But, there were relatively few researches of high-speed railway curve parameter with track irregularity excitation at present.

但是，目前在轨道不平顺激励下研究高速铁路曲线参数的比较少。

Based on this assumption, combined with the non-isochronous features of track irregularity time series data, this paper proposes Piecewise Linear Recursive Model based on Short-term Historical Trends model ( PLRMSHT).

基于此假设，并结合轨道不平顺时间序列数据的非等时距特征，论文提出基于非等时距短期历史趋势的时间序列分段线性递推模型（PLRMSHT）。
