The fitting difference is reduced and the precise of quantitative interpretation is improved by means of joint TF inversion with time and frequency window data.

利用时间窗数据和频率窗数据所进行的联合时-频反演，缩小了拟合差，提高了定量解释精度。

The time frequency window is adjusted conveniently by using optimum base searching method, moreover, it's not necessary to have stable wave assumption in the window.

通过采用局部余弦最佳基搜索方法，对信息实现不同的时间分割，可非常容易地调整时频窗。 不需要在分析窗内对信号作平稳假定，所得结果与原信号完全同步。
