adaptive time-frequency excision的用法和样例：
- While most current BSS methods are based on fixed kernel functions, we propose BSS based on adaptive time frequency kernel function to improve the performance of resisting cross terms.
- adaptive time frequency distribution
- A Wiener weighting adaptive time delay estimation algorithm based on frequency domain is presented.
- I can hardly adapt time differences everytime I travel abroad.
- It is possible that the computer is of low grade, and the time frequency is too low, please change for a new computer.
