说明：  虚拟仪器技术（VI）就是利用高性能的模块化硬件，结合高效灵活的软件来完成各种测试、测量和自动化的应用。灵活高效的软件能帮助您创建完全自定义的用户界面，模块化的硬件能方便地提供全方位的系统集成，标准的软硬件平台能满足对同步和定时应用的需求。这也正是NI近30年来始终引领测试测量行业发展趋势的原因所在。只有同时拥有高效的软件、模块化I/O硬件和用于集成的软硬件平台这三大组成部分，才能充分发挥虚拟仪器技术性能高、扩展性强、开发时间少，以及出色的集成这四大优势。
(Virtual Instrument Technology (VI) is the use of high-performance modular hardware, combined with efficient and flexible software to complete various tests, measurement and automation applications. Flexible and efficient software can help you create a fully customizable user interface, modular hardware can easily provide a full range of system integration, the standard hardware and software platform can meet the application requirements of synchronization and timing. This is why NI has been leading the trend of testing and measuring industry for the last 30 years. Only with efficient software module I/O hardware software and hardware platform for the integration of the three part, in order to give full play to the virtual instrument technology of high performance, strong expansibility, less development time, and excellent integration of these four advantages.)
