介绍了BEPCII主漂移室带电径迹重建的算法，包括径迹寻找和拟合。研究结果表明，该算法能够在较宽的动量范围内高效地重建带电径迹，并提高了对漂移室背景噪声的鲁棒性。系统的空间分辨率、动量分辨率和次顶点重建效率等总体性能满足BESIII实验的要求。
We describe the algorithm to reconstruct the charged tracks for BESIII main drift chamber at BEPCII, including the track finding and fitting. With a new method of the Track Segment Finder (TSF), the results of present study indicate that the algorithm can reconstruct the charged tracks over a wide range of momentum with high efficiency, while improving the robustness against the background noise in the drift chamber. The overall performances, including spatial resolution, momentum resolution and secondary vertices reconstruction efficiency, etc. satisfy the requirements of BESIII experiment.
