programs that run on those platforms,as well as Microsoft Pocket PC,Microsoft Windows CE,Palm OS,and a variety of embedded platforms,including Field Programmable Gate Arrays (FPGAs),Digital Signal Processors (DSPs),and microprocessors.
LabVIEW是Laboratory Virtual Instrument Engineering Workbench的英文縮寫,它是一種圖形化的編程環(huán)境,使用圖形化的符號來創(chuàng)建程序（通過連線把函數(shù)節(jié)點連接起來,數(shù)據(jù)就是在這些連線上流動的）；在 這點上,它不同于傳統(tǒng)的文本編程語言像C,C++,或者Java.然而,LabVIEW不僅僅是一種編程語言,它是專門為那些工作中需要大量編程的工程師和科學家們設計的一種交互式的程序程開發(fā)和執(zhí)行的系 統(tǒng).LabVIEW開發(fā)環(huán)境可以工作在裝有Windows,Mac OS X,或Linu任何一種操作系統(tǒng)的計算機上.LabVIEW創(chuàng)建的程序可以在上述平臺上運行,同時也可以運行于Microsoft Pocket PC,Microsoft Windows CE,Palm OS和大量的嵌入式平臺,包括現(xiàn)場可編程門陣列(FPGAs),數(shù)字信號處理器（DSPs）和微處理器.
Using the very powerful graphical programming language that many LabVIEW users affectionately call "G" (for graphical),LabVIEW can increase your productivity by orders of magnitude.Programs that take weeks or months to write using conventional programming languages can be completed in hours using LabVIEW because it is specifically designed to take measurements,analyze data,and present results to the user.And because LabVIEW has such a versatile graphical user interface and is so easy to program with,it is also ideal for simulations,presentation of ideas,general programming,or even teaching basic programming concepts.
許多使用功能強大的圖形化編程語言LabVIEW的用戶親切的稱之為“G”語言（取自graphical）,LabVIEW能夠讓你的開發(fā)效率提高 幾個數(shù)量級.使用傳統(tǒng)語言可能需要幾周或者幾個月才能完成的程序,如果用LabVIEW編寫,幾個小時就能完成,其中一個原因是LabVIEW是專為用戶 設計的,用來進行測量,分析數(shù)據(jù)和顯示結果.另一個原因是LabVIEW有豐富的圖形化用戶接口（GUI）,使用這些接口使編程變得很容易.它也非常適合 用來進行仿真,表述思想,編寫一般程序,或者講述基本編程概念.
