摘　　要：将虚拟仪器技术引入到电工实验教学中,利用LabVIEW和Multisim联合仿真工具设计了一款二阶RLC回路自由振荡特性分析测试仪。实验结果显示,该分析测试仪可以捕捉普通物理示波器无法获取到的二阶RLC回路瞬态充放电过程,将复杂数学公式描述的此抽象过程动态实时展示,并可借此研究分析电路参数对振荡特性的影响。The ＂ isolation＂ teaching style in the field of electronic teaching in colleges and universities which caused by the asynchrony of theory,simulation and test,lets students not only shuttle between classrooms and laboratories,but also struggle between theory and practice. In order to solve this problem,by integrating these on a same platform,students can achieve the rapid integration and absorption of knowledge. By using Lab VIEW and Multisim,we designed an analysis and testing instrument for free oscillation characteristic of two order RLC circuit. Results show that compared with general physical oscilloscopes,the analyzer can capture the transient charging and discharging process of two order RLC circuit by showing the processes described by complex mathematical formulas in waveform dynamically in real time.It can also help students to study how the oscillation characteristics are influenced by circuit parameters.
