labview_以弹簧-质量-阻尼系统为基础，做出二阶虚拟仪器实验平台_二阶系统的时域，频域响应动态分析

基于labview平台，以弹簧-质量-阻尼系统为基础，做出二阶虚拟仪器实验平台。包括二阶系统的时域，频域响应动态分析。实现单位阶跃信号输入弹簧-质量-阻尼系统后的动画演示。 (Labview based platform to spring- mass- damper system based on virtual instrument to make second order experimental platform. Time domain including second-frequency-domain dynamic response analysis. Per unit step signal input spring- damping system after animation- quality.)
