By focusing on the historian s ways of synthesizing and harmonizing the historical materials,this article discusses some of Simaqian s basic ways to write history: primitive exploration,watching the decline as wel.

Two trajectories in batch process can be matched reasonably in endpoint constraints, different local continuity constraints (Itkura constraint, Sakoe Chiba constraint) and different global constraints (Itkura constraint、Sakoe Chiba constraint) respectively, and minimum normalized total distance between two trajectories can be obtained based on dynamic time warping, then optimal path can be foun.
