本文采用C++语言和面向对象技术，为BES III探测器漂移室设计了MdcPatRec跟踪算法。该算法使用模式匹配的方法来找到轨迹段，然后将它们联合收割机组合成候选轨迹，然后进行最小二乘拟合。利用仿真数据研究了探测器的跟踪效率、动量分辨率等性能，结果与探测器设计参数一致。该算法也被证明是足够的鲁棒性，以处理强背景预期的BES III实验的数据。
The tracking algorithm, MdcPatRec, is developed for the Drift Chamber of the BES III detector using C++ language and object-oriented techniques. This algorithm uses a pattern matching method to find track segments and then combine them into track candidates followed by a least square fit. With the simulation data, the tracking performances such as efficiencies and momentum resolution have been studied and results are consistent with parameters from detector design. The algorithm is also proved to be robust enough to process data with severe background expected by the BES III experiment.
