再短时傅里叶变换中设置时间分辨率，此时信号的短时傅里叶变换在时间轴上完全局部化而没有频率分辨率-Short-time Fourier transform and then set the time resolution, this time the signal short-time Fourier transform in the timeline is completely localized but not the frequency resolution of

仿facebook的wp时光轴主题，能轻松的让你的博客以时光轴方式显示-Wp time axis of imitation facebook theme can easily make your blog to display the time axis

计算cop 轨迹，图片展示cop，以及时间轴展示三维cop-Calculated cop trajectory Photo Gallery cop, as well as the timeline shows a three-dimensional cop
