Abstract：
This paper introduces a new algorithm that is used to find and fit charged particle tracks in MDC of BES-Ⅱ. The non-numerical pattem recognition technique used in this algorithm is described. The technique is both fast and efficient from the analysed results of M. C. data and experimental data.
