求翻译：由于实际多尺度过程的分析要求时- 频窗口具有自适应性, 即高频时频窗大、时窗小, 低频时频窗小、时窗大, 而STFT的时- 频窗口则固定不变。是什么意思？

Frequency window due to the requirements of the actual multi-scale analysis of the process - has a self-adaptive, high frequency, the frequency window, a small time window and frequency window is small at low frequencies, time windows, stft the - frequency window is fixed .

Due to the fact that actual multi-scale analysis of the process is called frequency window with adaptive, i.e. , high-frequency time-frequency window pane, when small, low-frequency window pane when small, large, and the time-frequency STFT window is fixed.

Because time actual multi-criterion process analysis request - the frequency window has auto-adapted, namely high frequency when frequency window big, when the window is small, low frequency when frequency window small, when the window is big, but STFT time - frequency window then fixed invariable.

As the actual scale processes with Adaptive time-frequency analysis of requirements window, high frequency frequency when window, window for small, low-frequency time-frequency window when the window is small, large, and STFT-frequency when window is not constant.
