摘　　要：通过比较NI ELVIS和传统设备在物理实验测量中的区别,考察虚拟仪器的适用性、可靠性和准确性。在对电阻、电容等元器件参数、简单串联电路电压电流以及RC电路充放电测量过程中,我们发现虚拟仪器作为实验演示设备具有简单、直观的优点,但作为测量工具,不仅准确性未明显提高,还容易产生偏差并且不易被察觉。本项目结果对研究虚拟仪器的自检自校准功能提出了要求和参考数据。Through the investigation of NI ELVIS explores the applicability, reliability and accuracy application in the physics experiments,this paper of virtual instrument.Through the measurement of resistor, capacitor, series circuit and RC circuit,we found that the virtual instrument has the simple and intuitive merits in the demonstration experiment,but as a measuring tool,compared with the traditional measuring instruments,the accuracy was not significantly improved,even easy to produce deviation and difficult to detect.This result provides the reference data to the research of virtual instrument self- checking and auto-calibration function.
