说明：  广义S变换的时频窗口不仅能够随着频 率尺度自适应地调整,而且克服了S变换中时窗函数的变化趋势固定不变的问题,使广义S变换在应用中具有更高的实用性和灵活性。
(Generalized S transform time-frequency window not only with the frequency scale adaptively, and overcome the tendency S transform window function when the problem is fixed, so that the generalized S transform has higher utility in applications and flexibility.)
