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). PLH

在调试过程中由于水平有限，可能有隐含的问题并未能在此次的实验中表现出来，要求完成多时区切换，但由于本人能力有限未能做出，制作出了单一时区的倒计时，由于计算时为严格按照各个月份天数不同及闰年与非闰年差别，在计算倒计时间时不够严谨-In the debugging process because of the limited level, there may be hidden problems and unable in this experiment shown, required to com
