50分！高手幫忙翻譯一下: LabVIEWisapowerfulandcomplexprogrammingenvironment.LabVIEWisshortforLaboratoryVirtualInstrumentEngineeringWorkbench.Itisapowerfulandflexibleinstrumentationandanalysissoft... LabVIEW is a powerful and complex programming environment. LabVIEW is short for Laboratory Virtual Instrument Engineering Workbench. It is a powerful and flexible instrumentation and analysis software development application created by the folks at National Instruments—a company that creates hardware and software products that leverage computer technology to help engineers and scientists take measurements， control processes， and analyze and storem data. National Instruments was founded over twenty-five years ago in Austin， Texas by James Truchard (known as Dr. T)， Jeffrey Kodosky， and William Nowlin. At the time， all three men were working on sonar applications for the U.S. Navy at the Applied Research Laboratories at The University of Texas at Austin. Searching for a way to connect test equipment to DEC PDP-11 computers， Dr. T decided to develop an interface bus. He recruited Jeff and Bill to join him in his endeavor， and together they successfully developed LabVIEW and the notion of a “virtual instrument.” In the process they managed to infuse their new company—National Instruments—with an entrepreneurial spirit that still pervades the company today. Engineers and scientists in research， development， production， test， and service industries as diverse as automotive， semiconductor， aerospace， electronics， chemical， telecommunications， and pharmaceutical have used and continue touse LabVIEW to support their work. LabVIEW is a major player in the area of testing and measurements， industrial automation， and data analysis. For example， scientists at NASA’s Jet Propulsion Laboratory used LabVIEW to analyze and display Mars Pathfinder Sojourner rover engineering data， including the position and temperature of the rover， how much power remained in the rover’s battery， and generally to monitor Sojourner’s overall health. LabVIEW provides an extensive library of virtual instruments and functions to help you in your programming. It includes conventional program debugging tools with which you can set breakpoints， single-step through the program， and animate the execution so you can observe the flow of data. 畢業(yè)設(shè)計(jì)急用，望高手幫忙翻譯一下展開
