PAA ( Piecewise Aggregate Approximation) is a method for representing time series by sliding an equal-width window on the data and dividing the data into segments.

滑动聚集平均近似PAA（Piecewise Aggregate Approximation）是一种表示时间序列的方法，它通过时间序列上滑动一个等宽的滑动窗口将时间序列分成小的区段。

In this paper, we discussed the application of the HOAA method in classical physics.
