这是利用微软RTC类库做的Demo，是绝对可以跑的。注意修改include的路径。该程序是测试Call In的。-This is the class library using Microsoft RTC do Demo, it is absolutely the run. Changes include attention to the path. The procedure is to test the Call In.

Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.
