此程序为窗函数宽度对时－频分辨率的影响，由于受不定原理的制约，我们对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。-This program is the width of time window functions- frequency resolution, due to the uncertainty principle constraints, we have the time resolution and frequency resolution can only take a compromise, a raised, the other is bound to decrease, and vice versa Ran.
