说明：  使用全局变量 VI 实现动态数据从一个 VI 传送到别一个 VI 中。当两个 VI 同时运行时，观察对比两个 VI 的波形图，调节第一个 VI 的滑动 杆，再观察对比两边的波形，最后，按下第一个 VI 里的停止按钮时，第二个 VI 也能接收到停止信号，并停止第二个 VI 的运行。(Using global variable VI to transfer dynamic data from one VI to another Medium. When the two VI are running at the same time, observe and compare the waveform of the two VI, and adjust the sliding of the first VI Then observe and compare the waveforms on both sides. Finally, when pressing the stop button in the first VI, the second VI It can also receive the stop signal and stop the operation of the second VI.)
